Colonial expansion increased in the late 16th century as people left England for religious and economic reasons, establishing new colonies in the West Indies, America, India, and South Africa. By the early 18th century, 13 colonies had formed along the east coast of America, divided into New England, southern, and middle colonies. The first colony of Virginia was founded by Sir Walter Raleigh and became a center for tobacco plantation and the slave trade. Puritan colonists established religious communities including Plymouth and colonies in New England. Catholic colonists founded Maryland for religious tolerance. Quaker colonists established Pennsylvania under William Penn. New York originated as a Dutch colony that was renamed after coming under English control.
