The Taurus Pact
Provided with executive powers by their respective governments, Thot Gor, Tholian delegate Azrene and Prefect Zogozin of the Gorn Hegemony formed the mutually beneficial Taurus Pact at the former site of Starbase Vanguard in the Taurus Reach.
Conflict with the Pact was a looming menace for the Klingons and the Cardassians, both of which tried to broker a truce in order not to face a two- or three-front war. When the Cardassian Union descended into madness-induced chaos, the Klingons worried the Breen and the Tholians might attempt to seize Cardassia.
Following the victory of the Terran Rebellion and the dissolution of the Alliance in 2380, the Terran Protectorate, the forerunner of the Galactic Commonwealth, was recognized by the Taurus Pact as a nascent state. In addition, nonaggression treaties were signed with the Klingon Empire and Cardassia. (ST - Mirror Universe novel: Rise Like Lions)
