Dominion War

After conceptual meetings, the writers began to introduce allusions to the Dominion into episodes of Season Two. The intention was to gradually increase the audience's awareness that there was a large and pervasive polity at work behind apparently innocuous events in the Gamma Quadrant. The Dominion and its methods are revealed across three episodes of the season.[11]

"Rules of Acquisition" marks the first mention of the Dominion,[12] when the Ferengi character Quark hears whispers of a powerful union of civilizations in the Gamma Quadrant with which he may be able to trade. Dialogue that seems inconsequential within the framework of a light-hearted episode was planned to ultimately create major change in the dynamics of Star Trek: Deep Space Nine.[2]

As Alpha Quadrant races begin to colonize planets in the Gamma Quadrant and their presence becomes known, disturbing reports indicate that what the Dominion cannot attain through trade is forcibly seized. These reports are justified in "Sanctuary", when a large fleet of Skrreea ships appears in the Alpha Quadrant, in search of a new homeworld in light of the conquest of their original planet by Dominion forces.[13] The actions of the Dominion are contrasted with the reactions of the regular characters to the Skrreea refugees. Executive producer Michael Piller has suggested that the plot evoked real-world debate surrounding Proposition 187, a Californian law concerning the rights of illegal aliens.[14]

The finale of Season Two, "The Jem'Hadar", permitted writer Robert Hewitt Wolfe to surprise the audience and challenge their opinions concerning the safety of the Federation and Starfleet, when the USS Odyssey, a Galaxy-class starship similar to the USS Enterprise from Star Trek: The Next Generation, is outfought and destroyed.[2][15] The Dominion is revealed to be a ruthless empire, using "carrot and stick" methods to control others, with three distinct races performing crucial roles.[16] The Dominion's Jem'Hadar shock troops capture Commander Sisko, Quark, and an alien named Eris, who is later identified as a double agent and one of the Vorta, the Dominion's negotiators and administrators. The Jem'Hadar send a representative to Deep Space Nine with the message that no further intrusions into Dominion space will be tolerated and to hand Major Kira Nerys a list of colonies and ships already eliminated for trespassing. The Federation dispatches a rescue team that returns Sisko's group to the station, but, while retreating back to the Alpha Quadrant, a Jem'Hadar ship launches a kamikaze run against the Odyssey, resulting in the destruction of both ships.[17]

With the third season, Ronald D. Moore and others started to write regularly for Star Trek: Deep Space Nine following the completion of Star Trek: The Next Generation.[8] Robert Hewitt Wolfe joined Ira Steven Behr in scripting episodes developing the Dominion plotline, beginning with "The Search". Behr became full executive producer at the midpoint of the season, after the departure of Michael Piller.

In the two-part season opener, "The Search", Commander Sisko returns from Starfleet Headquarters on Earth with a Defiant-class prototype starship, the USS Defiant.[18] Executive producer Rick Berman had to be convinced that the introduction of the Defiant would not distract the audience from the main starship of the latest Star Trek production, Star Trek: Voyager. The decision was made on the basis that a ship was needed to provide an avenue for stories set off the Deep Space Nine space station and that such a vessel would need the potential to oppose the Jem'Hadar, who had already been portrayed obliterating large ships. Audience research had also suggested that young male viewers were hoping for more action-oriented episodes with greater jeopardy.[19]

Season Three's Dominion stories explore the connection between Odo and his people, and their conflicting attitudes toward "solid" sentient lifeforms. The Defiant enters the Gamma Quadrant on a peace mission to locate the Founders in "The Search", and it is discovered that the Founders are of the same race as Odo. Despite a burning desire to return to his home, he finds his people's philosophy – that which you can control cannot hurt you – abhorrent, and he asks to return to the Alpha Quadrant.[20] The Founders, led by a character identified only as the "Female Changeling", acquiesce to Odo's request in the hope that he will ultimately rejoin them.[18][21]

