Shrouded in mystery the Breen are a warrior race, but have quite a distinct codex than e.g. the Klingons in that they prefer to take prisoners for slave labor. Morality as most sentient species know it, is mostly replaced by values like duty and survival. Therefore they commit actions, deemed atrocities by most races, but in a Breen mind, the goal always justifies the means. Thus on the other hand killing without purpose is not compatible with the Breen sense of personal honor.
- The Breen have been a long-standing enemy of the Klingon Empire.
- The Breen Confederacy entered the Dominion War in the 2375 supporting the Dominion.
- During the war the Breen succeeded in a surprise attack on Starfleet Command in San Francisco, Earth.
- The same year a joint Dominion/Breen fleet took back Chin'toka, destroying an allied fleet, among others the U.S.S. Defiant under Captain Sisko.
- In 2388 the Orion Syndicate starts negotiations with the confederacy. The Orions had depleted their home world's resources and were in need of assistance. In 2394, the Orions struck a deal with the Klingon Empire and became their allies.
