Star Trek: Deep Space Nineended in 1999 with “What You Leave Behind”, the series finale that concluded the third live-actionStar Trekshow. Shortly after then-Commander Benjamin Sisko (Avery Brooks) was assigned to help Bajor join the United Federation of Planets following the Cardassian Occupation, the discovery of the Bajoran Wormhole—and its Prophets—set up the simple premise that setDS9apart from its predecessors.Now open to the Gamma Quadrant, Deep Space Nine became the location of Starfleet’s strategic first defense against the Gamma Quadrant’s reigning power,the Dominion, and the epicenter ofStar Trek’s Dominion War.
Leading up toDS9’s final season,shifting loyalties and clashing philosophies among Alpha Quadrant powers set the stage forStar Trek: Deep Space Nine’s conclusion. As the Bajoran Emissary, Captain Sisko’s warning to remain neutral kept Bajor from being destroyed in a Dominion invasion. The Klingon Empire and Federation became allies after both wereinfiltrated by Changeling impostors. Gul Dukat (Marc Alaimo) sought to redeem himself in the eyes of the Cardassian government by allying Cardassia with the Dominion. Sisko’s darkest hour swayed the Romulans against the Dominion, earning another powerful ally for the Federation.
How Captain Sisko & Starfleet Won Star Trek: DS9’s Dominion War
Unexpected Collaboration Between Former Enemies Saved The Alpha Quadrant
Captain Benjamin Sisko and Starfleet secured victory for the Alpha Quadrant in a hard-fought, collaborative effort that concluded in the last episode ofStar Trek: Deep Space Nine’s nine-part finale.Starfleet, the Klingon Empire, and the Romulan Star Empire formed the Federation Alliance, with combined numbers that could finally overcome the Dominion’s forces. Sisko’s USS Defiant crew led the charge that pushed the surrounded Dominion back to Cardassia Prime. There,Colonel Kira Nerys(Nana Visitor) and Elim Garak (Andrew Robinson) helped Damar’s (Casey Biggs) Cardassian Rebellion sabotage the Dominion’s Alpha Quadrant stronghold.
The final victory came from Constable Odo offering the Changeling leader the cure to Section 31’s morphogenic virus.
Colonel Kira, Garak, and the Rebels eliminated Weyoun (Jeffrey Combs) and captured the female Changeling (Salome Jens). With the Dominion’s proverbial head cut off, the Jem’Hadar and Breen soldiers serving the Dominion retaliated and killed most of the Cardassian Rebels. The final victory came from Constable Odo (Rene Auberjonois) offering the Changeling leader the cure to Section 31’s morphogenic virus;in exchange for Odo bringing the cure to the Great Link, the female Founder finally surrendered.
Captain Sisko Became A Prophet Of Bajor
“The Sisko Is Of Bajor.”
While the Deep Space Nine crew celebrated the Federation Alliance’s victory over the Dominion,Captain Sisko was called to fulfill his role as Emissary of the Prophets and become a Prophet of Bajor.In the final spiritual battle ofStar Trek: Deep Space Nine,Sisko was the Prophets' representative, and Gul Dukat was chosen by the Bajoran pah-wraiths, after the pah-wraiths rejectedKai Winn Adami’s (Louise Fletcher)sacrificial murder of Dukat. Sisko and the Prophets defeated Winn and Dukat, setting Benjamin’s next chapter as a Prophet in motion.
Star Trek: Deep Space Nineseason 7, episode 1, “Image in the Sand” revealed that Captain Sisko’s mother, Sarah (Deborah Lacey), had been embodied by a Prophet to ensure Benjamin would bridge the gap between the wormhole aliens and the people of Bajor.
Instead of simply whisking Benjamin Sisko away forever, the non-linear Prophets understood that Ben needed to say goodbye to his loved ones.Sisko promised to someday return to his wife, Kasidy Yates-Sisko (Penny Johnson); their unborn son; and Ben’s adult son, Jake (Cirroc Lofton).This promise is the closest thing to a cliffhanger inStar Trek: Deep Space Nine’s otherwise satisfying finale.
What Happened To DS9’s Crew After The Series Ended
Life Went On For Most Of Deep Space Nine’s Crew
The end ofStar Trek: Deep Space Ninesignaled a new normal, even for those who stayed on Deep Space Nine after the Alliance’s victory.Deep Space Nine continued to be operated by a joint Starfleet and Bajoran militia crew, with Colonel Kira Nerys in command after Sisko’s ascension.Dr. Julian Bashir (Alexander Siddig) and Lieutenant Ezri Dax (Nicole de Boer) continued serving on the station at the beginning of their new relationship. Quark (Armin Shimerman) openedfranchises of Quark’s Bar and Grillacross the Quadrant, while remaining manager of the original Quark’s on DS9.
