South Holland
View on Wikipedia
South Holland (Dutch: Zuid-Holland [ˌzœyt ˈɦɔlɑnt] ⓘ) is a province of the Netherlands with a population of over 3.8 million as of January 2023[2] and a population density of about 1,410/km2 (3,700/sq mi), making it the country's most populous province and one of the world's most densely populated areas. Situated on the North Sea in the west of the Netherlands, South Holland covers an area of 3,308 km2 (1,277 sq mi), of which 609 km2 (235 sq mi) is water. It borders North Holland to the north, Utrecht and Gelderland to the east, and North Brabant and Zeeland to the south. The provincial capital is the Dutch seat of government The Hague, while its largest city is Rotterdam. The Rhine-Meuse-Scheldt delta drains through South Holland into the North Sea. Europe's busiest seaport, the Port of Rotterdam, is located in South Holland.
Key Information
History
[edit]Early history
[edit]Archaeological discoveries in Hardinxveld-Giessendam indicate that the area of South Holland has been inhabited since at least c. 7,500 years before present, probably by nomadic hunter-gatherers. Agriculture and permanent settlements probably originated around 2,000 years later, based on excavations near Vlaardingen. In the classical antiquity, South Holland was part of the Roman Province of Germania Inferior, and the border of the Roman Empire ran along the Old Rhine and reached the North Sea near Katwijk. The Romans built fortresses along the border, such as Praetorium Agrippinae near modern-day Valkenburg, Matilo near modern-day Leiden, and Albaniana near modern-day Alphen aan den Rijn. A city was founded near modern-day Voorburg, Forum Hadriani. It was built according to the grid plan, and facilitated a square, a court, a bathhouse and several temples.
After the departure of the Romans, the area belonged to the Frisian Kingdom, after which it was conquered by the Frankish king Dagobert I in 636. In 690, the Anglo-Saxon monk Willibrord arrived near Katwijk and was granted permission to spread Roman Catholicism by the Frankish king Pepin II. He accordingly founded a church in Oegstgeest, after which the entire area was gradually Christianised. The area was appointed to East Francia in the Treaty of Verdun in 843, after which the king granted lands to Gerolf, who had helped him claim the lands. This was the birth of the County of Holland. Gerolf was later succeeded by Dirk I, who continued to rule Holland under the Frankish king. In 1248, count William II ordered the construction of the Ridderzaal, which was later finished by his son and successor Floris V.


The first city in South Holland to receive city rights was Dordrecht, which did so in 1220. The city retained a dominant position in the area until it was struck by a series of floods in the late 14th century. The same century also saw a series of civil wars, the Hook and Cod wars, concerning the succession of count William IV. Both his daughter Jacqueline and his brother John, the latter supported by Philip the Good, Duke of Burgundy, claimed the throne. The conflict ended in 1490, with John victorious.
Overall, the area of South Holland remained largely agrarian throughout the late Middle Ages. This changed around 1500, when Holland became Europe's most urbanised area. During the Eighty Years' War, the area of South Holland was the scene of the Capture of Brielle, the Siege of Leiden and the assassination of William the Silent.
The United Netherlands declared their independence in 1581, and Holland quickly emerged as the country's dominant province, with important trading cities such as Leiden, Delft, Gouda and Dordrecht. In 1575, the Netherlands' first university was founded in Leiden by William the Silent. The Hague, which had originated around the castle of the counts of Holland, became its new political centre. Both the States of Holland and the States General seated in the Binnenhof. The Dutch Golden Age blossomed in the 17th century. The south of Holland, back then often referred to as the Zuiderkwartier (literally "South Quarter"), was the birthplace and residence of scientists such as Antoni van Leeuwenhoek and Christiaan Huygens, philosophers such as Baruch Spinoza and Pierre Bayle, and painters such as Johannes Vermeer, Rembrandt van Rijn and Jan Steen.
As a province
[edit]The province of South Holland as it is today has its origins in the period of French rule from 1795 to 1813. This was a time of bewildering changes to the Dutch system of provinces. In 1795, the Batavian Republic was proclaimed and the old order was swept away by a series of constitutional changes in the following years. In the Constitution enacted on 23 April 1798, the old borders were radically changed. The republic was reorganised into eight departments with roughly equal populations. The south of Holland was split up into three departments. The islands in the south were merged with Zeeland and the west of North Brabant to form the Department of the Scheldt and Meuse. The north of the area became the Department of the Delf. A small region in the east of the area became part of the Department of the Rhine, which spanned much of Gelderland and Utrecht. In 1801, the old borders were restored when the department of Holland was created. The reorganisation had been short-lived, but it gave birth to the concept of a division of Holland, creating less dominant provinces. In 1807, Holland was reorganised once again. This time, the department was split in two. The south, what would later become South Holland, was called the Department of Maasland. This also did not last long. In 1810, all the Dutch provinces were integrated into the French Empire, and Maasland was renamed Bouches-de-la-Meuse.

