The United Colonies of New England, commonly known as the New England Confederation, was a short-lived military alliance of the English colonies of Massachusetts, Plymouth, Connecticut, and New Haven. Established in 1643, its primary purpose was to unite the Puritan colonies against the Native Americans. It was established as a direct result of a war that started between the Mohegan and Narragansetts. Its charter provided for the return of fugitive criminals and indentured servants, and served as a forum for resolving inter-colonial disputes. In practice, none of the goals were accomplished.
