United Colonies
The United Colonies was a union for "mutual safety and welfare" formed in 1643 by representatives of the colonies of Massachusetts Bay, Plymouth, Connecticut, and New Haven. The chief purpose of the league was coordination of defense and the settlement of boundary disputes; the internal affairs of each colony were to be left to its own management. With the revocation of the Massachusetts charter in 1684, the confederation was dissolved. This union was also known as the “New England Confederation.”
