History

[edit]

Saint-Imier is first mentioned in 884 as cella de sancti Himerii. The municipality was formerly known by its German name St. Immer, however, that name is no longer used.[1] Its name refers to Imerius of Immertal, a 7th-century saint.

According to the legend of St. Imerius, he settled in the valley as a hermit in the late 6th or early 7th century on a piece of land that bishop Marius of Lausanne gave him as a present. In 884 a cella (probably a church, farm and monastery) was mentioned on the site. Archeological excavations around the former Church of St. Martin indicate that a village grew up around the cella around the same time. Two of the 142 graves from the church have been dated to the Early Middle Ages and the church was rebuilt at least three times before the 14th or early 15th century.[1]

In 884 the cella with its outbuildings belonged to Moutier-Grandval Abbey. In 999, the Abbey donated Saint-Imier and a number of surrounding villages to the Prince-Bishop of Basel. In 1264, the Bishop appointed Otto of Arguel (or Erguel) as the vogt over the Saint-Imier valley fief. Otto raised the valley to become a seigniory and parish of the Diocese of Basel. By the end of the 15th century, Saint-Imier included the villages of Villeret, Sonvilier, Renan and La Ferriere.[1]

Even though the physical valley was owned by the Bishop of Basel, religiously it was part of the Diocese of Lausanne. The Saint-Imier parish was probably founded in the 9th or 10th century. A village chapel was first mentioned in 968, with the parish church of St. Martin first appearing in the records in 1228. The church of St. Martin was later rebuilt in the gothic style. Another church, the collegiate church was built in the 11th century, probably under the direction of the Bishop of Basel. In 1530, Biel encouraged Saint-Imier to embrace the Protestant Reformation and convert to the new religion. The collegiate church before the parish church for the new Reformed parish. Over the following centuries, the Church of St. Martin was used less and less until it was demolished in 1828. In 1814 the town and the surrounding valley transferred from Lausanne to the Diocese of Basel. Catholic church services resumed in Saint-Imier in 1857 and in 1866 the neo-gothic Church of St. Martin was built. In 1912 a Christian Catholic church was built in the town.[1]

The Hôtel de la maison de Ville in Saint Imier. The Anti-authoritarian International was founded there on a congress taking place on September 15/16, 1872.

In 1792 Théodore Frédéric Louis Liomin, the vogt or bailiff of Saint-Imier, threw his support behind the revolutionary movement that was sweeping the region. After the 1797 French victory and the Treaty of Campo Formio, Saint-Imier became part of the French Département of Mont-Terrible. Three years later, in 1800 it became part of the Département of Haut-Rhin. After Napoleon's defeat and the Congress of Vienna, Saint-Imier was assigned to the Canton of Bern in 1815.[1]

During the 19th century the anti-authoritarian or anarchist movement gained a foothold in the region. In 1872, the Jura Federation, which had strong support in Saint-Imier, organized a congress in Saint-Imier at which the Anti-authoritarian International was founded.[1]

During the 18th century the inhabitants of the valley gradually gave up agriculture in favor of more lucrative jobs in the watch and lace-making industries. The first watch parts workshop opened in the 1720s and the industry continued to expand throughout the 19th century. By 1817 there were about 200 workers employed in either watchmaking workshops or small shops at home. The small scale workshops were replaced by large factory work, when Longines opened a factory in the town in 1867. By the end of the year, 1,600 people were employed in 47 watchmaking companies. Because the town's economy was so dependent on watchmaking, the economic crisis of the 1930s and the 1970s hit Saint-Imier hard. By the beginning of the 21st century, there were about ten watchmaking companies and the economy had diversified to include dental and medical technology and meteorology.[1]

Portions of the town were destroyed by fire in 1839, 1843 and 1856. A hospital opened in Saint-Imier in 1856. In 1874 the town was connected to the Swiss rail network. The town's infrastructure was modernized early, before 1900 it had municipal water, gas and electricity. Saint-Imier has grown into a regional education center. The town's secondary school opened in 1860, followed by a watchmaker's school in 1866. The watch-maker's school was expanded into a machinist's school in 1896 and a technical vocational school in 1961. In 1976 it became a school of engineering and in 2005 it was integrated into the Haute école Arc/Hochschule Arc. A number of other schools opened in the town including the Bernese Jura Music School (1981), a vocational and technical school (1997), and a training center for health professionals (1993).[1]

On 31 December 2009, the district of Courtelary, the municipality's former district, was dissolved. On the following day, 1 January 2010, a new district (or arrondissement administratif) of Jura bernois was created, which includes all of the former Courtelary District, as well as the former district of La Neuveville and the area around Tavannes.[2]