Another facet to the Dominion was evaluated more closely in Season Three – the Jem'Hadar. In "The Abandoned", a juvenile Jem'Hadar is found alone and matures under Odo's guidance. The crew of Deep Space Nine witnesses the Jem'Hadar's difficulty in adjusting to a society with rules different from those of his native culture. Avery Brooks, directing this episode, has emphasized the story as a metaphor for African-American adolescents in the 20th century and their struggles with addiction and violence, their integration into American society, and how their upbringing might contribute to these problems.[22] Brooks ensured that Odo continued to support the maturing Jem'Hadar despite the alien's regression to Dominion custom, as a commentary on how modern society should engage with young people.[23]

"Improbable Cause" initiates a two-part adventure concerning the search for the Founders' homeworld, which concludes in "The Die is Cast".[24] Following first contact with the Founders, the Obsidian Order – a covert Cardassian intelligence force – ally themselves with the Tal Shiar, their Romulan counterpart, and launch a secret, pre-emptive strike to destroy the Founders' homeworld, hoping that the Founders and the rest of the Dominion will collapse. The Dominion successfully lures the fleets of the Tal Shiar and the Obsidian Order into a trap, eliminating both organizations. The plot establishes an atmosphere of suspicion amongst the Alpha Quadrant powers, initiated by the shapeshifters' abilities to assume other identities, which forms the basis of plots for Season Four.[25]

The Season Three finale turned out to differ significantly from the production staff's conceptual vision. Paramount did not favor the idea of a season-end cliffhanger which would have revealed the presence of shapeshifters on Earth. To continue the theme of paranoia about shapeshifters and the Dominion, "The Adversary" was instead scripted to set up a hunt for a Founder aboard the Defiant, incorporating some narrative elements at first intended to commence Season Four, while offering a more self-contained plot and using existing sets to reduce production costs.[26]

Rick Berman, Robert Hewitt Wolfe, and Ira Steven Behr originally expected to open Season Four with a two-part episode, postponed from the end of Season Three, that ultimately became "Homefront" and "Paradise Lost". Paramount determined that the writers needed to come up with a much different opener to satisfy the audience but without giving specific instructions. The production staff decided to begin a plotline based around suspicions between the Federation and the Klingons, finally leading to conflict between the former allies, which was inspired by a line from the Season Three episode "The Die is Cast".[27] With the Klingons set to reappear, Berman suggested the return of a character from Star Trek: The Next Generation – the Klingon Worf – as a permanent officer aboard Deep Space Nine.[28] While both the new plot and character offered interesting possibilities, the producers felt that their vision for Star Trek: Deep Space Nine was put off-course for almost one year.[29]

Season Four begins with "The Way of the Warrior", which marks the arrival of Worf. This episode is one of a few in this season to explore themes of suspicion and paranoia and their effect upon societies and relationships, building up to "Homefront" and "Paradise Lost". After the events of "The Die is Cast", fear about the identities of the infiltrator changelings leads the Klingons to suspect Dominion involvement in the new Cardassian civilian government. Their refusal to break off an invasion, even after Dominion involvement has been disproved, results in a military confrontation and diplomatic breakdown, and the Klingons attempt to seize Deep Space Nine. This seems to further the Founders' goal of the destabilization of the Alpha Quadrant as a prelude to their own invasion.[30]

In "Hippocratic Oath", the characters of Dr. Bashir and Chief O'Brien debate curing a group of Jem'Hadar soldiers of an addiction in the hope that they will rebel against the Dominion. There is discussion about the identity of the true enemy, the limits of duty, and whether soldiers are responsible for the actions of their leaders.[31] "To the Death" further investigates the themes of soldier duty and loyalty, and it contrasts the opposing rules of discipline that regulate Starfleet officers and Jem'Hadar troops. In addition, this episode introduced the Vorta representative Weyoun, who would become the most prominent Vorta in the rest of the series.[32]