After the defeat of the French in 1813, this organisation remained unchanged for a year or so. When the 1814 Constitution was introduced, most borders were restored to their situation before the French period. The north and south of Holland were reunited as the province of Holland. However, the division had not completely been undone. Since its re-establishment in 1814, Holland had always had two King's Commissioners, one for the north and one for the south. Even though the province had been reunited, the two areas were still treated differently in some ways and the idea of dividing Holland remained alive. In 1840, it was decided to once again split Holland into North and South Holland, because the province of Holland was deemed too dominant in area, population and wealth. In the late 20th and early 21st centuries, five municipalities were transferred from South Holland to Utrecht; Oudewater in 1970, Woerden in 1989, Vianen in 2002, Leerdam and Zederik in 2019.
The construction of the Nieuwe Waterweg in 1863 marked the start of the growth of the Port of Rotterdam. On 14 May 1940, during the Second World War, the centre of Rotterdam was destroyed by a German bombardment. The subsequent German occupation of the Netherlands resulted in anti-Jewish measures, and many members of Dutch resistance were captured and executed on the Waalsdorpervlakte. At the same time, the Atlantikwall was constructed along the coast. After the Second World War, in 1953, the south of South Holland was heavily struck by the North Sea flood, which took the lives of 677 South Hollanders. After this, the Dutch government decided for the construction of the Delta Works, which came to an end with the completion of the Maeslantkering in 1997.
Geography
[edit]South Holland covers an area of 3,308 km2 (1,277 sq mi), of which 609 km2 (235 sq mi) is water. It borders the North Sea to the west, North Holland to the north, Utrecht and Gelderland to the east, and North Brabant and Zeeland to the south. Beside the dunes along the North Sea coast, the province is almost entirely flat and mostly consists of polders. The centre of South Holland and the area along the coast in the west are largely urban, part of the Randstad conurbation, while the east of the province is more agrarian and belongs to the Groene Hart, literally Green Heart. The south of the province is a collection of islands in the Rhine–Meuse–Scheldt delta. For census reasons, South Holland is divided into five regions: Rijnmond, South, West, East, and Southwest.
The Duin- en Bollenstreek is a region in the northwest of South Holland, around Katwijk, that features coastal dunes and the cultivation of flower bulbs. To the south of the region lie mostly pastures on sand soil, that form the transition to more urban area. This urban area runs along the Old Rhine, from Katwijk via Rijnsburg to Leiden and Zoeterwoude-Rijndijk. South of Leiden and north of The Hague lies an area where a landscape of dunes bordering the North Sea in the west transitions to one of peat more to the east. The easternmost tip of South Holland is part of De Biesbosch, one of the largest national parks of the Netherlands and one of the last freshwater tide areas in Europe. Other parks in South Holland, although no national parks, include Delftse Hout east of Delft,[5] Ackerdijkse Plassen, a bird reserve north of Rotterdam,[6] and Buytenpark and Westerpark near Zoetermeer.[7] The Kagerplassen are a collection of lakes north-east of Leiden, popular for boating, watersports, fishing, camping and walking.
The southern part of South Holland consists of a number of islands of the Rhine–Meuse–Scheldt delta. Although technically islands in the sense that they are surrounded by rivers, canals or other bodies of water, most of these islands are well connected to the rest of the province via bridges, tunnels and dams. The southern islands, most notably Goeree-Overflakkee (1 on the map), Tiengemeten (2), Hoeksche Waard (6) and Voorne-Putten (4/5), are largely agrarian, while more to the north, the islands are more urban, such as Dordrecht (7), IJsselmonde (9) and Rozenburg (10), while other islands, like Rozenburg (10), are mostly used for petrochemical industry. Together, these cities form the Rijnmond conurbation, centred on the city of Rotterdam. Together with Haaglanden (centred on The Hague) and Delfland (centred on Delft) in the north, and the Drechtsteden to the south-east, this conurbation in turn forms the South Wing of the Randstad conurbation, which spans across South Holland, North Holland and Utrecht.
Other regions in South Holland include Alblasserwaard, Gouwestreek ("The Gouwe Area"), Hoeksche Waard, Krimpenerwaard, Rijnland ("Rhineland"), Rijnstreek ("The Rhine Area"), Vijfheerenlanden and Westland (roughly including Hook of Holland and the municipalities of Westland and Midden-Delfland).