On 19 July 2023, hundreds of anarchists began arriving in Saint-Imier to participate in an international anarchist gathering, in celebration of the 150th anniversary of the Saint-Imier Congress. The event included lectures, workshops, concerts, film screenings, theatre plays, exhibitions and a book fair.[3] By the second day of the event, thousands of people had arrived in the town, causing logistical issues for the self-managed space.[4] The event also caused some safety problems, as its campsite was located next to train tracks that campers often crossed over in order to get to the event location, despite attempts by the event organisers to stop them. In order to guarantee safety, the Swiss Federal Railways halted all rail traffic between Saint-Imier and La Chaux-de-Fonds over the weekend, organising replacement bus services in order to maintain the public transit network.[5][6] The event would end up counting 5,000 attendees, mostly people in their early twenties, who were reportedly warmly welcomed by the town's population. Saint-Imier mayor Corentin Jeanneret reported that the event went largely smoothly, with the exception of a few cases of graffiti.[7][8][9]

Saint-Imier is a municipality in the Jura bernois administrative district of the canton of Bern, Switzerland, situated in the French-speaking Bernese Jura region at an elevation of about 820 meters. With a population of approximately 5,176 as of 2024, it covers an area of 20.89 square kilometers and features a density of around 248 inhabitants per square kilometer. The town is renowned for its longstanding watchmaking tradition, serving as the founding location of the Longines watch company in 1832 by Auguste Agassiz, which remains the sole original watchmaking firm still operating there and exemplifies the shift toward industrial-scale production in Swiss horology. Additionally, Saint-Imier holds historical significance as the site of the 1872 Saint-Imier Congress, where anti-authoritarian socialists, led by figures like Mikhail Bakunin, rejected the centralized Marxist approach of the First International's Hague Congress and established the Anti-authoritarian International, marking a foundational split in the global workers' movement toward federalist and anarchist principles. The local economy continues to draw on this industrial heritage, complemented by educational institutions and proximity to the Jura Mountains, which support tourism and regional agriculture.

Geography and Environment

Location and Topography

Saint-Imier is a in the Jura bernois administrative district of the , , positioned in the French-speaking region. It lies at geographic coordinates approximately 47.15°N 7.00°E. The town occupies a central position in the Vallée de Saint-Imier, a north-south oriented valley within the folded , flanked by ridges and plateaus characteristic of the Swiss Jura fold belt. The settlement sits at an elevation of 814 meters above sea level, with surrounding terrain rising to higher altitudes that define its topography. Immediately north of Saint-Imier, Mont Soleil ascends to 1,291 meters, offering panoramic views over the valley and exemplifying the undulating karst-influenced landscape of pastures, forests, and gentle slopes typical of the Jura. The valley floor provides relatively flat land for urban development and agriculture, while the encircling hills support hiking trails and limit expansion, contributing to a compact municipal footprint of about 20.87 square kilometers. This topography influences local accessibility, with the valley serving as a natural corridor for transportation routes connecting to nearby cities like to the east and to the west. The Jura's bedrock underlies the area's hydrology, featuring streams like the Birse River and occasional sinkholes, though the immediate vicinity around Saint-Imier remains agriculturally viable without pronounced hazards.

Climate and Natural Features

Saint-Imier lies in the Vallon de Saint-Imier, a north-south oriented valley within the Swiss , part of the at an elevation of 814 meters above . The local topography consists of folded plateaus and ridges characteristic of the Jura fold-and-thrust belt, formed during the as part of the , with prominent surrounding elevations including Mont Soleil at 1,097 meters and Mont Crosin. The underlying geology features and carbonate sequences, including and marl deposits that contribute to karstic features such as sinkholes and underground drainage in the broader Jura region. Vegetation in the area reflects the Jura's altitudinal gradient, with mixed deciduous and coniferous forests dominated by , , , , and on lower slopes, transitioning to open pastures and meadows at higher elevations used for and hay production. These high Jura pastures, often above 1,000 meters, support alpine flora adapted to cooler conditions, while the valley floor features agricultural fields interspersed with hedgerows and small woodlands. The region's natural landscape also includes rivers like the Suze, ponds, and forests that provide habitats for wildlife, though human activities such as forestry and installations— including wind turbines on Mont Crosin—have modified some areas. The of Saint-Imier is classified as humid continental (Dfb under the Köppen system), influenced by its mid-elevation position in the Jura, resulting in colder temperatures and higher than the . Average monthly temperatures range from -1°C in to 16°C in , with annual means around 7°C based on nearby station data. Winters are cold with frequent cover due to northerly winds, while summers are mild and humid; annual totals approximately 1,200-1,500 mm, distributed fairly evenly but with peaks in summer thunderstorms common to the Jura. data from simulated historical records indicate variability, with extremes including heavy snowfall in winter and occasional fog in the valley, though long-term trends show slight warming consistent with broader Swiss patterns reported by MeteoSwiss.

