It had a population of 1,503,456 people according to the 2020 census. Its capital is the city of Tarlac, which is the most populous in the province. It is bounded on the north by the province of Pangasinan, Nueva Ecija on the east, Zambales on the west, and Pampanga in the south. The province comprises three congressional districts and is subdivided into 17 municipalities and one city, Tarlac City, which is the provincial capital.

The province is situated in the heartland of Luzon, in what is known as the Central Plain also spanning the neighbouring provinces of Pampanga, Pangasinan, Nueva Ecija, and Zambales. Tarlac covers a total land area of .

Early in history, what came to be known as Valenzuela Ranch today was once a thickly forested area, peopled by roving tribes of nomadic Aetas who are said to be the aboriginal settlers of the Philippines, and for a lengthy period, it was the remaining hinterland of Luzon's Central Plains. Today, Tarlac is one of the most multi-cultural provinces in the region for having a mixture of four distinct ethnic groups: the Kapampangans, the Pangasinans, the Ilocanos, and the Tagalogs. It is also known for its fine food and vast sugar and rice plantations in Central Luzon.

History

Spanish colonial era

Tarlac's name is a Hispanized derivation from a talahib weed called tarlak, an Aeta term. The area around the current capital city was described as matarlak or malatarlak, a word meaning "abundant with tarlak grass."Resources for Local Governance – Tarlac Tarlac was originally divided into two parts: the southern division belonging to Pampanga and the northern division belonging to Pangasinan; the province was named after the present capital city. It was the last province in Central Luzon to be organized under the Spanish colonial administration in 1874. Its nucleus were the towns of Concepcion, Capas, Bamban, Mabalacat, Magalang, Porac, Floridablanca, Victoria, and Tarlac which constituted a military comandancia. Some of these municipalities were returned to Pampanga but the rest were incorporated into the new province of Tarlac.

Unlike other provinces in Central Luzon, Tarlac was relatively free from revolts during the Spanish regime before the late 1800s rose. Only the rebellion started by Juan de la Cruz Palaris in Pangasinan spread to the northern portion of Tarlac.

Philippine revolution During the Philippine Revolution of 1896, Tarlac was among the first eight provinces to rise against Spain, alongside neighbouring Pampanga. It became the new seat of the first Philippine Republic in March 1899 when General Emilio Aguinaldo abandoned the former capital, Malolos, Bulacan. This lasted only for a month before the seat was moved to Nueva Ecija in Aguinaldo's attempt to elude the pursuing Americans.

American colonial era On October 23, 1899, Gregorio Aglipay, military vicar general of the revolutionary forces, called the Filipino clergy to a conference in Paniqui. There, they drafted the constitution of the Philippine Independent Church. They called for the Filipinization of the clergy, which eventually led to a separation from the Roman Catholic Church in the Philippines.

Tarlac was captured by American forces in November 1899. A civil government was established in the province in 1901.

Japanese occupation During World War II, Camp O'Donnell in Capas became the terminal point of the infamous Bataan Death March of Filipino and American soldiers who surrendered at Bataan on April 9, 1942. Many prisoners died of hunger, disease and/or execution. The general headquarters of the Philippine Commonwealth Army was established from January 3, 1942, to June 30, 1946, and the 3rd Constabulary Regiment of the Philippine Constabulary was founding again from October 28, 1944, to June 30, 1946, and military stationed in the province of Tarlac and some parts in Central Luzon due to Japanese occupation. Local troops of the Philippine Commonwealth Army units sent the clearing military operations in the province of Tarlac and Central Luzon from 1942 to 1945 and aided them by the recognized guerrilla groups including Hukbalahap Communist fighters and attacking Japanese Imperial forces. But in the aftermath, some local guerrilla resistance fighters and Hukbahalap groups became retreating Imperial Japanese troops around the province and before the liberation from the Allied forces.

In early 1945, combined American and Filipino military forces with the recognized Aringay Command guerrillas liberated Camp O'Donnell. The raid in Capas resulted in the rescue of American, Filipino and other allied Prisoners of War.

From January 20, 1945, to August 15, 1945, Tarlac was recaptured by combined Filipino and American troops together with the recognized guerrilla fighters against the Japanese Imperial forces during the liberation and beginning for the Battle of Tarlac under the Luzon Campaign.

Postwar era After the social and economic upheavals of the war and with government institutions still in their nascent form after the recognition of Philippine Independence by the international community, the first few decades after the end of the war were marked by dissatisfaction and social tension. In the largely agricultural context of Central Luzon and Tarlac those tensions tended to coalesce around the interrelated issues of land ownership, and the working conditions of agricultural workers.

