Puerto Rico grew sugar under Spanish rule, though on a smaller scale than Cuba. During the wars of Spanish American independence it remained loyal to Spain, and its leaders shared Cuban leaders’ fear that Haiti’s example would spread. Slavery was abolished in 1873. The island passed to the United States in 1898 and remains a commonwealth under its flag.

Puerto Rico (US territory) · Feminism and the Tunisian Revolution
Puerto Rico, a US territory, was the site of the first large-scale tests of the contraceptive pill in 1956. A 1965 government survey found that about a third of ever-married women aged 20 to 49 had been sterilized; the practice was common enough to be called la operación. In 1974 Puerto Rican activists, including Dr Helen Rodríguez-Trías, founded the Committee to End Sterilization Abuse in New York.