Climate
[edit]Like the rest of the Netherlands, South Holland experiences a temperate oceanic climate, a Cfb-class according to the Köppen climate classification. The climate is influenced by the North Sea and the Atlantic Ocean, which results in relatively cooler summers and milder winters. Rain showers are common in the fall and winter seasons. Because of the flat surface, wind storms are also not uncommon in the winter. Although rain occurs all year long, the first six months of the year are relatively dry. Eastern winds can result in temporary continental climate conditions with relatively warm and dry summers and cold and stormy winters. The temperature varies between the 2 °C and 6 °C in the winter and 17 °C and 20 °C in the summer.

The main sectors of economical activity in this province are among others:
- Horticulture is an important sector in South Holland. The province is home to around 2550 glasshouse companies, approximately half of the Netherlands' total.[12] Specifically the Westland is well known for its intensive horticulture. The glasshouses in this region cover an area of 2,750 hectares (10.6 sq mi),[13] making it the world's largest contiguous greenhouse area.[14]
- Flower bulb cultivation;
- Port of Rotterdam;
- Petrochemical industry, particularly near Rotterdam neighbourhood Pernis; (Shell's refinery there is the largest oil refinery in Europe, and one of the largest in the world);
- The service-oriented economy of The Hague, where many jobs are offered by the national government (of which the main administrative parts are settled in this town), international institutions and headquarters of several large international businesses;
- Tourism-related activities (among others in historic places like Delft, and several seaside resorts);

Prehistoric and early medieval periods
The Rhine-Meuse delta region encompassing modern South Holland preserves evidence of Mesolithic hunter-gatherer activity from approximately 8500 to 5000 BC, with key finds including human skull fragments and tools recovered from coastal sites at Maasvlakte 2 near Rotterdam, reflecting adaptation to post-glacial wetlands and marine resources.[6] These communities relied on fishing, hunting, and seasonal mobility amid fluctuating sea levels and peat accumulation that later submerged earlier Paleolithic traces.[7] Neolithic transition occurred around 5500–3400 BC, marked by semi-sedentary settlements in the delta such as Hardinxveld-Giessendam Polderweg and De Bruin, where excavations uncovered pottery, domesticated cattle remains, and hut structures indicating early agriculture and resource management in fertile alluvial soils.[8] These sites, part of the Swifterbant culture, demonstrate gradual adoption of farming alongside foraging, with Bayesian modeling confirming occupation phases from circa 3650–3375 cal BC, predating widespread sedentism elsewhere in the Low Countries.[8] Bronze Age (circa 2000–800 BC) and Iron Age (800 BC–AD 1) habitation remained sparse due to expanding marshes and dunes, featuring urnfield burials and terp (mound) villages in coastal zones like Goeree-Overflakkee, inhabited by proto-Germanic groups with iron tools and trade links to Celtic interiors.[9] By the late Iron Age, Cananefates and other Germanic tribes dominated, with evidence of fortified farmsteads reflecting defensive needs against flooding and raids. From the 1st century BC to the 4th century AD, the area integrated into Roman Germania Inferior as a frontier zone, with the Oude Rijn (Old Rhine) branch forming part of the limes defenses; castella like those near Alphen aan den Rijn housed auxiliary troops, while civilian vici and villas supported agriculture and pottery production in drier inland pockets.[10] Roman withdrawal circa AD 410 left infrastructure decay amid Saxon incursions, transitioning the depopulated peat moors to Frisian maritime tribes who controlled coastal trade routes into the 7th century.[11] The early medieval period (5th–10th centuries) saw Frankish conquest of Frisian holdings by AD 689 under Pepin of Herstal, incorporating the region into Austrasia with Dorestad (near modern Wijk bij Duurstede, influencing delta commerce) as a Carolingian emporium handling Frisian-English trade until its silting around AD 863.[12] Sparse settlements emerged on natural levees and early dikes, fostering proto-Dutch dialects and Christian missions from Utrecht, though much of the interior remained uncultivated wilderness prone to inundation.[13] By the 9th century, local counts under Carolingian suzerainty initiated drainage efforts, laying groundwork for the 10th-century County of Holland centered at Dordrecht.[13]County of Holland and late medieval developments