Historical Development

Origins and Medieval Period

The origins of Saint-Imier are rooted in the legend of Imier, a said to have arrived in the Vallon de Saint-Imier around 600 AD from the Ajoie region, where he cleared land and evangelized before dying circa 615 AD; his tomb purportedly became the nucleus of an early settlement and church. However, this account lacks contemporary documentation and represents hagiographic tradition rather than verifiable history, with the saint's emerging later. The first historical attestation of Saint-Imier appears in a 884 AD charter issued by Emperor the Fat, confirming possessions of Moutier-Grandval and referencing the "cella de sancti Himerii," interpreted as a rural , farm, and possible dedicated to Saint Imier, indicating an established site by the late . Initially under Moutier-Grandval until 999 AD, the site passed to the Bishopric of following a by King Rodolphe III of . A is noted in records from 968 AD, and archaeological excavations at the former Saint-Martin church site (conducted 1986–1990) uncovered high medieval religious structures and burials, supporting early ecclesiastical presence from the 9th–10th centuries. During the high and late medieval periods, Saint-Imier developed as a key center. The Romanesque , likely constructed in the under Basel's episcopal authority, housed Saint Imier's relics and featured a chapter of twelve canons established before 1177, evolving from an earlier monastic foundation. The is documented by 1228, possibly originating in the 9th–10th centuries. Secularly, in 1264, Otton d'Arguel transferred avouerie () rights to the of , incorporating Saint-Imier into the lordship of Erguël. By the late , it served as the "high " overseeing subordinate communities including Villeret, Sonvilier, Renan, and La Ferrière, reflecting its regional and administrative prominence.

Industrialization and Watchmaking Emergence

Watchmaking in Saint-Imier emerged in the 18th century through the decentralized établissage system, where independent home-based artisans produced components supplied and assembled by établisseurs. This cottage industry laid the groundwork for industrialization, with production in the Swiss Jura region expanding significantly from 1846 to 1873, as national output rose from 130,000 to 580,000 watches valued at 30 million francs. In 1832, Auguste Agassiz founded a workshop in Saint-Imier under the name Raiguel Jeune & Cie, specializing in pocket watches through home-based labor and central assembly. The shift to industrialized factory production began in 1866 when Ernest Francillon, Agassiz's nephew who assumed control in 1852, constructed the first centralized facility at Les —named for the adjacent "longs prés" meadows—powered by water and later steam. Inaugurated in , it employed 40 workers initially and produced the firm's first complete movements, emphasizing for precision amid growing American from mass-produced imports in the and . Following the 1876 Exhibition, technical director Jacques David's 1877 report advocated and machinery inspired by U.S. methods, accelerating adoption at , which reached 15,000 watches annually by 1874–1875. By the late , Saint-Imier's economy transformed from agriculture to industry, with watch factories proliferating; Excelsior Park, founded in 1866 by Jules-Frédéric Jeanneret, industrialized under steam power in 1889. Additional facilities like Droz & Cie (Montres Berna), Usine du Parc, Usine Centrale, and Rue des Roses emerged, forming five major operations by 1900 that employed over half the population in watchmaking. The town's population grew tenfold within 50 years, reflecting the sector's dominance and Saint-Imier's role in Swiss exports, where by 1890 half of the nation's watches and movements originated from the including Saint-Imier.

