Klingon-Cardassian Alliance
In the Mirror Universe, the Klingon-Cardassian Alliance was the historic union of the Klingons and the Cardassians, two former enemies, in the face of aggression from the Terran Empire. Following a series of reforms by Spock, the leader of the Empire, the Alliance conquered the Empire, enslaved Terrans and Vulcans, and became the dominant power in the Alpha Quadrant throughout most of the 24th century.
A Regent led the Alliance, delegating authority to various Intendants who administered individual sectors of Alliance territory.
It is unclear whether the Alliance had a central location of government, on either Qo'noS, Cardassia or elsewhere.
Bajor became a sovereign planet in the Alliance by the late 24th century, after the Alliance liberated Bajor from the Terran Empire.
In the latter half of the 24th century, a Terran rebellion against the Alliance was created due to interference from individuals from the primary universe. (DS9: "Crossover")