The County of Holland emerged in the 10th century as a feudal territory under the House of Holland, initially centered in the Rhine-Meuse delta region that forms the core of modern South Holland. Dirk III (r. 993–1039), often regarded as the first count to bear the title formally, expanded control by seizing lands from the Bishopric of Utrecht, including key areas around Dordrecht, which he founded circa 1015 as a strategic river fortress and residence. In 1018, Dirk III decisively defeated imperial forces led by Emperor Henry II at the Battle of Vlaardingen, securing de facto autonomy from direct ecclesiastical and imperial oversight while affirming vassalage to the German king. This victory, involving roughly 1,500 Frisian warriors against a larger German contingent, marked a pivotal assertion of local authority over toll rights on vital trade routes like the Meuse estuary.[14][15] By the 13th century, under counts like Floris IV (r. 1222–1234) and his son Floris V (r. 1256–1296), the county experienced territorial consolidation and infrastructural advancements critical to the marshy delta's habitability. Floris V, succeeding as a minor after his father's death in tournament at Corbie in 1234, pursued aggressive expansion, acquiring Zeeland through inheritance in 1290 and initiating campaigns against West Frisia from 1282, incorporating northern territories by 1289 via fortified border castles and alliances. He championed peasant interests against noble privileges, earning the moniker "God of the Commons" (Keerlen God), and reformed administration by chartering towns like Geertruidenberg and promoting herring fisheries with innovations in net technology. Water management advanced markedly, with Floris V establishing early waterschappen (water boards) to coordinate dike construction and peat drainage, reclaiming thousands of hectares of bogland and enabling agricultural surplus in the IJsselmeer precursor areas; by his reign's end, Holland's population approached 200,000, fueled by these efforts. His pro-French alliances, including a 1294 treaty with Philip IV of France, provoked noble unrest, culminating in his 1296 abduction and murder by conspirators led by Willem van Egmond near Dordrecht, triggering succession crises.[16][17] Late medieval Holland transitioned through dynastic shifts that integrated it into larger Low Countries polities, with South Holland's urban centers like Delft, Leiden, and Rotterdam emerging as trade hubs. After Floris V's death, the county passed via his daughter Margaret to the Bavarian House of Wittelsbach in 1345 under William III (r. 1316–1345 in personal union), whose military prowess during the Hundred Years' War, including victories at Staveren (1345), bolstered Holland's naval strength with a fleet of over 20 warships. Margaret's granddaughter Jacqueline of Hainaut (r. 1417–1433) inherited amid fratricidal conflicts with her uncle John III of Brabant, leading to prolonged wars that devastated Zeeland but preserved Holland's core integrity. Exhausted by defeats, Jacqueline ceded effective control to Philip III the Good of Burgundy via the 1428 Concordat of Delft and fully abdicated in 1433, incorporating Holland into the Burgundian Netherlands as an apanage with 16 major towns represented in estates. This era saw economic maturation through textile exports and Hanseatic trade, though feudal tensions persisted; Burgundian centralization imposed standardized coinage and taxation, yielding annual revenues exceeding 300,000 guilders by mid-15th century, while resisting full feudal absorption to maintain local privileges.[18][19]Dutch Revolt, Golden Age, and Republic era
The County of Holland, encompassing the territory of present-day South Holland, emerged as a stronghold of resistance during the Dutch Revolt against Spanish Habsburg rule, which ignited in 1566 with iconoclastic riots and escalated into open warfare by 1568. The province's maritime trade interests and relative tolerance for Protestantism fueled opposition to Philip II's centralizing policies, heavy taxation, and enforcement of Catholicism. In 1572, cities such as Dordrecht and Leiden aligned with William of Orange, marking early rebel successes in the region. The Siege of Leiden from October 1573 to October 1574 exemplified the province's endurance, as Spanish forces under Francisco de Valdez blockaded the city, leading to severe famine and disease that halved its population; relief arrived on October 3, 1574, when rebels breached surrounding dikes, flooding polders to enable a flotilla of ships carrying food to break through, a tactic that preserved the city's defiance and galvanized northern support.[20][21] In gratitude for Leiden's loyalty, William of Orange chartered Leiden University on February 8, 1575, establishing it as a center for Protestant scholarship that would later contribute to scientific advancements during the ensuing prosperity. The revolt culminated in the 1581 Act of Abjuration, renouncing Spanish allegiance, and the formation of the Republic of the Seven United Provinces, with Holland—dominated by its southern cities—providing the bulk of financial resources and exerting disproportionate influence over federal decisions. The Hague, lacking municipal privileges but strategically located, became the de facto political hub by 1588, hosting assemblies of the States General and provincial estates in the Binnenhof complex, where stadtholders of the House of Orange-Nassau coordinated defense and diplomacy.[21][22][23] The Peace of Westphalia in 1648 formalized independence, ushering in the Golden Age (circa 1588–1672), when South Holland's ports and institutions thrived amid global trade expansion. Rotterdam developed as a key entrepôt for Baltic grain and colonial goods, complementing Amsterdam's dominance, while Delft and Gouda specialized in ceramics and cheese exports, respectively, fueling urbanization and wealth accumulation. Holland's economic primacy, accounting for over half the Republic's tax revenue, underpinned naval supremacy and cultural efflorescence, including advancements in optics and anatomy at Leiden University. Governance remained decentralized, with the States of Holland wielding veto power in federal matters, though tensions between regents and Orange stadtholders periodically disrupted stability, as seen in the 1650 execution of anti-Orange leader Johan de Witt in The Hague amid the First Anglo-Dutch War.[23][24]19th-century industrialization and 20th-century wars
