Puerto Rican citizenship
On April 12, 1900, the United States Congress enacted the Foraker Act of 1900, which replaced the governing military regime in Puerto Rico with a civil form of government. Section VII of this act created a Puerto Rican citizenship for the residents "born in Puerto Rico and, therefore, subject to its jurisdiction." The Puerto Rican citizenship replaced the Spanish citizenship that Puerto Ricans held at the time in 1898. Such Puerto Rican citizenship was granted by Spain in 1897. This citizenship was reaffirmed by the United States Supreme Court in 1904 by its ruling in which denied that Puerto Ricans were United States citizens and labeled them as noncitizen nationals. In a 1914 letter of refusal to the offer of U.S. citizenship and addressed to both the President of the United States and the U.S. Congress, the Puerto Rico House of Delegates stated ""We, Porto Ricans, Spanish-Americans, of Latin soul ... are satisfied with our own beloved Porto Rican citizenship, and proud to have been born and brethren in our own motherland."" The official 1916 Report by the American colonial governor of Puerto Rico to the U.S. Secretary of War (the former name for the Department of Defense), addresses both citizenships, the Puerto Rican citizenship and United States citizenship, in the context of the issuance of passports, further evidencing that the Puerto Rican citizenship did not disappear when the Americans took over the island in 1898.
Puerto Ricans in World War II
Puerto Rico was annexed by the United States in accordance to the terms of the Treaty of Paris of 1898, ratified on December 10, 1898, as consequence of the Spanish–American War. U.S. Citizenship was imposed upon Puerto Ricans as a result of the 1917 Jones-Shafroth Act (the Puerto Rican House of Delegates rejected US citizenship) and were expected to serve in the military. When an Imperial Japanese Navy carrier fleet launched an unexpected attack on Pearl Harbor on December 7, 1941, Puerto Ricans were required to bear arms in defense of the United States. During World War II, it is estimated by the Department of Defense that 65,034 Puerto Ricans served in the U.S. military. Most of the soldiers from the island served in either the 65th Infantry Regiment or the Puerto Rico National Guard. As the induction of Puerto Ricans into the armed forces increased many were assigned to units in the Panama Canal Zone and the British West Indies to replace the continental troops serving in regular Army units. Those who resided in the mainland of the United States were assigned to regular units of the military. They were often subject to the racial discrimination that was widespread in the United States at the time.
