Puerto Rico

unincorporated organized territory of the US with local self-government; republican form of territorial government with separate executive, legislative, and judicial branches; note - reference Puerto Rican Federal Relations Act, 2 March 1917, as amended by Public Law 600, 3 July 1950

Populated for centuries by aboriginal peoples, Puerto Rico was claimed by the Spanish Crown in 1493 after Christopher COLUMBUS' second voyage to the Americas. In 1898, after 400 years of colonial rule that saw the indigenous population nearly exterminated and African slave labor introduced, Puerto Rico was ceded to the US as a result of the Spanish-American War. Puerto Ricans were granted US citizenship in 1917.
