Terran Rebellion

In the mirror universe, the Terran Rebellion was formed by escaped Terran slaves to fight the Alliance.

Inspired by Kira Nerys and Julian Bashir's stories of "our universe", Benjamin Sisko was the first leader of the Rebellion. Unfortunately, he was killed in 2371, when the Alliance destroyed his freighter. Miles "Smiley" O'Brien took his place after "our" Benjamin Sisko returned to his universe, having helped the Rebellion keep Terok Nor, using the mirror universe version of the Defiant. (DS9: "Through the Looking Glass", "Shattered Mirror")

The Rebellion scored an impressive victory over the Alliance in 2375, with the capture of Regent Worf. Their fight continues. (DS9: "The Emperor's New Cloak")
