Klingon-Cardassian Alliance

In the mirror universe, the  (more commonly known as simply the Alliance) is a faction made up of an alliance of Klingons and Cardassians dating back to at least the 24th Century.

History

 * The Alliance formed in response to the threat of the Terran Empire during the latter faction's height.
 * Sometime after 2267, an Imperial Starfleet officer named became Emperor of the Terran Empire. He instituted a series of reforms that made the Empire more tolerant to non-Terrans. Unfortunately for them, these reforms also left the Empire vulnerable to an invasion by the Alliance. By the mid-24th century the Empire had been conquered and the Alliance controlled much of the Alpha Quadrant. Terrans and Vulcans became slaves to the Alliance, and the Bajorans had successfully petitioned for membership.
 * In 2370, Julian Bashir and Kira Nerys cross over to the mirror universe Terok Nor via the wormhole. They inspire the Terran slaves to fight against the Alliance. The following year the Rebellion begins, led by Miles O'Brien's counterpart.
 * The Alliance loses Terok Nor to the rebels in 2372, who manage to build a Prime Universe Defiant class starship using stolen schematics.
 * In 2374 Kira's counterpart attempts to steal the Orb of Prophecy and Change to unite the Bajoran's against the Alliance.
 * Regent Worf of the Alliance surrenders to the in 2375.
 * By 2409, the Alliance has been conquered by the newly reformed Terran Empire. Surviving forces are reduced to focusing more on avoiding Imperial detection and attempting to establish new colonies outside of Terran-controlled space ( & ).