In "Homefront", the mistrust generated by the shapeshifters continues, with Captain Sisko suspecting his own father and recommending a state of emergency be declared on Earth.[33] In "Paradise Lost", some Starfleet officers go further and attempt to implement a coup d'état against the President of the Federation after it is revealed that shapeshifters have infiltrated Earth and committed a terrorist attack. This leads to an armed conflict between Starfleet vessels for the first time in a century, according to the Star Trek in-universe timeline.[34] Sisko is able to force Admiral Leyton to abandon his efforts to impose martial law by telling him: "You're fighting the wrong war!"[35] Behr's favorite line from the episode is "Paradise never seemed so well-armed", highlighting one of many occasions when Deep Space Nine would point out the practical issues revolving around maintaining the peaceful culture of the Federation and the moral or immoral choices made to achieve this ideal.[36]

In the fifth season, the Dominion invasion of the Alpha Quadrant gathers pace, appearing in episodes such as "Apocalypse Rising", "In Purgatory's Shadow", "By Inferno's Light", and "Blaze of Glory". Robert Hewitt Wolfe and Ira Steven Behr were again responsible for the major Season Five episodes concerning the Dominion.[37][38][39][40]

In the Season Five opener, "Apocalypse Rising", Odo discovers that his race is capable of deceiving their own kind, as well as "solids", when he is led to believe that Klingon Chancellor Gowron is a Changeling instead of the General, Martok. This plot was planned to shift the focus of Star Trek: Deep Space Nine episodes back toward the struggle with the Dominion, which had been postponed in earlier production discussions with Paramount in favor of bringing Worf and a Klingon-based plotline into the series.[41][42]

In "In Purgatory's Shadow", it is discovered that Dr. Bashir has been kidnapped, imprisoned for weeks, and, in the interim, replaced by a Changeling. The shapeshifter double sabotages efforts to close the Wormhole and attempts to destroy the Bajoran sun, leaving the path open for Dominion fleets to enter the Alpha Quadrant.[37] In the following episode, "By Inferno's Light", the Cardassians become a member of the Dominion, and the Federation and Klingon Empire resolve to cast aside their mutual distrust and unite against the common threat. A garrison of Klingon troops is stationed on Deep Space Nine, under the command of the real General Martok, rescued from Dominion incarceration with Bashir.[38] In "Blaze of Glory", the characters confront the issue of ethnic cleansing when the Maquis – a resistance group of former Federation citizens now living in Cardassian space – are hunted down and ask for the assistance of Sisko, who used to criticize their methods.[39]

The Season Five finale, "Call to Arms", sets the scene for the commencement of full-scale war between the Dominion and the Federation during the final two seasons of Deep Space Nine. When the Dominion begins to send ships through the Wormhole, the Alpha Quadrant allies build a minefield at its mouth to cut off the supply line. The plot considers whether it is better for the planet Bajor to stand with their Federation friends or remain neutral in the coming war to protect themselves. Sisko persuades them that neutrality is the favorable course.[40]

Season Six, charting the turmoil of the Dominion War, faces themes of the moral dilemmas of conflict. New plot elements permitted Star Trek: Deep Space Nine to examine themes in a manner unlike preceding Star Trek productions, as characters are forced to re-evaluate their beliefs. The production staff resolved to start the season with a six-episode arc, the first attempted in the history of the Star Trek franchise.

Rick Berman originally pictured that the Dominion War would last for a limited number of episodes before a prompt resolution.[43] Planning the arc, Ira Steven Behr, Ronald D. Moore, and the writers conceived a longer chain of first five, then six connected episodes, stretching from "A Time to Stand" to "Sacrifice of Angels", as themes increased demands for greater narrative development.[44][45] No writer had previously contributed to a series involving arcs of such length, and Moore, Behr, and novice scripting partner & supervising producer Hans Beimler have all stated that the writing process changed as a result, with more production collaboration and interaction than for earlier seasons of Deep Space Nine.[46][47][48] The potential for serialization that Rick Berman had perceived from the start of Deep Space Nine came to fruition as a result of the multiple plotlines accumulating to form the Dominion War.[44]