The Filipino communist Hukbalahap guerrilla movement formed by the farmers of Central Luzon to fight the Japanese occupation, had found themselves sidelined by the new post-independence Philippine government which had taken up the fear of communist influence which marked the beginning of the cold war in the west. So they decided to extended their fight into a rebellion against the new government, only to be put down through a series of reforms and military victories by Defense Secretary, and later President, Ramon Magsaysay.Jeff Goodwin, No Other Way Out, Cambridge University Press, 2001, p.119, ,

Ultimately more effective than those who took up arms were the numerous political and labor movements who kept working towards agricultural land reform and stronger labor rights, with laborers' and farmers' protests gathering enough steam that several Philippine presidents were forced to meet with them and then concede to their demands. Among the most successful of these were the Land Justice March of the political group known as the Filipino Agrarian Reform Movement (FARM), which intended to march from Tarlac to Malacañang in 1969, although President Marcos was forced to give in to their demands early, meeting them while they were still at Camp Servillano Aquino in Tarlac City itself.

Martial law era The beginning months of the 1970s marked a period of turmoil and change in the Philippines, as well as in Tarlac. 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 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.

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. This period in Philippine history is remembered for the Marcos administration's record of human rights abuses, particularly targeting political opponents, student activists, journalists, religious workers, farmers, and others who fought against the Marcos dictatorship. At least two major military camps in Tarlac were used as detention centers for political detainees in Tarlac: Camp Servillano Aquino and Camp Macabulos, both in Tarlac City.Panaglagip: The North Remembers – Martial Law Stories of Struggle and Survival Edited by Joanna K. Cariño and Luchie B. Maranan. They were part of Regional Command for Detainees II (RECAD II) and administered under Camp Olivas in Pampanga.

Martial Law had immediate political impacts in Tarlac, since political leaders who were critical of Marcos were immediately jailed. This included Senator and Concepcion native Ninoy Aquino, and Bamban Mayor Pedro D. Mendiola who was imprisoned in Camp Crame. Other Tarlaqueño Marcos critics who had roles in government, such as Development Academy of the Philippines (DAP) executive vice president Horacio Morales, tried to stay so they could pursue change from within, but eventually could not reconcile themselves with the idea of working within the dictatorship. Ordinary Tarlaqueños also resisted the dictatorship. Former Seminarian Teresito Sison campaigned for the rights of teachers, farmers, and of laborers in Clark Air Base, but torture during two stints in Marcos' detention centers caused a decline in his health until he died in 1980. Tarlaqueno activists decided to take up arms against the dicgtatorhip, including Eduardo Aquino, Merardo Arce, and Benedicto Pasetes were killed in various encounters with Marcos' forces.

Ninoy Aquino was eventually assassinated in August 1983, igniting protests throughout the Philippines which would eventually force Marcos to announce a snap election in February 1986. Even then, those who resisted Marcos were targeted for death, such as in the case of oppositionist campaign organizer Jeremias De Jesus political organizer, who was assassinated shortly before the elections

Geography

The landlocked province is situated at the center of the central plains of Luzon, landlocked by four provinces: Pampanga on the south, Nueva Ecija on the east, Pangasinan on the north, and Zambales on the west. The province covers a total area of . Approximately 75% of the province is plains while the western side is hilly to slightly mountainous.

The province includes a large portion of mountains like Mt. Telakawa (Straw Hat Mountain), located at Capas, Tarlac. Mt. Bueno, Mt. Mor-Asia and Mt. Canouman are also located in Capas as well as Mt. Dalin. The other mountains are Mt. Dueg and Mt. Maasin, found in the municipality of San Clemente. Also noted are Mt. Damas of Camiling. A portion of Mount Pinatubo (whose summit crater rests in neighbouring Zambales) also rests in Bamban and Capas. The whole of Mayantoc and San Jose are mountainous so it is suitable for the highest natural resources and forest products in the province such as coal, iron, copper, temperate-climate fruits and vegetables, fire logs, sand, rocks and forest animals such as wild boar and deer. The main water sources for agriculture include the Tarlac River at Tarlac City, the Lucong and Parua rivers in Concepcion, Sacobia-Bamban River in Bamban and the Rio Chico in La Paz.

Administrative divisions Tarlac is subdivided into 17 municipalities and one component city, all encompassed by three congressional districts. There are a total of 511 barangays comprising the province.
