Terran Empire

In the mirror universe, the Terran Empire was a militaristic Human-dominated governmental authority controlling Earth and surrounding space through the use of the powerful Imperial Starfleet. It was one of the dominant powers in the Alpha Quadrant during the 22nd and most of the 23rd centuries, until being overthrown and conquered by the Klingon-Cardassian Alliance in 2295. In several alternate timelines, the Terran Empire continued to exist as a dominant power well into the 24th century. In at least one of these, it had conquered the Klingon Empire by the 2360s.
