Region 1 was first
inhabited by the aboriginal Negritos before they were pushed by successive
waves of Malay/Austronesian immigrants that penetrated the narrow coast.
Tingguians in the interior, Ilocanos in the north, and Pangasinense in the
south settled the region.
From the data on
the population distribution of Region 1, it is clear that not all the
inhabitants are Ilocanos. Around one-third are non-Ilocanos and yet there is a
popular misconception that all the inhabitants are Ilocanos. The use of the term
Ilocos Region promotes the wrong notion that all the residents of Region 1 are
Ilocanos. Before the administration of Ferdinand Marcos, Pangasinan was not a
part of the region.
The Spanish
arrived in the 16th century and established Christian missions and governmental
institutions to control the native population and convert them to the Roman
Catholic Church. Present-day Vigan City in Ilocos Sur province became the
bishopric seat of Nueva Segovia. Ilocanos in the northern parts were less
easily swayed, however, and remained an area filled with deep resentments
against Spain. These resentments bubbled to the surface at various points in
the Ilocos provinces' history as insurrections, most notably that of Andres
Malong and Palaris of Pangasinan, Diego Silang and his wife Gabriela Silang in
1764, and the Basi Revolt in the 19th century. However, it was the
Pangasinenses in the south who were the last to be stand against the Spaniards.
In 1901, the
region came under American colonial rule, and in 1941, under Japanese
occupation.
During 1945, the
combined American and the Philippine Commonwealth troops including with the
Ilocano and Pangasinese guerillas liberated the Ilocos Region from Japanese
forces during the Second World War.
Several modern
presidents of the Republic of the Philippines hailed from the Region: Elpidio
Quirino, Ferdinand Marcos, and Fidel V. Ramos.
Before the
formation of the Cordillera Administrative Region, Region 1 also included the
provinces of Abra, Mountain Province, and Benguet. Before Region 1 was modified
by Ferdinand Marcos,Pangasinan was not part of the region.
