Between the 15th and the 18th century the major European powers, England, French, Dutch, and the Spanish competed for the land and resources of the New World.
Great Britain built colonies along the Atlantic coast but the French blocked the British in the north, Canada and around the Great Lakes. Spain built colonies in the south like Florida. In 1763 the French and British fought a war called the French and Indian Wars. The French lost and had to give Great Britain all the land, so Great Britain now controlled all the land from the Atlantic to the Mississippi River.
Great Britain developed the thirteen colonies and divided them into 3 groups:
New England Colonies
The north and central colonies had strong economies, industry and trade. The southern colonies had big farms, tobacco and rice which required lots of help. So slaves were brought from Africa.
In 1763 the British government made the Royal Proclamation. This did not allow Colonists to move west of the Appalachian mountains. The Colonists got angry and slowly decided to be free. On July 4, 1776 the American colonies declared their independence from England. With help from the French and Spanish the colonists defeated the British and became free. In 1783 the Treaty of Paris was signed and America became a country. America gave Florida to Spain because Spain helped America during the war.
