This democratic tendency is seen also in our first federal constitution, the Articles of Confederation, which was framed under the impulse of the Revolutionary movement. This document is interesting as an expression of the political philosophy of the Revolution; but like the state constitutions of that period, it has had few friendly critics among later political writers. Much emphasis has been put upon its defects, which were many, while but little attention has been given to the political theory which it imperfectly embodied. That it failed to provide a satisfactory general government may be admitted; but this result must not be accepted as conclusive proof that the principles underlying it were altogether false. The chief feature of the Articles of Confederation was the entire absence of checks and balances. All the powers conferred upon the general government were vested in a single legislative body called the Continental Congress, which was unchecked by a distinct executive or judiciary. In this respect it bore a striking resemblance to the English government of to-day with its omnipotent House of Commons. But, unlike the English government of to-day, its powers were few and narrowly limited. Its failure was due, perhaps, not to the fact that the powers granted to the confederation were vested exclusively in a single legislative body, but to the fact that the powers thus granted were not sufficient for maintaining a strong and effective central government. The reason for the weakness of the general government under the Articles of Confederation is obvious to the student of American history. It was only gradually, and as necessity compelled cooperation between the colonies, that the sentiment in favor of political union developed. And though some tendencies in this direction are seen more than a century before the American Revolution, the progress toward a permanent union was slow and only the pressure of political necessity finally brought it about.
