About this period many evidences were given of a general combination of the neighboring Indians against the settlements of New England; and apprehensions were also entertained of hostility from the Dutch of Manhadoes. A sense of impending danger suggested the policy of forming a confederacy of the sister-colonies for their mutual defence. And so confirmed had the habit of self-government become since the attention of England was absorbed in her domestic dissensions that it was not thought necessary to consult the parent state on this important measure. After mature deliberation articles of confederation were digested; and in May, 1643, they were conclusively adopted.

By them "The United Colonies of New England"—Massachusetts, Plymouth, Connecticut, and New Haven—entered into a firm and perpetual league, offensive and defensive.

Each colony retained a distinct and separate jurisdiction; no two colonies could join in one jurisdiction without the consent of the whole; and no other colony could be received into the confederacy without the like consent.

The charge of all wars was to be borne by the colonies respectively, in proportion to the male inhabitants of each between sixteen and sixty years of age.

On notice of an invasion given by three magistrates of any colony, the confederates were immediately to furnish their respective quotas. These were fixed at one hundred from Massachusetts, and forty-five from each of the other parties to the agreement. If a larger armament should be found necessary, commissioners were to meet and ascertain the number of men to be required.

Two commissioners from each government, being church members, were to meet annually on the first Monday in September. Six possessed the power of binding the whole. Any measure approved by a majority of less than six was to be referred to the general court of each colony, and the consent of all was necessary to its adoption.

They were to choose annually a president from their own body, and had power to frame laws or rules of a civil nature and of general concern. Of this description were rules which respected their conduct toward the Indians, and measures to be taken with fugitives from one colony to another.

No colony was permitted, without the general consent, to engage in war, but in sudden and inevitable cases.

If, on any extraordinary meeting of the commissioners, their whole number should not assemble, any four who should meet were empowered to determine on a war, and to call for the respective quotas of the several colonies, but not less than six could determine on the justice of the war or settle the expenses or levy the money for its support.

If any colony should be charged with breaking an article of the agreement, or with doing an injury to another colony, the complaint was to be submitted to the consideration and determination of the commissioners of such colonies as should be disinterested.