However,the end of an era meant a change of scenery for more ofStar Trek: Deep Space Nine’s characters than those who stayed behind. Constable Odo brought the cure forSection 31’s morphogenic virusto the Founders when he joined the Great Link. Chief Miles O’Brien (Colm Meaney) moved back to Earth with his family to teach at Starfleet Academy. Grand Nagus Rom (Max Grodénchik) changed Ferengi society as Zek (Wallace Shawn)’s successor, while Lieutenant Nog continued his Starfleet career. Elim Garak returned to Cardassia, now devoid of his enemies, to help rebuild his homeworld.
11 Deep Space Nine Characters Star Trek Still Needs To Bring Back
Star Trek: Deep Space Nine has had some characters return on Star Trek on Paramount+ shows, but some of DS9’s biggest names are still waiting.
As aStar Trek: The Next Generationcharacter,Lieutenant Commander Worf’s timelinemay be the most robust of anyDS9series regular.Worf (Michael Dorn) slayed Chancellor Gowron (Robert O’Reilly) and earned the right to lead the Klingon Empire, then passed the title to the better-suited General Martok (J.G. Hertzler). Instead, Worf became the Federation’s ambassador to the Klingon Empire, Captain of the USS Enterprise-E, and an eventual “subcontractor” for Starfleet Intelligence inStar Trek: Picard.
DS9 Didn’t Get A Movie But It Got A Documentary
What We Left Behind Gave Fans A Look At Making Star Trek: Deep Space Nine
Star Trek: Deep Space Ninedidn’t continue with movies after it ended, likeStar Trek: The Next Generationdid, butDS9’s executiveproducer and showrunner Ira Steven Behr released the documentaryWhat We Left Behind: Looking Back at Star Trek: Deep Space Ninein 2019.TheDS9documentary used archival production footage and new interviews fromStar Trek: Deep Space Nine’s cast and crewto detail the behind-the-scenes difficulties of makingDeep Space Nine,like Paramount’s pushback on serialization, skepticism aboutTNG’s Worf, and planned character arcs that never took off.
What We Left Behindexplained that an HD release ofStar Trek: Deep Space Ninewould be prohibitively expensive because all its CG scenes were originally rendered for standard definition, so they’d need to be recreated from scratch.
What We Left Behindshowed how a typicalDeep Space Ninestory was constructed by followingStar Trek: Deep Space Ninewriters René Echeverria, Ron Moore, Hans Beimler, and Robert Hewitt Wolfe, breaking the hypothetical first episode ofStar Trek: Deep Space Nineseason 8. In the proposed real-time follow-up toDS9’s ending, the surprise return of Captain Benjamin Sisko 20 years later prompts a reunion betweenDS9’s main characters.The story of where everyone is and how they get back to DS9 isn’t canon,but it’s interesting to see what the writers might have had in mind.

Star Trek: Lower Decks' own Lieutenant Beckett Mariner (Tawny Newsome) served on Deep Space Nine sometime during the Dominion War.
Star Trek: Lower Decksseason 5, episode 9, “Fissure Quest” finally showsBashir and Garak as a married couple, althoughthe holographic doctor modeled on Julian Bashir and the version of Elim Garak who joined Starfleet are multiversal variantsof the characters fromStar Trek: Deep Space Nine. The oft-discussed but never seen Curzon Dax also makes an appearance, voiced by Fred Tatasciore.
Why A DS9 Reunion Like TNG Got On Star Trek: Picard Can’t Happen
Some DS9 Actors Have Sadly Passed Away
Star Trek: Picardseason 3 reunitedStar Trek: The Next Generation’s primary cast, but a similar reunion to recapture the magic ofStar Trek: Deep Space Ninehasn’t been possible since the 2019 deaths of Rene Auberjonois and Aron Eisenberg. While many living members ofStar Trek: Deep Space Nine’s castwould be available for a reunion,Avery Brooks retired from acting and separated himself fromStar Trek: Deep Space Nine. But even if aDS9cast reunion is impossible, modernStar Trekshouldn’t keep overlookingDeep Space Nine.
Modern Star Trek Pretty Much Admits Deep Space Nine Is Still The Franchise’s Outcast 32 Years Later
Star Trek: Deep Space Nine is still popular 30 years after its premiere, but several factors make it difficult for DS9 to compete wi modern Star Trek.
Star Trek: Deep Space Nine’s bold risks ultimately improved theStar Trekfranchise.DS9didn’t shy away from critical examinations of religion, politics, and the limits of morality.The broad mix of Federation and alien cultures on the station removedTNG’s limiting “no interpersonal conflict” rule, soDS9could freely dive deep intoStar Trek’s broader themes of diversity and tolerance. Alien cultures weren’t monoliths or stereotypes, but real people to be understood despite their differences. Now more than ever,Star Trek: Deep Space Nineis necessaryStar Trek,and its ending celebrates the legacy of what it left behind.