The industrialization of South Holland in the 19th century was driven primarily by the expansion of maritime trade and port infrastructure in Rotterdam, which transitioned from a fishing harbor to a major commercial gateway handling Dutch colonial goods and European industrial commodities like steel and coal.[5] By the mid-19th century, the port's growth facilitated the import of raw materials and export of processed goods, supporting emerging industries such as shipbuilding, metalworking, and early chemical processing in the region's delta lowlands.[25] This selective industrialization, lagging behind Britain's due to limited domestic coal and iron resources, emphasized agricultural mechanization and export-oriented processing rather than heavy manufacturing, with Rotterdam's docks expanding to accommodate steamship traffic and Rhine River connections to German industrial areas.[26] During World War I, the Netherlands, including South Holland, remained neutral, avoiding direct combat but suffering economic disruptions from Allied blockades and disrupted trade routes, which curtailed exports and caused shortages in the port-dependent economy of Rotterdam.[27] The mobilization of Dutch forces strained resources, while neutral shipping faced interdiction, leading to a contraction in maritime activity and contributing to postwar economic pressures without territorial damage.[28] In World War II, German forces invaded the Netherlands on May 10, 1940, rapidly overrunning defenses in South Holland; Rotterdam endured the Blitz on May 14, when Luftwaffe bombers destroyed the city center in a 15-minute attack, killing approximately 900 civilians, rendering 80,000 homeless, and demolishing 24,000 homes to coerce surrender.[29] The subsequent occupation exploited South Holland's ports and industries for the German war effort, including forced labor in Rotterdam's shipyards and confiscation of delta farmlands, exacerbating food shortages that culminated in the Hunger Winter of 1944–1945, where western provinces like South Holland saw civilian deaths from starvation exceed 20,000 nationwide due to rail and flood defenses blocking supplies.[30] Resistance activities, including sabotage at Waalhaven airfield and strikes in Rotterdam, met harsh reprisals, while the region's Jewish population faced systematic deportation, with over 70% perishing in camps owing to efficient bureaucratic collaboration under occupation authorities.[31] Liberation by Allied forces in May 1945 followed Operation Market Garden's partial successes and Canadian advances, leaving South Holland's urban cores scarred but its strategic ports intact for reconstruction.[32]Post-WWII reconstruction and provincial formation
Following the liberation of the Netherlands in 1945, South Holland undertook extensive reconstruction efforts to repair war damage, with Rotterdam serving as the focal point due to its near-total devastation from the German Blitz on 14 May 1940, which razed the city center and killed approximately 900 civilians. Rather than restoring pre-war architecture, planners adopted a modernist approach emphasizing functional urban design, broad avenues, and high-rise structures, coordinated through the Basic Plan for the Reconstruction of Rotterdam's City Center approved in 1946. This period, often termed the "Reconstruction Era" from 1945 to around 1968, prioritized rapid housing and infrastructure development, incorporating influences from the International Congresses of Modern Architecture (CIAM) to create a resilient port city.[33][34] The province's economy rebounded swiftly, driven by the expansion of the Port of Rotterdam, which saw new docks and oil refineries operational by the 1960s, leveraging its strategic Rhine delta location for transshipment trade. Federal aid via the Marshall Plan supplied critical funds and materials for nationwide recovery, including in South Holland, facilitating industrial modernization and alleviating post-war shortages in housing and energy. Provincial authorities coordinated municipal initiatives, integrating polder management and land-use planning to support population influx and urbanization in the Randstad conurbation.[35] A major setback occurred with the North Sea flood of 31 January–1 February 1953, which breached dikes and inundated low-lying areas, resulting in 677 fatalities in South Holland amid 1,836 total Dutch deaths, alongside the loss of tens of thousands of livestock and flooding of 162,000 hectares. This disaster accelerated provincial involvement in water management reforms, culminating in the Delta Works project launched in 1958—a series of dams, sluices, and barriers to fortify coastal defenses, fundamentally reshaping South Holland's topography and administrative oversight of hydraulic engineering.[36][37] South Holland's provincial boundaries and governance structure, established by the 1840 division of the former Holland province into northern and southern halves to balance administrative burdens post-Belgian secession, remained largely intact post-WWII, with minor municipal adjustments such as the 1970 transfer of Oudewater to Utrecht. The post-war era reinforced the province's role in centralized planning under the national Ministry of Reconstruction and Housing, enabling coordinated responses to demographic pressures and economic specialization in logistics and agriculture.[38]Geography
