Breen Confederacy

The Breen Confederacy was the official government of the Breen. This confederacy was located in the Alpha Quadrant. In late 2375, the Breen Confederacy entered the Dominion War by signing Dominion-Breen Alliance with the Dominion.

In addition to Breen itself, Portas V was part of the Breen Confederacy. By the 2370s, the Confederacy maintained diplomatic or trade relations with the Ferengi and the Cardassians.
