The Typhon Pact was an alliance of six interstellar states formed in the wake of the Borg Invasion of 2381 as an opposing force to the United Federation of Planets and its allies. The pact consisted of the Romulan Star Empire, Tzenkethi Coalition, Breen Confederacy, Gorn Hegemony, Tholian Assembly and the Holy Order of the Kinshaya, all of which had hostile relations with the Federation and/or Klingon Empire in their previous history and all of which had typically previously maintained xenophobic and isolationist policies.
