The Alliance was a combination of the Romulan Star Empire, Ferengi Alliance, Breen, Gorn and more who opposed the Federation in the 28th century. They believed the Federation had become corrupt due to organizations like Section 31, but in the rise in power they had become corrupt themselves. (Star Trek: 001: "New Beginnings")

The DominionEdit

In 2752, the Alliance had been discovered taking secret trips through the wormhole to the Gamma Quadrant in order to have talks with the Dominion about joining forces. ("The Last Place You Look")


In the same year, after having proven deceitful toward talks with the Dominion and invading Betazed, the Federation declared war with the Alliance. ("Red Sand, Dark Tide")


Wraiths played a role as figureheads in the Alliance. Although they barely showed interest and almost never told the Alliance what to do, they were the ultimate power. ("Restoration")
