Once occupying a vast stretch of land that extended from Tondo[3] to the rest of Central Luzon, huge chunks of territories were carved out of Pampanga so as to create the provinces of Bulacan, Bataan, Nueva Ecija, Aurora and Tarlac.
They even speak other languages within the environment of other ethnic groups in areas they settled and grew up in, like Sambal, Pangasinan, Ilocano, and Tagalog (all in Central Luzon).
According to Bruneian folklore, at around 1500 Sultan Bolkiah launched a successful northward expedition to break Tondo’s monopoly as a regional entrepot of the Chinese trade and established Maynila (Selurong?)
[13] Subsequently, Bruneian influence spread elsewhere around Manila Bay, present-day Batangas, and coastal Mindoro through closer trade and political relations, with a growing overseas Kapampangan-Tagalog population based in Brunei and beyond in Malacca in various professions as traders, sailors, shipbuilders, mercenaries, governors, and slaves.
Many Kapampangans joined a group of stronghold soldiers that survived the invasion and officially trained under the 31st Infantry Division, Philippine Commonwealth Army.
Many Kapampangan guerrillas and Hukbalahap communist groups fought for more than three years of insurgency during the Japanese Occupation and also fought side by side with allied forces in the main province of Pampanga, helping local troops of the Philippine Commonwealth Army and incoming Philippine Constabulary 3rd Constabulary Regiments stationed at the general headquarters in Pampanga in operations in Central Luzon from 1942 to 1945 against the Imperial Japanese troops.
They start the battle in Ugtung-aldo or afternoon and they end it in Sisilim or sunset with the tune of what Macabebeanons and Masantuleñios called BATTALA Masantol, Macabebe and Lubao.
The Pistang Danum of the barrios of Pansinao, Mandasig, Lanang and Pasig in Candaba, where food is served on floating banana rafts on the waters of the Pampanga River was originally a non-Christian holiday that is now made to coincide with the baptism of Christ.
The Kapampangan New Year or Bayung Banwa that welcomes the coming of the monsoons and the start of the planting season is made to coincide with the feast of John the Baptist.
The colourful Apung Iru fluvial procession of Apalit, once a thanksgiving celebration in honour of the river, has become the feast of Saint Peter.
Some popular Kapampangan dishes that have become mainstays across the country include sisig, kare-kare, tocino or pindang and their native version of the longaniza.
Other Kapampangan dishes, which are an acquired taste for the other ethnic groups include buru (fish fermented in rice), betute tugak (stuffed frogs), arobung kamaru (mole crickets sauteed in vinegar and garlic), estofadong barag (spicy stewed monitor lizard), sisig, kalderetang asu (spicy dog stew), sigang liempu, dagis a tinama (marinated rats), laman panara and bobotu.
However, traces of native-Austronesian Anitism, Hinduism, and Buddhism can still be found among their folk practices and traditions, as these were the majority beliefs of the Kapampangan before the imposition of Christianity in the 16th century.
[26] The Kapampangans have produced many Rajahs, Datus, four Philippine presidents, three chief justices, a senate president, the first Filipino cardinal, one Huk Supremo, many Huk Commanders and NPA cadres and many notable figures in public service, education, religion, diplomacy, journalism, the arts and sciences, entertainment and business.
