  • The Federation-Cardassian Treaty, primarily negotiated by Admiral Alynna Nechayev, formally ends the Federation-Cardassian War, following the cessation of hostilities three years earlier with the Federation-Cardassian Armistice of 2367, and creates the Demilitarized Zone between Federation and Cardassian space.
  • A subspace rift develops in the Hekaras Corridor due to excessive warp speed travel. All Starfleet ships are ordered to not go beyond Warp 5 until a solution is found.
  • The Dominion conquers the T-Rogorans.
  • The Federation makes first contact with the Dominion when Jem'Hadar forces pass through the Bajoran wormhole, attacking several Alpha Quadrat outposts, taking several officers hostage and attempting to plant a spy within the Federation. While the incursion fails, it makes the start to the Dominion Cold War.


  • First contact between the Romulan Empire and the C'hakilian Empire.
  • Non-aggression signed between the C'hakilian Empire and the Krazzle Empire following a hundred years of minor border skirmishes between the two powers.
  • The USS Voyager is assumed to be lost with all hands while on a mission in the Badlands.
  • Late in the year, the Cardassian Obsidian Order and the Romulan Tal Shiar attempt a preemptive joint strike against the Dominion in the Battle of the Omarian Nebula. The battle is the first major engagement with the Dominion, and it ends disastrously for the Cardassian/Romulan task force.


  • Portal discovered by Starfleet linking the Alpha Quadrant to the Raeyan Sector.
  • Reports leak out of the Cardassian Union that its military government has been overthrown by a popular uprising and replaced by the civilian Detapa Council.
  • New technology is issued to starships, effectively cancelling the Warp 5 Speed Limit
  • The Dominion replaces Martok, an influential general in the Klingon Defense Force, with a changeling, who calls for a massive invasion of Cardassian space, starting the Klingon-Cardassian War in an attempt to further weaken resistance among Alpha and Beta Quadrant powers.
  • The Federation-Klingon War breaks out after the Klingons withdraw from the Khitomer Accords and following their increasingly aggressive stance against all major powers in the region.



  • Deep Space 9 is retaken by a Federation fleet including elements from the Fourth Fleet.
  • First contact between the Krazzle Empire and the Federation.
  • The Federation is devastated by the Battle of Betazed, when the Dominion launches a surprise assault that successfully captures the planet.
  • The non-aggression pact between the Romulan Star Empire and the Dominion is forfeit when the Romulan Star Navy declares war and strikes at fifteen bases along the Cardassian border.
  • Late in the year, the Federation, Klingons and Romulans ("Federation Alliance") launch their first major offensive against the Dominion with the First Battle of Chin'toka. While ultimately successful, the losses incurred prevent further advances into Cardassian space.



  • The Fourth Fleet assigns Task Force 38 to start charting the Delta Quadrant through the Union-F'hoca portal.
  • Worf, son of Mogh, names Martok as Chancellor of the Klingon Empire, and relations between the Klingons and the Federation take a turn for the better.
  • Diplomatic relations are established between the Federation and the Trigati Republic.



  • The USS Voyager returns to the Alpha Quadrant after destroying one of six Borg transwarp hubs, dealing a significant blow to the Borg Collective.
  • C'hakilian Empire captures Avalon Fleet Yards, the Raeyan System and a number of other Federation outposts in the Raeyan Sector, beginning the C'hakilian War. At the invitation of the Klingon Empire, Federation personnel bivouac to the Klach d'Kel Brakt system.
  • Task Force 21, the Fourth Fleet's intelligence wing, launches successful attacks behind C'hakilian lines to disrupt supply lines.
  • Near the end of the year, a massive Federation-Klingon fleet successfully retakes C'hakilian-held assets in the Raeyan Sector while simultaneously fending off a counterattack on Klach d'Kel Brakt.
