The Articles of Confederation were essential a "prequel" to what we now know as the Constitution. During America's fight for independence, there became a need for the colonies to unite. In 1776, the Continental Congress met, and formed a committee to prepare this document, which was drafted by Delegate John Dickinson. All thirteen colonies had to agree on The Articles of Confederation and, as a result, it was rectified several times until they could come to an agreement. It was finally approved in 1781.
Many of the states were worried about the government having too much power and, therefore, much of the power remained with the states. A unilateral government which consisted of a Congress was established, and each state had one vote. The national government had no power over judicial matters. Congress, however, was given power over foreign relations and could make international treaties and alliances, had control over the army and navy, could declare war, coin money, run the postal service, and manage Indian affairs.
