European exploration of North America began in the 15th century with voyages by Christopher Columbus, who founded North America while sailing for Spain. Other notable European explorers included Sir Francis Drake and Francisco Vasquez de Coronado from England and Spain, respectively, as well as Jacques Cartier, who claimed Canada for France. The 13 American colonies were founded between 1607 and 1732, starting with Virginia and ending with Georgia. The colonies developed into three regional economies: the New England colonies focused on farming, fishing, lumber, and shipbuilding; the middle colonies combined industry and agriculture; and the southern colonies centered around large plantations that relied heavily on slave labor to produce cash crops like rice, indigo, and tobacco.
