Ever since détente with the Klingon Empire, and the Tomed Incident forced the Romulans to engage in only minor skirmishes with the Federation, the Alpha Quadrant had remained relatively peaceful for decades, interrupted only by the Borg incursion at Wolf 359 in late 2366. The Dominion War changed all of that, bringing the horrors of war to the doorstep of Earth and other homeworlds of Federation members for the first time in generations.

History can sometimes remember complex events in broad strokes, but the Dominion War was filled with complicated causes and effects, events and intrigues. The Dominion War Timeline gives a detailed look at the conflict, from its origins to its major battles to its conclusion.
