In 1492, Genoese explorer Christopher Columbus, under contract to the Spanish crown, reached some Caribbean islands, making the first contact with the native people. On April 2, 1513, Spanish conquistador Juan Ponce de León landed on what he called "La Florida"—the first recorded European coming on what would become the U.S. mainland. Spanish settlements in the area were followed by ones in the present-day southwestern United States that drew thousands through Mexico. French fur traders established outposts of New France around the Great Lakes; France eventually claimed much of the North American interior, down to the Gulf of Mexico. The first successful English settlements were the Colony of Virginia in Jamestown in 1607 and the Pilgrims' Plymouth Colony in 1620. The 1628 chartering of the Massachusetts Bay Colony resulted in a wave of relocation; by 1634, New England had been settled by some 10,000 Puritans. Between the late 1610s and the American Revolution, about 50,000 convicts were shipped to Britain's American colonies. Beginning in 1614, the Dutch settled along the lower Hudson River, including New Amsterdam on Manhattan Island.
