The recorded military history of Puerto Rico encompasses the period from the 16th century, when Spanish conquistadores battled native Taínos in the rebellion of 1511, to the present employment of Puerto Ricans in the United States Armed Forces in the military campaigns in Afghanistan and Iraq. Puerto Rico was part of the Spanish Empire for four centuries, during which the people of Puerto Rico defended themselves against invasions from the British, French, and Dutch. Puerto Ricans fought alongside General Bernardo de Gálvez during the American Revolutionary War in the battles of Baton Rouge, Mobile, Pensacola and St. Louis. During the mid-19th century, Puerto Ricans residing in the United States fought in the American Civil War. In the 1800s, the quest for Latin American independence from Spain spread to Puerto Rico, in the short-lived revolution known as the Grito de Lares and culminating with the Intentona de Yauco. The island was invaded by the United States during the Spanish–American War. After the war ended, Spain officially ceded the island to the United States under the terms established in the Treaty of Paris of 1898. Puerto Rico became a United States territory and the "Porto Rico Regiment" (Puerto Rico's name was changed to Porto Rico) was established on the island. Upon the outbreak of World War I, the U.S. Congress approved the Jones–Shafroth Act, which extended United States citizenship (the Puerto Rican House of Delegates rejected US citizenship) with limitations upon Puerto Ricans and made them eligible for the military draft. Since then, as citizens of the United States, Puerto Ricans have participated in every major United States military engagement. During World War II, Puerto Ricans participated in the Pacific and Atlantic theaters, not only as combatants but also as commanders. It was during this conflict that Puerto Rican nurses were allowed to participate as members of the WAACs. Four Puerto Ricans were awarded the Medal of Honor, the highest military honor in the United States, for their actions during the Korean War. The members of Puerto Rico's 65th Infantry Regiment distinguished themselves in combat in the Korean War and were honored with the Congressional Gold Medal. During the Vietnam War five Puerto Ricans were awarded the Medal of Honor. Presently, Puerto Ricans continue to serve in the military of the United States.