The return of Gul Dukat as commander of the Dominion-controlled Deep Space Nine enabled the writers to contrast the space station of the audience's imagination to its incarnation as a former Cardassian mining facility. Former resistance fighter Major Kira is portrayed re-considering her ethical code as she sets out on the path to collaboration in "Rocks and Shoals", but the suicide of a Bajoran monk reminds her of the reality of her situation. Through "Rocks and Shoals", Deep Space Nine also revisits themes of war conduct as Sisko considers the morality of ambushing soldiers whom superiors have forsaken, only for events to force his hand.[49] In "A Time to Stand" and "Behind the Lines", the character of Odo is torn between the trust placed in him by Kira and the Bajorans, and his status as a Founder, when he joins Deep Space Nine's Dominion council and then neglects to help his comrades at a critical moment.

Fortune is reversed again in Season Six as Starfleet re-captures Deep Space Nine in the closing episodes of the opening arc, "Favor the Bold" and "Sacrifice of Angels". The USS Defiant stands alone in an attempt to hold back thousands of Dominion ships entering through the Wormhole. An intervention from the Wormhole Prophets, considered gods by the Bajorans, leads characters to ponder questions of faith and destiny.[50] Writer Hans Beimler wished to include mythological allusions, stating, "It's tragic hero stuff. A hero [Sisko] takes on things for others, but doesn't necessarily find any peace himself in the result."[51] Ira Steven Behr compares Sisko to the Biblical figure Moses, who fails to reach the Promised Land, and to the character of Ethan Edwards from the Western film The Searchers (1956), who neglects to return to his family once his task is complete.[51] It was determined that this facet to Sisko's character justified the use of divine intervention to resolve the Dominion threat:[52] the fleet disappears and the Federation regains control of Deep Space Nine. The defeat costs Dukat his mental health, the life of his daughter, Tora Ziyal, and his status as Cardassian leader. Dukat is the first, but not the only, character in Season Six to face the pain of loss in conflict. Later, in the season six finale "Tears of the Prophets", Worf loses his wife Jadzia Dax when she is killed by Dukat.

Although themes of death are apparent in Deep Space Nine's previous seasons, "Far Beyond the Stars" details how Sisko copes with the loss of a friend on a deeper psychological level. Experiencing visions of himself confronting racial discrimination against Black Americans in the 1950s, Sisko interprets useful parallels connected to his life on Deep Space Nine.[53] Sisko's response to the death toll of the Dominion War is re-examined in "In the Pale Moonlight".[54]

Additionally, Season Six introduces Section 31, a secret organization dedicated to preserving the Federation's principles regardless of the cost and legitimacy of its methods. In "Inquisition", the character of Dr. Bashir refuses to join Section 31 and reports its actions, but still ponders its significance: "But what would that say about us? That we're no different than our enemies? That when push comes to shove, we're willing to throw away our principles in order to survive?" Sisko replies, "I wish I had an answer for you."[55][56]

"In the Pale Moonlight" considers a similar moral dilemma when the Dominion captures an important Federation planet, Betazed, in a surprise attack. The subjugation of a planet familiar to the audience was used to heighten the sense of danger and the stakes for the characters.[57] In this episode, Sisko fuels a conspiracy intended to improve the war situation that ultimately results in the character of Elim Garak committing murder. In the context of the Dominion War, it is resolved to conceal the truth for the greater good.[54][58] Writer Michael Taylor has suggested, "It showed how Deep Space Nine could really stretch the Star Trek formula. It pushes the boundaries in a realistic way, because the decisions Sisko makes are the kinds of decisions that have to be made in war. They're for the greater good."[59]

Season Seven charts further dilemmas of conflict. Following the example of Season Six, the writers considered using an arc to conclude the multiple Dominion War threads in satisfying fashion, deciding that Star Trek: Deep Space Nine could not be concluded in one or two episodes alone.[60][61] A ten-episode arc was outlined to end Season Seven, the Dominion War, and all of Deep Space Nine, and more alterations were made as scripting progressed.[62]

Characters face issues of genocide: in "Treachery, Faith, and the Great River", Constable Odo learns of the engineered virus that Section 31 has disseminated among the Founders,[63] and in "When It Rains..." that Section 31 has infected him to communicate the disease.[64] While Dr. Bashir supports providing the Founders with a cure, others are unconvinced.

