Nationalism refers to devotion and loyalty to one's own country, and the desire for national advancement or political independence. Filipino nationalism arose due to several factors, including resisting forced labor, oppressive tribute systems, and the seizure of lands by Spanish friars. This led to numerous revolts across the Philippines between the 16th and 19th centuries. Some of the major revolts included the Dagami Revolt in 1565-1567 in Leyte, the Tagalog Revolt in 1574 in Tondo, and the Dagohoy Revolt from 1744-1829 in Bohol, which was the longest revolt. Many revolts were in response to Spanish colonial abuses and the imposition of Catholicism.
