The colonial population passed 1 million by 1760

The Thirteen Colonies, also known as the Thirteen British Colonies[2] or the Thirteen American Colonies,[3] were a group of colonies of Great Britain on the Atlantic coast of North America founded in the 17th and 18th centuries which declared independence in 1776 and formed the United States of America. The Thirteen Colonies had very similar political, constitutional, and legal systems, and were dominated by Protestant English-speakers. The New England colonies (Massachusetts, Connecticut, Rhode Island and New Hampshire), as well as the colonies of Maryland and Pennsylvania, were founded primarily for religious beliefs, while the other colonies were founded for business and economic expansion. All thirteen were part of Britain's possessions in the New World, which also included colonies in Canada, Florida, and the Caribbean.
