The Treaty of Bajor ended the Dominion War and was signed on Deep Space 9 in 2375 by personnel of the Federation Alliance and the Dominion-Breen Alliance. One of the stipulations of the treaty was that the Female Changeling surrender herself to the United Federation of Planets and stand trial for war crimes.
Upon the signing of the treaty, Admiral William Ross remarked, "Four hundred years ago, a victorious general spoke the following words at the end of another costly war. Today the guns are silent. A great tragedy has ended. We have known the bitterness of defeat and the exultation of triumph. From both we have learned there can be no going back. We must go forward to preserve in peace what we've won in war." (DS9: "What You Leave Behind")
