A confederation is a group of sovereign states, each of which is free to act independently from the others. In 1776, when America gained its independence, a loose confederation was formed among the thirteen colonies. Under this confederation, the states were united by a weak national government, which was completely lacking constitutional authority. The national government had some control over issues such as military affairs and foreign policy. The states, however, took the majority of power into their own hands, such as the power to coin money and raise armies.