Location, borders, and administrative divisions
South Holland occupies the western region of the Netherlands, extending along the North Sea coastline. The province encompasses parts of the Rhine-Meuse-Scheldt delta, with its territory shaped by historical land reclamation efforts from surrounding waters. Its total land area measures approximately 2,460 square kilometers, excluding water bodies. The province shares land borders with North Holland to the north, Utrecht and Gelderland to the east, North Brabant to the southeast, and Zeeland to the south, while the North Sea forms its western boundary. These borders largely follow historical waterways and provincial delineations established since the 19th century, with minor adjustments over time due to municipal mergers.[39] Administratively, South Holland is subdivided into 50 municipalities, which serve as the primary local government units responsible for services such as zoning, public transport, and waste management. This structure results from ongoing consolidations, reducing the number from over 100 in the mid-19th century to the current count through mergers aimed at improving efficiency. The provincial government coordinates supra-municipal policies but does not directly administer these divisions.[40]Topography, land reclamation, and municipalities
South Holland occupies the central portion of the Rhine-Meuse-Scheldt delta, resulting in a predominantly flat topography dominated by alluvial plains, river channels, and reclaimed wetlands. The province's terrain averages near sea level, with extensive areas protected by dikes and featuring intricate networks of canals and waterways that facilitate drainage and transport. Along the North Sea coast, narrow dune belts rise modestly, while inland polders extend across much of the landscape, interspersed with former islands such as Goeree-Overflakkee and Voorne-Putten.[41][1] Significant portions of South Holland lie below mean sea level, necessitating ongoing land reclamation efforts that date back to the medieval period. Polders, enclosed tracts of land reclaimed through diking and drainage, constitute a major feature, with historical projects employing windmills for water expulsion beginning around the 12th century in delta regions. Notable examples include the Bodegraven polder, a 4,672-hectare peat meadow area managed for agriculture and flood control, and broader delta reclamations that expanded arable land amid subsidence risks from peat oxidation. Modern interventions, such as mechanical pumping stations post-19th century, have sustained these areas, though approximately 26% of the national territory below sea level concentrates in provinces like South Holland, heightening vulnerability to flooding without protective infrastructure. The lowest point, Zuidplaspolder at -6.76 meters, underscores the engineered nature of the terrain.[42][43][44] The province encompasses 50 municipalities, varying from densely urban centers to rural polder communities, which collectively manage local governance, zoning, and water boards integral to reclamation maintenance. Key urban municipalities include Rotterdam, the Netherlands' largest port city situated at the New Meuse river mouth, and The Hague, the political seat with coastal dunes; others like Dordrecht and Leiden anchor historical delta trade hubs. These divisions reflect a blend of conurbations in the west, the central Green Heart's agricultural polders, and eastern riverine zones, with water boards coordinating cross-municipal flood defenses.[45][43]Climate and environmental features
South Holland exhibits a temperate maritime climate typical of the western Netherlands, with mild winters and cool summers moderated by the North Sea and prevailing westerly winds. Average annual temperatures range from about 3°C in January to 17°C in July, with an yearly mean of approximately 10.5°C recorded in Rotterdam.[46] Annual precipitation averages around 800 mm, distributed fairly evenly across the months, though autumn and winter tend to be wetter, contributing to frequent cloudy conditions.[47] Extreme weather events, such as storms, occasionally bring heavy rainfall and gusty winds, but the region's flat topography amplifies flood risks rather than temperature extremes.[48] Environmentally, the province is defined by its deltaic position in the Rhine-Meuse-Scheldt estuary, where extensive land reclamation has created polders covering much of the area, with about 20% of the land lying below sea level.[49] This reclaimed terrain relies on an intricate network of dikes, canals, and pumping stations for water management, a system continually upgraded through projects like the Delta Works, initiated after the 1953 North Sea flood that affected South Holland.