(May 19, 1643), was the first document in America where colonies united themselves. The colonists of New Plymouth, New Haven, Massachusetts & Connecticut, covenanted together, stated:
The Articles of Confederation between the plantations under the government of Massachusetts, the plantations under the government of New Plymouth, the plantations under the government of Connecticut, and the government of New Haven with the plantations in combination therewith:
Whereas we all came to these parts of America with the same end and aim, namely, to advance the Kingdome of our Lord Jesus Christ, and to injoy the liberties of the Gospell thereof with purities and peace, and for preserving and propagating the truth and liberties of the gospell. …
And whereas in our setting (by a wise providence of God) we are further dispersed upon the sea coasts and rivers than was at first intended. …
The said United Colonies for themselves and their posterities to jointly and severaly hereby enter into a firm and perpetual league of friendship and amity for offence and defence, mutual advice and succor upon all just occasions both for preserving and propagating the Gospel and for their own mutual safety and welfare.335
