The colonial history of the United States covers the period of European colonization of North America from the early 16th century until the unifying of the Thirteen British Colonies and creation of the United States in 1776, during the Revolutionary War. In the late 16th century, England, France, Spain, and the Dutch Republic launched major colonization expeditions in North America. The death rate was very high among early settlers, and some disappeared in early attempts altogether, such as the ones in the English Lost Colony of Roanoke. Nevertheless, successful European colonies were established within several decades.
European settlers in the Thirteen Colonies came from a variety of social and religious groups, including adventurers, farmers, indentured servants, tradesmen, and a very few from the aristocracy. Settlers included the Dutch of New Netherland, the Swedes and Finns of New Sweden, the English Quakers of the Province of Pennsylvania, the English Puritans of New England, the Virginian Cavaliers, the English Catholics and Protestant Nonconformists of the Province of Maryland, the "worthy poor" of the Province of Georgia, the Germans who settled the mid-Atlantic colonies, and the Ulster Scots of the Appalachian Mountains. These groups all became part of the United States when it gained its independence in 1776. Parts of what had been New France were incorporated during the American Revolution and soon after. Parts of New Spain were incorporated in several stages, and Russian America was also incorporated into the United States at a later time. The diverse colonists from these various regions built colonies of distinctive social, religious, political, and economic style.
