The Khitomer Accords consisted of two historic peace treaties between the Klingon Empire and the United Federation of Planets and were the first step in reconciliation between the two powers.

The First Khitomer Accords were signed at the Khitomer Conference in 2293 on the planet Khitomer.

First Khitomer Accords[]

The explosion of the Klingon moon Praxis in 2293 caused severe ecological disasters on the Klingon homeworld and an almost complete shutdown of the Klingon economy. Following these events, the Klingon chancellor Gorkon initiated peace talks with the Federation in which Captain Spock served as a special envoy to the Empire. The peace conference was first scheduled to be held on Earth, but was later relocated due to Chancellor Gorkon's assassination on his way to Earth. The new venue was Camp Khitomer, on the Klingon planet Khitomer, which was kept secret in order to prevent further assaults. Despite further actions by a Klingon/Federation/Romulan conspiracy, the Khitomer Conference was a success and a turning point in Klingon-Federation relations. (Star Trek VI: The Undiscovered Country)

Curzon Dax represented the Federation in the negotiations, at which the Romulan Senator Pardek was also present. (DS9: "You Are Cordially Invited"; TNG: "Unification I")

As part of the agreement, the Empire relinquished its historical claims to the Archanis sector, which was located in Federation territory on the Klingon border. (DS9: "Broken Link")

In 2344, the Battle of Narendra III had a decisive influence on interstellar history. As the Klingons were betrayed by the Romulan Star Empire and were deeply impressed by the courage of the USS Enterprise-C, this event had the effect of finally ending Romulan-Klingon relations and solidifying Federation-Klingon relations. (TNG: "Yesterday's Enterprise")

Khitomer Accords

Gowron re-signs the Khitomer Accords

In 2372, Gowron withdrew the Klingon Empire from the Khitomer Accords in response to the Federation Council's condemnation of his invasion of the Cardassian Union. (DS9: "The Way of the Warrior")

Upon deciding to have the Klingons leave the treaty, the writing staff of Star Trek: Deep Space Nine was careful not to disrupt the plot lines of chronologically simultaneous Star Trek productions. "By taking the Federation/Klingon truce and unraveling it, we were not going to affect the plot lines of the movies or of Voyager, since they are nowhere near an area of space to be affected", said Rick Berman. (Star Trek: Communicator issue 104, p. 9)

The following year, Gowron reinstated the treaty at Captain Benjamin Sisko's request when an alliance between the Dominion and the Cardassian Union threatened to throw the Alpha Quadrant into war. (DS9: "By Inferno's Light")

In 2380, Ensign Brad Boimler worried that failing to deliver General K'orin to negotiations on Tulgana IV would put him and Beckett Mariner in violation of the Khitomer Accords. (LD: "Envoys")

Second Khitomer Accords[]

The Second Khitomer Accords banned the use of subspace weapons. The Son'a openly flouted this accord in 2375. (Star Trek: Insurrection)

It was never established in the film whether the Son'a were parties to the Second Khitomer Accords and therefore bound by the ban.

In 3190, to dissuade Ruon Tarka's suggestion of using a special weapon that would use an isolytic burst to destroy the Dark Matter Anomaly, President Laira Rillak points out that such a weapon was banned by the Khitomer Accords. (DIS: "...But to Connect")


Background information[]

It is possible that the second accords may be the 'peace treaty' referred to by Richard Castillo in "Yesterday's Enterprise", suggesting a signing date in the 2340s. The second accord could be the formal alliance between the Federation and the empire referenced in The Next Generation. It is also possible that it occurred after the events of DS9: "By Inferno's Light" in which the Federation and the Klingon Empire renewed their alliance. This is supported by the fact that Chancellor Gowron and Admiral Ross said in DS9: "When It Rains..." they had met at Khitomer.


The Khitomer Accords were expanded to include the Imperial Romulan State and the Ferengi Alliance in the novel A Singular Destiny, set in 2381. The Cardassian Union and Talarians were also invited to join.

In the year 2399, the Khitomer Accords break down between the Federation and the Klingon Empire, and all out war is imminent, according to the storyline in Star Trek Online. Khitomer Vortex is the name of a Special Task Force mission in the game available only to flag officer-ranked players. In this mission, the player must join with 4 other players to prevent the Borg from utilizing a temporal vortex and thus corrupting the timeline.
