PUERTO RICANSThe inhabitants of the US Caribbean dependency of Puerto Rico. Settled by the SPANISH in 1508, Puerto Rico remained a backwater until the 1830s, when immigrants from newly independent LATIN AMERICAN states established a plantation economy. This entailed importing a limited number of African slaves, whose impact on the largely European culture was likewise limited. By the end of the 19th century an increasingly brutal colonial regime was facing growing resistance, and in 1897 Puerto Ricans won a degree of autonomy, which was terminated with US occupation in 1898. Thereafter their relationship with the USA was unusual. Puerto Ricans resented attempts to Americanize them, but accepted the advantages of their position. In 1917, for example, they became US citizens of an AMERICAN commonwealth. This meant they had limited self- government, could not vote in federal elections and paid no federal taxes. Incomes remained low, and in many fields, not least welfare, their standards were lower than in the USA but higher than in most of Latin America.
