Philippine–American War

Lore & Background

The war originated from the U.S. annexation of the Philippines under the Treaty of Paris (December 1898), which ended the Spanish–American War. Philippine nationalists, who had declared independence in June 1898 and formed the First Philippine Republic in January 1899, were excluded from the treaty negotiations. Tensions escalated into open combat on February 4, 1899, during the Battle of Manila. After a failed armistice request, the Philippine government issued a proclamation on June 2, 1899, urging continued resistance. Philippine forces initially fought conventionally but shifted to guerrilla tactics by November 1899.

The Philippine–American War marked a pivotal moment in U.S. overseas expansion and sparked domestic anti-imperialist backlash, with critics arguing it contradicted the principles of the Declaration of Independence. The war resulted in at least 200,000 Filipino civilian deaths, largely from famine and disease, including a cholera epidemic. U.S. forces employed scorched earth campaigns, reprisals, and concentration camps, leading to thousands of additional deaths. The conflict led to cultural changes in the Philippines, including the rise of Protestantism, disestablishment of the Catholic Church, and adoption of English as the primary language of government and education. The U.S. Congress passed the Philippine Organic Act (1902), the Jones Act (1916), and the Tydings–McDuffie Act (1934), gradually increasing self-governance and setting a path to independence, which was achieved in 1946 after World War II and Japanese occupation.