In “Penumbra”, it is revealed that the Dominion is receiving logistical support from the Son'a, who begin production of the Ketracel-white needed for the Jem'Hadar. Another opponent reveals itself when the Breen Confederacy signs a pact with the Dominion in "'Til Death Do Us Part". For "The Changing Face of Evil", writers Ira Steven Behr and Hans Beimler scripted a second strike against the Federation through a Breen assault on Earth. Later, with the addition of their new Breen allies, the Dominion retake the Chin'toka system, which sees the destruction of a number of Klingon, Romulan and Federation ships including the USS Defiant. Ronald D. Moore has stated: "We wanted to kill the Defiant as a statement on how tough the Breen were. We thought that would rock the characters and the audience." Behr explains that, "... the ship had become a character that had caught on in people's hearts and minds ... when the Defiant went down, that hurt."[65][66]

The resurgence in the conflict provided opportunities to introduce problems such as post-conflict psychological trauma in "The Siege of AR-558"[67] and injury when the character of Nog undergoes leg amputation in "It's Only a Paper Moon".[68] Moore has said that the plot of this episode was agreed on after an "extended argument" between Behr and Deep Space Nine creator Rick Berman and that such discussions were a common occurrence when war casualties were considered.[8] Michele and Duncan Barrett perceive the allusions made to the traumas of World War I.[69]

The concept of resistance is re-opened in the context of Cardassia rather than Bajor. Legate Damar becomes more and more frustrated with the deadlocked conflict and his situation as a Dominion puppet.[70] As Cardassian military losses mount and Dominion control of Cardassia deepens, he becomes alcoholic and criticizes the Dominion's power. Damar was originally to be revealed as a double agent for the Federation, but Moore then suggested the slave revolt of Spartacus as a model.[71] Damar establishes an underground resistance movement, is branded a rebel, and goes into hiding. Kira, Garak, and Odo are sent as "technical advisors" to help him in "When It Rains...".[64]

The relationship between Cardassians and Bajorans, former enemies turned allies, is charted in "Tacking Into the Wind", in which Damar and Kira's group abandon prejudice and collaborate to seize a Breen weapon.[72] Continuing into "The Dogs of War", Damar is forced to choose between his Cardassian comrades, stubborn in their beliefs, and the support of Kira and others whom he used to consider enemies.[73][74] As the tide turns against the Dominion, cut off from the Gamma Quadrant and without technological advantage, a last stand is prepared.[74] The Female Changeling orders the destruction of a metropolis, Lakarian City, to coerce the Cardassians back into line, but, instead, the Cardassian fleet defects, passing the advantage to the Alpha Quadrant alliance.[75] Consequently, an attempted extermination results in the deaths of 800 million Cardassians in a Dominion bombardment.[75]

Allusions to genocide contrast with ethical discussion concerning the engineered "Founders disease" and a potential cure. In "Extreme Measures", the characters of Dr. Bashir and Chief O'Brien locate a treatment inside the mind of Section 31 agent Luther Sloan. A moral debate ensues on what constitutes genocide. While Bashir supports offering a cure to the Founders, Sisko determines that the disease should be left to continue crippling the powerful opposition. However, in "The Dogs of War", Odo declares that this amounts to genocide of his species and is handed a treatment by Bashir.[76] In return for the Dominion's peaceful surrender, and the arrest of the Female Changeling on charges of war crimes, the Alpha Quadrant alliance permits Odo to heal the rest of his people.[77]

