Only one year after Spain granted Puerto Rico self-rule, American troops raise the U.S. flag over the Caribbean nation, formalizing U.S. authority over the island’s one million inhabitants.
In July 1898, near the end of the Spanish-American War, U.S. forces launched an invasion of Puerto Rico, the 108-mile-long, 40-mile-wide island that was one of Spain’s two principal possessions in the Caribbean. With little resistance and only seven American deaths, U.S. troops were able to secure the island by mid August. After the signing of an armistice with Spain, the island was turned over to the U.S forces on October 18. U.S. General John R. Brooke became military governor. In December, the Treaty of Paris was signed, ending the Spanish-American War and officially approving the cession of Puerto Rico to the United States.
