Definition of confederation

The word "confederation" originates from the medieval Latin term "confoederatio," which literally means "union by oath." It refers to an association of states, nations, or other political entities that come together for a common purpose or interest, typically through a written agreement or treaty. The first recorded use of the term in English dates back to the late 15th century, in reference to a group of Scottish nobles united in opposition to James III's rule. Today, the word is commonly used in political contexts to describe alliances, confederacies, and other forms of interstate cooperation.
