On 1590, the population of Pangasinan and started to settle Nueva Ecija and increase as well, the flood that continued to happen in Pangasinan would cause a part of the population of Pangasinan to go to Nueva Ecija, Ituy and Bulacan, the population of the settlers would increase.
The population of Pangasinan would become loyal to the Spanish in the same way as the people of Pampanga are.
The parts of the area of the Kumintang Province would be fiercely Moro and the Spanish would have difficulties conquering parts of it, which would later .
After the Gaddang revolt in the early 17th century, the areas decimated by the Spanish were settled by immigrants from Pangasinan, the same thing happened in the Ladia revolt where in the people from Pangasinan.
The Almazan and Maniago revolts started in 1650, however the Pangasinense would not join the revolt because the Spanish changed their own stance to the Pangasinenses and that the Spanish would favor them in the foreseeable future, the Ilocanos and Kapampangans would revolt.
“The Maniago Revolt was an uprising in Pampanga during the 1660s. It was a revolt against the Spanish during the colonial period and was named after its leader, Francisco Maniago. During that time, Pampanga drew most of the attention from the Spanish religious Orders because of its relative wealth. They also bore the burden of more tribute, forced labor, and rice exploitation. They were made to work for eight months under unfair conditions and were not paid for their labor and for the rice purchased from them. Their patience was put to the limit and they signified their intention to revolt by setting their campsite on fire. The fight soon began and because the Spaniards were busy fighting against the Dutch, they were badly depleted by the Kapampangans. The Maniago revolt was the start of a much bigger and even bloodier revolt in Ilocos. This battle was led by a man named Pedro Almazan who had heeded the call of Maniago to revolt against the Spaniards.
A part of the chain to the Maniago Revolt was the Ilocos Revolt led by Don Pedro Almazan, illustrious and wealthy leader from San Nicolas, Laoag, Ilocos Norte. The letters sent by Don Francisco Maniago narrating the defeat of the Spaniards in his area and urging other provinces to rise in arms failed to obtain any support among the natives. During the revolt, Don Pedro Almazan proclaimed himself "King of Ilocos", but was later captured and executed. He also had a son which the Ilocanos proclaimed their prince.“
