From 2369 to mid-2370, the Federation sent exploration parties to the Gamma Quadrant. After the Dominion destroyed the U.S.S. Odyssey, they launched into a three-year period in which they destabilized the Alpha Quadrant's delicate political balance.

In late 2373, the Federation and the Dominion officially declared war on each other, after the Dominion attacked and captured Deep Space Nine.

The war went badly for the Federation, until the Klingon Empire and the Romulan Star Empire joined forces with them to fight the Dominion.

After curing the lead Founder of a deadly disease, the Dominion signed a peace treaty with the Federation in 2375, ending the war.


The Cardassian Union has been deposed as a major power in the Alpha Quadrant, and a large casualty rate was present on both sides.
