The Articles of Confederation of the United Colonies of New England, 1643

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 which 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. The confederation was weakened in 1654 after Massachusetts refused to join the war against the Netherlands during the First Anglo-Dutch War. However the confederation regained importance during King Philip's War in 1676.
