The first inhabitants of the Bataan peninsula are the Ayta Magbeken people. The next group of inhabitants were Kapampangans, who settled on eastern Bataan.^[4]

Later on, Tagalogs from southern Luzon, most specifically Cavite, migrated to parts of Bataan. The Ayta Magbeken migrated towards the mountain areas of Bataan by the end of the 16th century.^{[citation needed]}

In 1647, Dutch naval forces landed in the country in an attempt to seize the islands from Spain. The Dutch massacred the people of Abucay in Bataan.^{[citation needed]}

Historian Cornelio Bascara documents that the province of Bataan was established on 11 January 1757, by Governor-General Pedro Manuel Arandia out of territories belonging to Pampanga and the corregimiento of Mariveles which, at that time, included Maragondon across Manila Bay.^[5][6] Tagalogs migrated to east Bataan, where Kapampangans assimilated to the Tagalogs. Kapampangans were displaced to the towns near Pampanga by that time, along with the Aetas. By the end of the 1700s, Bataan had 3,082 native families and 619 Spanish Filipino families.^{[7]: 539 [8]: 31, 54, 113}

Bataan featured prominently during World War II. Prior to the 1941 Japanese invasion, Bataan was a military reservation for the purpose of defending the fortress island of Corregidor.^[9] The US Army stored nearly 1,000,000 US gallons (3,800 m³) of gasoline there, along with various munitions. At the southern tip of the peninsula the U.S. Navy had established a small base at the port of Mariveles.

Shortly after the Japanese Army invaded the country in December 1941, the combined US and Filipino forces were being gradually overrun and General Douglas MacArthur moved his troops to the Bataan Peninsula in an attempt to hold out until a relief force could be sent from the US. Japanese forces started a siege of the peninsula on 7 January 1942, and launched an all-out assault on 3 April, a few months after the Battle of the Points, Battle of the Pockets, the attack down Trail Number Two, and a half-dozen other brutal battles.^[10] The Bataan campaign was the last time a regular cavalry unit of the U.S. Army, the Philippine Scouts 26th Cavalry, was used as a horse mounted fighting unit. On the morning of 16 January 1942, Lt. Edwin Ramsey led the last cavalry charge into the town of Morong, routing the advancing Japanese infantry.^[11] As the troops on Bataan were continually reduced in rations, the horses were eventually slaughtered to feed the starving soldiers.^[12]

The majority of the American and Filipino forces surrendered on 9 April and were forced to march more than 100 kilometers (62 mi) from Bataan to Capas, Tarlac, which became known as the Bataan Death March.

Postwar reconstruction in the province of Bataan was generally slow, although there were efforts to pursue industrialization projects in the area, most notably the establishment of the NASSCO (National Shipyard and Steel Corporation) in Mariveles which was inaugurated in 1953 during the Quirino administration.^[13] It would later be bought by the Bataan Shipping and Engineering Company in 1964.^[14]

The beginning months of the 1970s marked a period of turmoil and change in the Philippines, as well as in Bataan.^[15][16] During his bid to be the first Philippine president to be re-elected for a second term, Ferdinand Marcos launched an unprecedented number of foreign debt-funded public works projects. This caused^[17][18] the Philippine economy took a sudden downwards turn known as the 1969 Philippine balance of payments crisis, which in turn led to a period of economic difficulty and a significant rise of social unrest.^{[19][20][21][22]: "43"}

Just as this was happening, it was revealed that the site of two communities where the workers of NASSCO lived - Barrio NASSCO and Barrio Camaya - would be torn down for conversion into the new Bataan Export Processing Zone in 1969, compelling the relocation of the residents who in turn launched protests until the BEPZ was finally built in 1972.^[23]

With only a year left in his last constitutionally allowed term as president, Ferdinand Marcos placed the Philippines under Martial Law in September 1972 and thus retained the position for fourteen more years.^[24] This period in Philippine history is remembered for the Marcos administration's record of human rights abuses,^[25][26] particularly targeting political opponents, student activists, journalists, religious workers, farmers, and others who fought against the Marcos dictatorship.^[27]

By this time, the social unrest of the pre-martial law period and the Marcos' violent responses to the protests of the time led many of the Philippines' youth, who previously held moderate positions calling for political reform, to be radicalized. Some were convinced to joined the newly-formed New People's Army as a last desperate way to resist Marcos' authoritarianism,^[28][29] including Catalino Blas, Amado Bugay, and Delia Cortez, who were all idealistic activists killed in encounters with Marcos' forces in various locations in Bataan.^[30][31][32] But many noncombatants were killed as well, such as Social Worker and Catholic lay worker Puri Pedro, who had been wounded as part of the collateral damage during one encounter in 1977, but was assassinated in cold blood by a soldier who identified himself as Col. Rolando Abadilla while she was recovering at the Bataan Provincial Hospital.^[33][34]