The Treaty of Bajor is signed aboard Deep Space Nine in the Season Seven finale, "What You Leave Behind, Part II". The conclusion to the Dominion War arc formed the resolution to Deep Space Nine as a series, and a moment for the production staff to settle the destinies of the main characters. Berman and Behr agreed with Paramount that the final episode of the series should concentrate on human drama rather than the endgame of the Dominion War.[78] Moore opines the production staff succeeded in ensuring the Dominion War acted as a means of deepening characterization.[79] Although further plots would have been scripted had Deep Space Nine continued into an eighth season, Behr accepted the resolution of the Dominion War at the end of Season Seven.[10]

In a 2007 interview with iF magazine, George Takei, who played Hikaru Sulu in Star Trek: The Original Series and its films, described Star Trek: Deep Space Nine as representing the "polar opposite" of Gene Roddenberry's vision and philosophy of the future.[80] Writer D. C. Fontana has stated in an interview that Roddenberry would have admired the later series for its dark themes, referring to Roddenberry's military service record in World War II.[81]

Roddenberry doubted that a series concentrating on themes aside from space exploration could endure, and voiced displeasure with initial concepts for Deep Space Nine presented to him in 1991. Rick Berman has explained that Roddenberry, although terminally ill, had given him his blessing for its development, but that he had no opportunity to discuss any of the ideas with Roddenberry.[59]

John J. O'Connor, writing for The New York Times in January 1993, noted that pre-release advertisements for Star Trek: Deep Space Nine offered "a new Star Trek era" and added, "Welcome to the Dark Side. The determinedly optimistic Mr. Roddenberry was partial to plots that made uplifting moral points. The new creators and executive producers, Rick Berman and Michael Piller, are shooting, so to speak, for something more ambivalent, less perfect."[82] In September 1996, before the start of Season Four, O'Connor was not sure the series was tackling contemporary themes adequately. He wrote, "Inevitably, though, there is an element of exhaustion seeping through the concept. With the Cold War over, perhaps the Roddenberry optimism seems merely naive as headlines bring news of murderous divisions between Serbs and Muslims, Kurds and Turks, Israelis and Palestinians, Irish Catholics and Protestants, and so on across an increasingly depressing globe. Star Trek offered a vision that leapt 300 years into the future. For too many people today, three years would seem a stretch."[83]

Cynthia Littleton, writing for Variety in 1998, summarized the ratings the series was receiving at the end of its sixth season: "Deep Space Nine may not go out on as high a Nielsen note as Next Generation, which wrapped a hugely successful run in 1994, but DS9 is hardly floundering. The series, which bowed in January 1993, consistently ranks among the top three first-run syndication hours in household and demographic ratings."[84]

In a 1999 edition of the Australian science-fiction magazine Frontier, Anthony Leong suggested that Deep Space Nine had not initially been envisaged to include a war story arc from the beginning. He demonstrated a preference for how the plot of Babylon 5 had been devised, while acknowledging how the Deep Space Nine writers had developed a continuing plotline: "... it is rare for a series creator to envision how the series will develop over time. Furthermore, the creative process in dramatic television writing tends to be organic, as events in the series will unfold based on the events that preceded it. For example, were the wars with the Klingons and the Dominion on Deep Space Nine foreseen by its creators back in the first season? Of course not ... these events developed over time through the input of its writing staff."[85]

In 2008, Nader Elhefnawy, contributor to The Internet Review of Science Fiction, asserted that, while less appreciated than other science-fiction series of the 1990s, Deep Space Nine had developed an interesting cast of characters, "thanks to the Dominion War, much of the richest and most exciting drama in the Star Trek franchise's history."[86]

Owen Williams, writing for Empire magazine, opines that Star Trek as a whole has been slow to adapt and develop to new trends, while singling out Deep Space Nine for special mention: "... arguably even the ace DS9 only got good in response to Babylon 5 ..."[87] Adam Smith, chief features writer for Empire commented in a 2009 article that, "It's hard to choose the best episodes of DS9 without mentioning the stories involving the Dominion War." He reported "The Search", "In the Pale Moonlight" and "Far Beyond the Stars" as the features staff's favorite episodes for their portrayal of darker themes and creating a change in direction.[88]

