As early as 1643 Massachusetts, Plymouth, Connecticut and New Haven formed a "perpetual confederation" under the name of the "United Colonies of New England." The motive for this union was mainly offence and defence against the Indian tribes and the Dutch, though provision was also made for the extradition of servants and fugitives from justice. The management of the common interests of these colonies was vested in a board of eight commissioners--two from each colony--and, in transacting the business of the confederacy, the consent of six of the eight commissioners was required. Any matter which could not be thus disposed of was to be referred to the four colonial legislatures. The general government thus provided for could not inter-meddle "with the government of any of the jurisdictions." No provision was made for amending the "Articles of Confederation," and only by the unanimous consent of these colonies could any other colony be admitted to the confederacy. This union lasted for over forty years.[13] Again in 1754 the pressure of impending war with the French and Indians brought together at Albany a convention of delegates from seven colonies north of the Potomac. A plan of union drafted by Benjamin Franklin was recommended by this convention, but it was not regarded with favor either by the colonies or by the English government. The former regarded it as going too far in the direction of subordinating the separate colonies to a central colonial authority, while for the latter it was too democratic.[14] The union of all the colonies under the Articles of Confederation was finally brought about through the pressure of military necessity during the Revolution. Nor is it surprising, in view of the history of the American colonies, that they reluctantly yielded up any powers to a central authority. We must bear in mind that the Revolution was in a measure a democratic movement, and that democracy was then found only in local government. The general governments of all countries were at that time monarchical or aristocratic. Tyranny in the eighteenth century was associated in the minds of the people with an undue extension or abuse of the powers exercised by the undemocratic central government. It is not surprising, then, that the Revolutionary federal constitution, the Articles of Confederation, should have failed to provide a general government sufficiently strong to satisfy the needs of the country after the return of peace.