It was also during Martial Law that construction on the Bataan Nuclear Power Plant began in Morong, in 1976.^[35] Marcos had announced an intention to build a nuclear power plant in July 1973, not long after the declaration of Martial Law,^[35] and a presidential committee was set up to review proposals, of which there were two - one each from General Electric and Westinghouse Electric. The committee preferred the proposal of General Electric's bid although it cost more, because it contained detailed specifications for the plant. But Marcos, in a deal brokered by crony Herminio Disini, overrode then and signed a letter of intent awarding the project to Westinghouse, despite the absence of any specifications on their proposal.^[36] The project was plagued with problems throughout construction, including location, welding, cabling, pipes and valves, permits, and kickbacks, as well as setbacks such as the decline of Marcos's influence due to bad health and PR fallout from the incident at the Three Mile Island nuclear reactor.^[37] A subsequent safety inquiry into the plant revealed over 4,000 defects.^[35] Another issues raisead regarding it was the proximity of a major geological fault line and of the then-dormant Mount Pinatubo.^[36] By March 1975, Westinghouse's cost estimate ballooned to US$1.2 billion without much explanation. The final cost was $2.2 Billion for a single reactor producing half the power of the original proposal.^[36] Many problems identified in earlier stages remained throughout construction, as reported by inspectors though denied by Westinghouse.^[37] The power plant was responsible for generating 10% of the country's external debt, despite never actually operating.^[38]

On 14 March 2020, Bataan recorded one of the earliest cases of COVID-19 infection outside of Metro Manila, with a male patient from Orani being the 64th recorded case in the Philippines.^[39] Bataan later became one of the provinces under the Enhanced community quarantine in Luzon.^[40][41]

Bataan lies in the southwestern part of the Central Luzon region. It is a peninsular province with an area of 1,372.98 square kilometers (530.11 sq mi)^[42]. The province is bounded in the west by the South China Sea, in the south by the Corregidor Island, and in the east by Manila Bay - the gateway to the Philippines' political, social and economic center. It is bounded inland by the city of Olongapo in the north and by the provinces of Pampanga and Bulacan in the northeast. Its capital, the City of Balanga, is about 31.3 nautical miles from Manila across Manila Bay.^[43]

Bataan, a peninsula, is composed of 11 municipalities and one city. All except the northernmost municipality of Dinalupihan, are coastal areas. The province's coastline is approximately 177 kilometers from Hermosa in the northeastern portion of the province, looping up to Morong in the northwest.

Bataan is divided by two mountain groups of volcanic origins. The northern side is composed of the Mount Natib (elevation 1,253 meters (4,111 ft)), Mount Sta. Rosa and Mount Silangan. The southern group is composed of Mount Mariveles, Mount Samat, and Mount Cuyapo. A narrow pass separates these two mountain groups.^[6] The topography of the province is classified generally as hilly and mountainous with a narrow plain on the eastern side. The highest elevation is in the Mariveles mountains at 1,388 meters above sea level.^[43]

Bataan has abundant water resources in the form of rivers, streams, creeks, waterfalls and springs. There are more than 100 rivers in the province radiating from the two aforementioned mountain groups. These are important not only for irrigation but also for navigation and fishing as well. The Talisay and Almacen Rivers are the two major rivers in the province. Talisay has its headwater in the Mariveles mountain group extending down to Pilar and Balanga into Manila Bay. Almacen River has its headwater in the Natib mountains extending down to Hermosa and exits through the Orani Channel to Manila Bay. Some of the smaller rivers are Abo-abo River, Bantalan River, Lamao River, Saysayin River, Agloloma River, Mamala River.^[43]

Muddy tidal flats along the alluvial sandbars characterize the coastline along Manila Bay. Mangrove areas can be observed from Orani to Orion, along with seaweed areas and seagrass patches areas from portions of Balanga and Pilar down to Mariveles. The deeper portions are the coastal areas of Orion to Mariveles where most seaports are operating. Poor coral reef patches, mixed with sandy-rocky bottom can be found in Mariveles area, where the coastline begin to take on a rocky character looping from the mouth of Manila Bay to the western side of the province. The coastline facing the South China Sea is interspersed with pristine beaches with rocky portions and fringes of coral reef in good condition from Bagac to Morong, which is a haven for sea turtles and other marine animals.^[43]

Bataan has distinct dry and wet seasons categorized as Type I in the Philippines' Modified Coronas' Climate Classification (Climate of the Philippines). The dry season begins in November and ends in April, while the rainy season starts in May and ends in October. The most rains come in June to August. Mean average rainfall in August is the heaviest at 633mm. Bataan is often visited by typhoons. Farming systems in the province follow these climatic cycles.^[43]

Bataan is administratively subdivided into 11 municipalities and one component city.