Star Trek: Deep Space Nine was nominated at the Academy of Science Fiction, Fantasy & Horror Films for a Saturn Award, from 1997 to 2000, in Best Genre Cable or Syndicated Series. It was nominated in technical and artistic categories at the Emmys in each season. Cinescape columnist Andrew Hershberger remarked in 2003 on the lack of critical success for science-fiction television: "Nobody cool would dare vote for a sci-fi show [for Outstanding Drama Series] that didn't have [Stanley] Kubrick or Chris Carter's name attached to it ... If Deep Space Nine was involved, you'd hear some real complaining on this end."[89]

In 2016, a reviewer at The Washington Post applauded the Dominion War saga for being the "richest narrative in the entire [Star Trek] universe."[90]

Academics have noted how the Dominion War plotlines have explored the human psyche as much as outer space. Lincoln Geraghty praises the ending to the story arc and Star Trek: Deep Space Nine as a series, and believes this is indicative of how the series manipulates the Star Trek ethos, identifying a theme of ambiguity as part of its continuing narrative.[91] Karin Blair, writing in 1997 at the time of Season Five, felt that the series was reflecting trends for American culture to re-consider its place in the global community.[92] Michele and Duncan Barrett comment on the "declining faith in rationalism that haunts Deep Space Nine" in their book Star Trek: The Human Frontier.[93]

In contrast, Robert Jewett and John Shelton Lawrence, authors of The Myth of the American Superhero, argue that the Dominion War plotlines in Deep Space Nine continue Star Trek's portrayal of "humanistic militarism", in that conflict is justified for the sake of humanity.[94] Criticism is levelled at Paramount's tie-in merchandising, in particular the slogan for the computer game Deep Space Nine: Dominion Wars, which is considered to emphasize the combat element at the expense of other themes.[95]

While television commentators and fans have noted associations with the Yugoslav Wars in the 1990s, some academics have noted parallels between the portrayal of the Dominion War and other historical conflicts. Michele and Duncan Barrett identify a number of themes relating to World War I in Star Trek, especially "in the bleak and costly alliances and endless casualty sheets that characterize the protracted Dominion War in DS9."[69]

Star Trek: The Dominion War crossover miniseries explores events leading up to the Dominion War.[96] Two novels focus on the crew USS Enterprise. A Call to Arms (1998) and Sacrifice of Angels (1998) are based on seven interlinked episodes from Deep Space Nine's fifth and sixth seasons, beginning with "Call to Arms". The Battle for Betazed (2002), by Charlotte Douglas and Susan Kearney, and Tales of the Dominion War (2004), a short story collection edited by Keith DeCandido, tie in to the series.

Star Trek: Deep Space Nine – Millennium miniseries explores an alternate-timeline accidentally created by the crew of the USS Defiant (NX-74205). The series was partially adapted as The Fallen (2000). An omnibus edition was published in 2002.

Star Trek: Deep Space Nine – Mission Gamma miniseries follows the exploits of the USS Defiant (NX-74205), under the command of Elias Vaughn. These Haunted Seas (2008) collected Twilight and This Gray Spirit.

Worlds of Star Trek: Deep Space Nine explores the worlds featured in the Deep Space Nine television series. Characters featured during the Dominion War arc, are peppered throughout the novellas, especially in the third volume. The concept for the series was developed by Marco Palmieri.[97]^: 269

Star Trek: Deep Space Nine – Gamma miniseries follows the crew of USS Robinson (NCC-71842), under the command of Benjamin Sisko. Only one novel has been published. Not to be confused with the Mission Gamma (2002) miniseries which has a similar premise.

Star Trek: Deep Space Nine – The Fallen (2000) is a third-person shooter video game loosely based on the Millennium trilogy of novels by Judith and Garfield Reeves-Stevens. Characters introduced during the Dominion War story arc appear in the game.

Star Trek: Deep Space Nine – Dominion Wars (2001) is a real-time strategy video game set during the later seasons of Deep Space Nine.[98] The player is tasked with defending Federation assets against attacking Dominion forces.
