In the
Star Trek universe, Deep Space Nine was originally a
Cardassian mining and refinery station named
Terok Nor in orbit around
Bajor, and it was built by Bajoran slave labor under Cardassian rule in 2346. The station was commanded by
Gul Dukat, the last Cardassian prefect of Bajor. It was abandoned toward the end of the
Cardassian occupation of Bajor in 2369; the Cardassians stripped items of value on their way out. The station had some major problems, including a trap left by the Bajoran resistance that nearly killed everyone on the station when it was accidentally activated by the new tenants. In 2369, the Bajorans assumed control of the station. The Bajoran provisional government requested the assistance of the
United Federation of Planets, who renamed it Deep Space Nine (DS9) and placed Commander
Benjamin Sisko in command. Despite the Federation's presence, the station remains subject to Bajoran law. Shortly after Sisko assumed command, his crew discovered the
Bajoran wormhole. The station was moved to the mouth of the wormhole to secure Bajor's claim to it, after which the station assumed great commercial, scientific and strategic importance. These upgrades were first used against the Klingons in their offensive against
Cardassia in early 2372. At the beginning of the
Dominion War in late 2373, the station was temporarily lost to the Dominion. In early 2374, Federation and Klingon forces retook it after the
Battle of Bajor. Aside from
a failed Bajoran military coup, the Dominion's occupation, and a brief leave of absence from late 2374 to early 2375, Sisko, promoted to captain in 2371, remained in command of
Deep Space Nine. In late 2375, at the end of the
Dominion War, Colonel
Kira Nerys assumed command. Colonel Kira is still in command when the station is next seen on screen in 2381.
Relaunch novels In the continuing story novels, DS9 was forced to jettison its power core due to the actions of
Dominion rebels. As one of his first actions as chief of operations of the station,
Nog had
Empok Nor towed to the station's location, and used its power core as a replacement. The remainder of Empok Nor was broken down for scrap and spare parts. Later, DS9 would host
Bajor's formal acceptance into the Federation. With the station now under Federation law,
Quark almost closed down his bar, but remained open after
Rom arranged to have it designated as the
Ferengi embassy to Bajor, placing it under the jurisdiction of
Ferenginar. In the year 2383, DS9—while under the command of Captain
Ro Laren—was destroyed by a series of bombs planted by the Typhon Pact, when an attempt to distract Starfleet from their efforts to discreetly use the wormhole backfires, although the station is evacuated in time so that only a thousand people are lost of those on the station at the time, none of whom are major characters. In honor of the station, and the
Bajoran people,
Starfleet Command and the
Federation Council agreed to build a new station in the Bajoran system and name it Deep Space Nine. ==Crew and inhabitants==