Republic Act (RA) No. 11964, otherwise known as the “Automatic Income Classification of Local Government Units Act”, was signed by the Philippine President Ferdinand “Bongbong” Marcos Jr. on October 26, 2023.^[45][46] The law classifies municipalities and cities into five (5) classes, according to their income ranges, based on the average annual regular income for three fiscal years preceding a general income reclassification.^[47][48] The classifications are as follows:

Kapampangan is spoken in towns near the boundary with Pampanga, specifically Dinalupihan, Hermosa, and Orani. Ilocano is spoken by descendants of Ilocano settlers in southeastern areas, specifically Orion, Limay, and Mariveles.^{[51][52][better source needed]}.

The three most prominent ethnic groups in Bataan are the Tagalogs, the Kapampangans and the Ayta Magbeken, though the third group has a lower population despite being the province's first inhabitants. The second group is mainly present at the northeast of the province, as well as in the provincial capital to a lesser extent. Some Bataeños are descendants of Ilocano settlers. Non-native residents in Bataan include Pangasinans, Bicolanos, several Cordillera tribes, Cebuanos, Hiligaynons, Maranaos, Maguindanaons and Tausugs.

Bataan is one of the most progressive provinces of Luzon and Manila Bay Region, and a key contributor to the region's overall economic productivity. Its 2024 Provincial Product Account (PPA) also known as Provincial GDP (Gross Domestic Product) stands at PhP300-billion. It registered a growth rate of 9.3% which is the fastest in Central Luzon region. Also, the Philippine Statistics Authority estimates that Bataan leads all other provinces in the Philippines in terms of per capita GDP at PhP 337,218. The 2024 per capita GDP is derived by dividing the GDP of the province/ HUC by its total population based on the 2024 Census of Population (2024 POPCEN).^[55][56] The province is strategically located right in the middle of the country's growth triad corridor of Subic Special Economic and Freeport Zone, Clark Freeport and Special Economic Zone and Metro Manila. It is one of the Philippines' industrial centers owing to the presence of heavy industries, two freeport zones and several special manufacturing zones. Due to these factors plus the province's competitive incentives offered to new business locators, the Philippine Chamber of Commerce and Industry adjudged Bataan as the most business friendly province in the country during the 49th Philippine Business Conference Expo held last 25 and 26 October 2023. This is the third time the province had received such recognition, the first one was in 2018, while the second in 2021.^[57]

In 2020, Bataan registered the third highest locally sourced income among all the provinces in the Philippines as certified by the Department of Finance - Bureau of Local Government Finance (BLGF).^[58]

Bataan is a location of bulk power generation, where most of the power generated is sent to the Luzon Grid. Most power plants in Bataan rely on fossil fuels, like oil and coal, but renewable energy sources, primarily solar power, form part of the total generation. As of 30 November 2022 the total installed capacity of existing power plants equals to 3,676.7 MW.^[84] Incoming power plants that are under construction will increase the output to 4,920.7 MW, with targeted commissioning date of 3rd quarter, 2023 to 3rd quarter, 2026.^[85]

Fossil fuel-fired plants account for 3,528 MW, and are mostly concentrated in Limay and Mariveles. These include the GN Power Mariveles Coal Power Plant, with 690 (2x345) MW, SMC Limay Greenfield Power Plant (4x150 MW), Petron Cogeneration Power Plant (4x35 MW), Panasia Bataan Combined Cycle Power Plant (648 MW), and the recently commissioned GN Power Dinginin Units 1 and 2 (725x2 MW).^[84][86] Two plants are under construction, Petron's Refinery Solid Fuel-Fired Boiler Project - Phase 3 (44 MW), and SMC Mariveles Coal Power Plant (8x150 MW). These will increase the capacity by additional 1,244 MW.^[85] Three natural gas-fired power plants with combined capacity of 3,275 MW are proposed, one planned in Limay and two in Mariveles.
