The Maya civilization spread into the area of Belize between 1500 BC and AD 300 and flourished until about 1200. European contact began in 1492 when Christopher Columbus sailed along the Gulf of Honduras. European exploration was begun by English settlers in 1638. This period was also marked by Spain and Britain both laying claim to the land until Britain defeated the Spanish in the Battle of St. George's Caye (1798). It became a British colony in 1840, known as British Honduras, and a Crown colony in 1862. Independence was achieved from the United Kingdom on 21 September 1981.
