Terran Rebellion

In the mirror universe, the Terran Rebellion was an organization formed by escaped Terran slaves to fight the Alliance, in the aftermath of the earlier collapse of the Terran Empire.

The Rebellion was in place by 2333. The leaders of this early phase of the Rebellion were unclear, but Montgomery Scott and Phigus Simenon were both influential members. However, the earlier Rebellion was largely unsuccessful, as most of the Terran civilization remained enslaved and oppressed until the Rebellion took on greater significance in 2370, with Benjamin Sisko and a crew of Terran associates escaping from the Alliance and beginning major confrontations after an encouraging and disruptive visit from the counterpart universe Julian Bashir and Kira Nerys. Sisko was inspired by stories of the prosperous "real universe" from Kira and Bashir and began his rebellion against the Alliance on Terok Nor. Unfortunately, he was killed in 2371, when the Alliance destroyed the small fightercraft he was flying. Miles "Smiley" O'Brien took over as leader after the counterpart universe Benjamin Sisko helped the Rebellion keep Terok Nor, using a mirror universe copy of Sisko's ship, the Defiant. One of the many acts of internal sabotage of Alliance operations was to end their ability to use their cloaking devices by using new forms of sensors to disrupt the cloaking fields and the sensors detected the ships through the field. This crippled the Alliance's war machine to a massive degree.

The Rebellion scored an impressive victory over the Alliance in 2375, with the capture of Regent Worf.

The Rebellion experienced a massive boost in manpower when the entire Xenexian population (which numbered millions), under their new leader M'k'n'zy of Calhoun, joined the Rebellion against the Alliance. (NF - Obsidian Alliances short story: "Cutting Ties") Not long afterwards, 'Mac' and his ship, the Excalibur, rescued Selar, who had been undercover posing as a Romulan. She found evidence that the Romulans were building a thalaron radiation weapon for the Alliance. Mac, Selar, and Soleta arrived on Romulus in disguise as Romulan scientists, only to be discovered by Hiren. However, Alliance soldiers ambushed the four of them and discovered that the Alliance planned to destroy Romulus with the thalaron weapon. Unfortunately, although the four escaped death, the bomb went off, completely annihilating the Romulan homeworld. Despite this, Praetor Hiren decided to give command of the entire surviving Romulan fleet to Mac, so that they could join the Terran Rebellion's fight against the Alliance.

Another major breakthrough was when the Rebellion's scientists successfully copied the designs of the counterpart universe Defiant-class warships and Romulan cloaking devices. These combined improved the Rebels' space warfare capabilities and cost the Alliance many ships and facilities.

The fighting began to spread and slaves everywhere deserted their posts and joined the Rebellion at Terok Nor or one of the Rebels bases in the Badlands. One such case was Keiko Ishikawa, who became Smiley's girlfriend and XO. They later became the parents of Molly O'Brien.

Rebellion leaders Zek and Julian Bashir eventually stole vast amounts of resources and equipment from Alliance territory and planned to construct a fleet of cloaked Defiant-class warships and use them to destroy the Alliance homeworlds of Cardassia and Qo'noS. Unfortunately, these plans were undone when the Empok Nor shipyard—where the warships were being constructed—was destroyed and many rebel leaders were killed. O'Brien managed to rally his troops from the brink of dispair by promising a "Revolution" against the Alliance (when in fact he had no idea how to do this). When last seen, Keiko and O'Brien's relationship was getting more serious and the Rebels' victory against the Alliance seemed assured.

The final victory of the Rebellion eventually came, and Earth signed an armistice with the Alliance. The newly freed Earth elected not to restore the Terran Empire, however; rather, humanity became a member of a new organization, the Galactic Commonwealth.
