End of the Dominion War and the Treaty of Bajor

By 2375 the Dominion, strengthened by its alliance with the Breen, still held Cardassia, but its Cardassian subjects were turning against it. A resistance movement led by Damar, with help from Kira Nerys and Elim Garak, sabotaged Dominion facilities across Cardassian space. In reprisal, the Founders ordered the destruction of entire Cardassian cities.

The Federation, Klingon and Romulan fleets launched a final offensive and pushed through to Cardassia Prime, helped when the Cardassian ships changed sides in mid-battle. As the Jem'Hadar began exterminating the Cardassian population, Odo reached the Female Changeling, linked with her and cured her of the morphogenic disease ravaging the Founders. She ordered all Dominion forces to stand down.

The war formally ended with the Treaty of Bajor, and the Founders' leader agreed to stand trial. The cost was immense: Cardassia lay in ruins and some 800 million Cardassians had been killed. Odo returned to the Great Link to share the cure with his people.
