The Klingon-Cardassian Alliance was the dominant power of the Alpha Quadrant, it merges the Klingon Empire and the Cardassian Union into a one supreme army of the Duyi'zu Universe after the first war and became the major player of the Second War. The Alliance was the union of two former axis forces, the Klingons and the Cardassians, in the face of aggression from the growing Alliance of Civilzations. The Alliance itself was led by a Regent, who delegated authority to various Intendants who administrated the individual sectors of Alliance territory. The Alliance was ruled by Gorkon and Gul Dukat. They joined the Imperialist Alliance and later the Nationalist Alliance.