[50] Coastal features include dunes and beaches that serve as natural barriers, enhanced by innovative measures such as the 2011 Sand Motor project near The Hague, which nourishes shorelines with 21.5 million cubic meters of sand to combat erosion and sea-level rise.[51] The estuarine environment introduces pollutants from upstream rivers, concentrating contaminants in sediments and affecting water quality, while intensive horticulture—particularly greenhouse complexes in areas like Westland—drives high resource demands, including groundwater extraction and energy consumption for climate-controlled cultivation.[52] These activities support bulb fields and floriculture but contribute to nutrient runoff and habitat fragmentation, though protected wetlands and nature reserves, such as those in the Nieuwkoopse Plassen, preserve biodiversity amid urbanization.[53] Ongoing climate adaptation efforts focus on resilient infrastructure to mitigate rising sea levels and intensified precipitation, projected to increase flood probabilities.[54]Demographics
Population trends and density
South Holland possesses the largest population among the Netherlands' provinces, numbering 3,805,000 inhabitants as of January 1, 2023, with projections indicating growth to approximately 3,863,000 by 2025.[55] This equates to a population density of 1,432 inhabitants per square kilometer of land area, surpassing all other provinces and reflecting intense urbanization in the Randstad core.[56] The province's land area totals roughly 2,700 km², excluding water bodies that comprise about 18% of its territory.[57] Population growth has been consistent since the late 20th century, rising from 3,325,000 in 1995—a 16% increase over three decades—driven primarily by net international migration and a surplus of births over deaths.[55] Annual increments accelerated in recent years; for instance, the province recorded the Netherlands' highest absolute growth of 22,460 residents in 2024, fueled by immigration to urban centers like Rotterdam and The Hague.[58] Earlier post-World War II expansion stemmed from industrialization and port development, concentrating residents in the western delta regions, while rural areas experienced relative stagnation. This density, over three times the national average of 533 per km², underscores pressures on infrastructure and land use, with more than 80% of inhabitants residing in municipalities exceeding 100,000 residents.[59] Future projections from Statistics Netherlands anticipate sustained but moderating growth through 2050, contingent on migration patterns and fertility rates below replacement levels.[60]Ethnic composition, immigration patterns, and religion
As of 1 January 2022, 64.3 percent of South Holland's population had a Dutch migration background, defined by CBS as individuals born in the Netherlands with both parents also born in the Netherlands; 10.8 percent had a Western migration background (born abroad in Europe excluding Turkey, North America, Oceania, Indonesia, or Japan, or second-generation equivalents); and 24.9 percent had a non-Western migration background (born abroad elsewhere or second-generation equivalents).[61] Among non-Western groups, the largest shares originate from Turkey (around 4 percent of the provincial total), Morocco (3.5 percent), Suriname (3 percent), and the Dutch Caribbean (2 percent), concentrated in urban areas like Rotterdam and The Hague where non-Western backgrounds exceed 40 percent of residents.[62] This composition reflects higher diversity than the national average of 71 percent Dutch background, driven by the province's role as an economic hub in the Randstad conurbation.[63] Immigration to South Holland has historically included post-World War II labor recruitment from Turkey and Morocco in the 1960s-1970s for industrial and port work, followed by Surinamese inflows after independence in 1975, and family reunification thereafter.[64] Recent patterns show annual net migration of around 20,000-25,000 persons to the province, contributing over 80 percent of population growth since 2010, with inflows dominated by EU labor migrants (e.g., Poles, Bulgarians for logistics and agriculture) and non-EU knowledge workers (e.g., Indians, Chinese for tech sectors in Delft and Leiden).[65] In 2023, provincial immigration totaled approximately 50,000, down from peaks in 2022 due to reduced Ukrainian refugee arrivals post-2022 invasion and tighter national policies, though family and study migration persist; asylum-related settlement remains low relative to national figures, at under 5 percent of inflows.[66] Emigration is higher among Western groups, yielding net gains primarily from non-Western sources.[63] Religiously, South Holland aligns with national secularization trends but retains a Protestant historical imprint from the Dutch Reformation, with Reformed communities in areas like the Groene Hart. As of 2022 surveys, approximately 52 percent of residents aged 15+ report no religious affiliation, 18 percent identify as Protestant (including Dutch Reformed and smaller orthodox groups), 15 percent as Roman Catholic (higher in southern municipalities near North Brabant), 8 percent as Muslim (largely Sunni from Turkish, Moroccan, and Surinamese origins), and 7 percent as other faiths including Hinduism and non-denominational Christianity.[67] Church attendance is low at under 10 percent weekly, except in orthodox Protestant enclaves where it exceeds 50 percent; Islam shows higher participation rates among youth with migrant backgrounds.[68] The rise in unaffiliated persons from 40 percent in 2000 reflects generational shifts and immigration of secular or nominally religious groups, though Muslim identification has grown from 4 percent in 2010 due to family migration and higher fertility.[69]Government and Politics
