From Alathra Wiki

A confederation (also known as a confederacy or league) is a union of sovereign groups or states united for purposes of common action. Usually created by a treaty, confederations of states tend to be established for dealing with critical issues, such as defence, foreign relations, internal trade or currency, with the central government being required to provide support for all its members.

An example of this in Alathra is the Confederacy of Mirenirenic, which is a federal union of states, with each state having high amounts of autonomy whilst still functioning as a single entity for diplomatic affairs. Types of states with varying seperation.
