The Philippine–American War, known alternatively as the Philippine Insurrection, Filipino–American War, or Tagalog Insurgency, was fought between the First Philippine Republic and the United States from February 4, 1899, until July 2, 1902. Tensions arose after the United States annexed the Philippines under the Treaty of Paris at the conclusion of the Spanish–American War rather than acknowledging the Philippines' declaration of independence. The war can be seen as a continuation of the Philippine struggle for independence that began in 1896 with the Philippine Revolution against Spanish rule.

The Treaty of Peace between the United States of America and the Kingdom of Spain, commonly known as the Treaty of Paris of 1898, was signed by Spain and the United States on December 10, 1898, that ended the Spanish–American War. Under it, Spain relinquished all claim of sovereignty over and title to territories described there as the island of Porto Rico and other islands now under Spanish sovereignty in the West Indies, and the island of Guam in the Marianas or Ladrones, the archipelago known as the Philippine Islands, and comprehending the islands lying within the following line:, to the United States. The cession of the Philippines involved a compensation of $20 million from the United States to Spain.
