Federation Alliance

The Federation Alliance was the accord between the United Federation of Planets, the Klingon Empire, and the Romulan Star Empire to combat the Dominion and its allies during the Dominion War.

The Gorn Hegemony also joined the Federation Alliance in late 2374, but only to provide materiel and repairs to any allied ship which required it. (TNG comic: The Gorn Crisis and novel: Articles of the Federation).

The first military engagement between Federation Alliance and Dominion forces occured at the First Battle of Chin'toka in 2374. This first engagement was a great success for the Alliance and became a major turning point in the war. During the Battle of Cardassia, the Cardassian Union switched sides and aided the Federation Alliance in overcoming the Cardassian's former allies. (DS9 episode: "Tears of the Prophets" and novelization: What You Leave Behind).
