After Christopher Columbus arrived in 1493, the island was colonized in 1508, and the capital city of San Juan founded in 1521. As a result of the Spanish-American War, Puerto Rico was relinquished to the USA by Spain in 1898. Today it is a self governing (very independent-minded) territory of the USA, and enjoys much autonomy. The narrow coastal plain rises into green (low) hills and mountains central and south. A few small rivers and lakes dot the landscape. The climate is usually hot and humid, with some lower temperatures found in the higher elevations. The island is a mecca for Caribbean cruise ships and tourists from around the world. Old San Juan is the most popular destination. Compared to other islands in the Caribbean, Puerto Rico has a high standard of living with a vibrant industrialized economy.
