# The Chronicle of Puerto Rico: Borikén of the Taíno, four centuries a Spanish stronghold of the Indies, now a self-governing Commonwealth of the United States poised between the questions of statehood, independence, and the status quo. History of Puerto Rico: Borikén of the Taíno, four centuries a Spanish stronghold of the Indies, now a self-governing Commonwealth of the United States… Canonical: https://terralore.co/country/PRI/chronicle Updated: 2026-06-15 Founding: Commonwealth (Estado Libre Asociado) Established — 25 July 1952. On 25 July 1952 Governor Luis Muñoz Marín proclaimed the Constitution of the Commonwealth of Puerto Rico, in Spanish the Estado Libre Asociado de Puerto Rico, the island's first constitution drafted and ratified by its own people. The text had been approved by referendum in March 1952 and by the U.S. Congress, which struck part of its bill of rights before ratification. The Commonwealth gave Puerto Rico internal self-government while leaving it an unincorporated U.S. territory whose residents are U.S. citizens but cannot vote for president and have no voting representation in Congress. Whether this status should give way to statehood or independence has been debated ever since, and Puerto Rico remains a Commonwealth to the present day. Puerto Rico's history begins with the Taíno of Borikén, whose island Christopher Columbus reached in 1493 and Juan Ponce de León colonised for Spain from 1508. For nearly four centuries it was a fortified Spanish possession, its harbour guarded by El Morro and La Fortaleza, its plantation economy built on sugar, coffee, tobacco, and enslaved African labour until abolition in 1873. After the failed Grito de Lares revolt of 1868 and a brief Charter of Autonomy in 1897, Spain ceded the island to the United States in 1898; Puerto Ricans received U.S. citizenship in 1917. In 1952 the island adopted its own constitution and became the Commonwealth (Estado Libre Asociado), a status whose future — statehood, independence, or the present arrangement — remains the central, unresolved question of Puerto Rican political life into 2026.
