Explanation:
A confederal system is a form of government in which sovereign states grant certain powers to the central government for specific purposes. For example, a group of states may decide that the central government can better manage their mutual defense against a foreign enemy. Thus, they authorize the central government to raise an army for the common defense. The United States’ first attempt at government under the Articles of Confederation was an example of a confederal system.