The 1872 Anti-Authoritarian Congress

The Congress of Saint-Imier, held on September 15–16, 1872, convened as a direct response to the decisions of the of the (IWA), where and his supporters had expelled , James Guillaume, and other anti-authoritarians, accusing them of promoting secret societies and splitting the organization. Delegates representing the Jura Federation (centered in the Swiss Jura mountains, including Saint-Imier), along with sections from , , , , and the , gathered to reject these expulsions and the centralizing tendencies imposed by the IWA's General Council in . The event underscored tensions between federalist, libertarian socialists—who prioritized workers' and —and those advocating hierarchical political structures to seize state power. Key figures included Guillaume (a Jura watchmaker and editor of the Bulletin de la Fédération Jurassienne), Adhémar Schwitzguébel (another Jura anarchist), and Italian delegates such as Carlo Cafiero and Errico Malatesta, who had recently joined the anti-authoritarian cause after the Hague. The congress affirmed the continuity of the IWA's original anti-authoritarian principles, as established in its 1864 founding statutes, while denouncing the Hague's "illegal" and "authoritarian" resolutions that dissolved autonomous sections and centralized control. Approximately 20–30 delegates participated, reflecting the grassroots, decentralized nature of the Jura movement, which drew heavily from skilled artisans like watchmakers radicalized by economic precarity and mutual aid traditions. The congress adopted four principal resolutions, which served as the manifesto for the emerging Anti-Authoritarian International:
  • The first rejected the Hague decisions outright, declaring them void and calling for federations to ignore the General Council's authority.
  • The second established a "Pact of Friendship, Solidarity, and Mutual Defence" among autonomous federations, emphasizing voluntary cooperation without imposed unity.
  • The third outlined the proletariat's political stance: destruction of all political power through social revolution, eschewing participation in bourgeois elections or parliaments as distractions from direct economic struggle.
  • The fourth reaffirmed the IWA's federalist structure, with sections retaining full autonomy and congresses serving as advisory bodies rather than legislative ones.
These resolutions formalized the split within the IWA, birthing the Anti-Authoritarian International, which held subsequent congresses in (1873), (1874), and (1876), influencing global anarchist networks until its dissolution amid state repression in the late . In Saint-Imier, a watchmaking hub, the event symbolized the Jura's role as a cradle of anarchist thought, where libertarian ideas intertwined with local cooperative practices, though subsequent Marxist histories often portrayed it as a factional deviation rather than a principled defense of workers' self-emancipation. The congress's emphasis on and remains a of anarchist theory, predating and contrasting with later Marxist-Leninist models of parties.

Modern History and Recent Events

Throughout the 20th century, Saint-Imier's economy continued to revolve around watchmaking, with major factories such as expanding production and facilities to meet growing demand for precision timepieces. The of the 1930s severely impacted the town's horological sector due to its heavy reliance on exports, leading to reduced output and employment across Swiss watchmaking regions including the . Post-World War II recovery saw firms like Usine Centrale in Saint-Imier resume operations, focusing on high-value components such as gold watch cases amid renewed . The from 1975 to 1985 devastated the Swiss watch industry, causing widespread bankruptcies and mergers; Saint-Imier, as a key production hub, experienced significant economic strain before stabilization through industry consolidation into groups like SSIH (later ), which absorbed in 1979. By the early 21st century, marked its 175th anniversary in 2007 with museum expansions in Saint-Imier, underscoring the town's enduring watchmaking heritage. In recent decades, Saint-Imier has diversified beyond traditional industry, incorporating projects such as wind farms and photovoltaic installations in the surrounding valley to support . A notable event occurred from July 20 to 23, 2023, when the town hosted the International Anti-Authoritarian Gathering, commemorating the 150th anniversary of the 1872 ; attracted thousands of participants with no reported disruptions, reflecting local tolerance for its anarchist historical legacy.

Demographics and Society

Population Dynamics

The population of Saint-Imier grew rapidly during the , multiplying approximately ninefold between 1800 and 1890 as the local economy shifted from to industry, particularly lace-making and watchmaking, bolstered by and infrastructure like the 1874 railway. This expansion drew migrant workers from across , with watch factories employing over half the residents by 1900. The following decades saw a peak of 7,455 inhabitants in 1900, followed by declines linked to watch industry crises in the and , reducing the figure to 4,807 by 2000.

Recent trends indicate stabilization with modest net growth of over 10% since 1999, reaching 5,088 residents in 2023 amid economic diversification into and medical fields, though annual changes remained near-flat in 2023. Foreign nationals comprise roughly 24-29% of the population, underscoring migration's role in offsetting low natural increase typical of Swiss municipalities.

Linguistic and Ethnic Composition

Saint-Imier exhibits a predominantly Francophone linguistic profile, consistent with its position in the French-speaking Bernese Jura district of the Canton of Bern. Official linguistic surveys indicate that French serves as the principal language for approximately 85.2% of residents, underscoring the municipality's alignment with the broader Romandie cultural sphere despite the canton's majority German-speaking character. German follows as the second most common main language, spoken by about 7.5% of the population, while other languages, including Italian and miscellaneous others, account for the remainder, such as 1.1% and 1.5% respectively. This distribution has remained stable over recent decades, with minimal shifts attributable to the region's entrenched linguistic traditions and limited internal migration pressures. Ethnically, the population is overwhelmingly of Swiss origin, with Swiss nationals comprising the majority alongside a notable foreign resident component driven by the local watchmaking industry's historical labor demands.
