The war lasted four years from 2358 to 2362. The conflict was started by the Tzenkethi to halt "Federation imperialistic expansion" towards their territory. The war was mainly along along the Federation-Tzenkethi border and in unclaimed space. The Tzenkethi did not attempt a widespread invasion of Federation territory nor did they attack any of the Federation's core worlds. (The Dominion War Sourcebook: The Fires of Armageddon)