Provincial governance structure
The provincial governance of South Holland follows the standard structure outlined in the Dutch Constitution and the Provincial Act (Provinciwet), comprising the Provincial States (Provinciale Staten) as the legislative body, the Executive Council (Gedeputeerde Staten) as the administrative executive, and the King's Commissioner (Commissaris van de Koning) as the crown-appointed representative who chairs the executive and ensures alignment with national interests.[70] The Provincial States holds ultimate authority over provincial policy, including spatial planning, environmental protection, infrastructure, and economic development, while delegating operational execution to the Executive Council.[70] The Provincial States consists of 55 seats, allocated proportionally based on the province's population of approximately 3.7 million as of 2023, making it the largest such assembly in the Netherlands. Members are elected directly by residents every four years via open-list proportional representation, with a 0.67% electoral threshold; the most recent elections occurred on March 15, 2023, resulting in a fragmented council where the Farmer-Citizen Movement (BBB) secured the largest bloc with 15 seats, followed by the People's Party for Freedom and Democracy (VVD) with 10.[71] The assembly convenes regularly to approve budgets, ordinances, and major policies, and it elects the Executive Council from its members or external candidates, typically forming a coalition reflecting the balance of power.[70] The Executive Council, currently comprising nine deputies including the King's Commissioner as chair, implements provincial decisions and manages daily administration across portfolios such as mobility, sustainability, and agriculture.[72] As of October 2025, key members include Mariëtte van Leeuwen (BBB, deputy for economic affairs), Frederik Zevenbergen (VVD, deputy for finance), and Aad Straathof (BBB, deputy for agriculture), formed post-2023 elections to reflect the BBB-VVD-CDA coalition.[72] Deputies serve four-year terms aligned with Provincial States elections and are accountable to the assembly, which can dismiss them via no-confidence votes. The King's Commissioner, Wouter Kolff (VVD), appointed by royal decree on September 1, 2024, for a six-year term, oversees provincial-national coordination, chairs Executive Council meetings, and mediates inter-municipal disputes.[73] Kolff succeeded Jaap Smit (CDA) and holds veto power over decisions conflicting with national law, while also serving as the province's liaison to the central government.[74] This tripartite structure ensures democratic representation alongside executive efficiency and monarchical oversight, adapted to South Holland's dense urbanization and economic significance.[70]Political landscape, parties, and recent elections
The Provincial Council (Provinciale Staten) of South Holland, the province's legislative body, comprises 55 members elected through open-list proportional representation for four-year terms, reflecting the Netherlands' multi-party system where seats are allocated via the d'Hondt method.[71] The council sets policy priorities, approves budgets, and elects the provincial executive (Gedeputeerde Staten), typically consisting of 5–9 deputies from coalition parties, while the King's Commissioner—currently Jaap Smit of the Christian Democratic Appeal (CDA) since 2019—chairs the executive and represents the monarch.[75] Politics in the province mirrors national trends but is influenced by its urban-rural divide: Rotterdam and The Hague lean toward progressive parties like GroenLinks and D66, while polder and horticultural areas favor agrarian and conservative groups such as BBB and the Reformed Political Party (SGP).[76] Dominant parties include the liberal People's Party for Freedom and Democracy (VVD), the agrarian BoerBurgerBeweging (BBB, emphasizing farmer interests amid nitrogen emission regulations), the green-left GroenLinks, the social-democratic Labour Party (PvdA), the centrist CDA, and the right-wing Party for Freedom (PVV). Smaller factions like the animal-rights Party for the Animals (PvdD), Christian Union (CU), and Forum for Democracy (FvD) hold influence on issues such as environmental policy, infrastructure, and water management. The council also indirectly elects 12 of South Holland's delegates to the Senate (Eerste Kamer), impacting national legislation.[71] Provincial elections occur concurrently with water board votes every four years; the most recent, on 15 March 2023, saw a voter turnout of approximately 64% and marked BBB's breakthrough amid protests against agricultural restrictions.[77] Provisional results initially projected BBB with 9 seats, but the definitive count confirmed 8, tying it with VVD.[78] In September 2023, GroenLinks and PvdA merged their factions, forming the largest bloc with 10 seats.[79]| Party | Votes (%) | Seats |
