Philippine-American War Memorial Day is observed on February 4 each year, commemorating the conflict between the United States and Filipino revolutionaries that began in 1899. This day can be seen as a continuation of the Philippines' struggle for independence, which was initially sparked by the transfer of jurisdiction from Spain to the United States following the Spanish-American War. Filipino leaders, who had control over most of the archipelago, resisted U.S. attempts to annex the Philippines, leading to the Philippine-American War. The conflict officially ended in 1902, but sporadic combat continued for several years. The U.S. maintained control over the Philippines until 1946, except during World War II. Observances of this day may include educational activities, discussions about the historical significance of the war, and reflections on the impact of U.S. colonial rule in the Philippines.
