In 1584 was established the first english colony called Virginia and the first permanent settlement was founded in 1607 and was called Jamestown. In 1620 a group of puritan refugees from England known as the Pilgrim fathers reached the coast of North America on their ship Mayflower and founded a settlement Plymouth there. The first colony in the north was called New England. The settlers in New England were hard working, courageous and therefore the colonies were prosperous. During the Great English Revolution the Royalists emigrated to Virginia, where they established large tobacco-plantations. After 1660 the colonies in the South began to replace white labour with black slaves from Africa. The colonies in the north and south were separated by a Dutch colony in the mouth of the river Hudson called the Netherlands with the chief town New Amsterdam on Manhattan Island.
