Qo'noS was ruled by the tyrant Molor until the 9th century when Kahless the Unforgettable slew him in single combat using the newly forged Sword of Kahless. Kahless ruled as emperor of a united Klingon Empire and conquered the Fek'Ihri. After his death, Qo'noS was invaded and sacked by the Hur'q. One of the artifacts stolen was the Sword of Kahless.
Qo'noS was first visited by humans in 2151, by Jonathan Archer. By the 23rd century Qo'noS had a large Orion embassy sector and aliens including Trills frequenting it. In 2293 Praxis was destroyed due to overmining which threatened the habitability of the planet. The damage to Qo'noS meant the Klingons could no longer afford to maintain a hostile attitude towards the Federation. Their resulting detente lead to the Khitomer Accords and the Federation-Klingon alliance.

A battle ensues after the meeting between the Khitomer Alliance and Klingon Defense Force against House Mo'Kai and other Klingon Rebels, leading to a Civil War.
- “A Day Long Remembered”: The final battle of Qo'noS takes place and the player, Martok, J'Ula and L'Rell fight ground troops making their way to the Great Hall. Aakar wounds Martok at the courtyard, forcing him to retreat and lures J'Ula into a duel to the death with J'mpok while he fights the player and L'Rell. With the help of Adet'pa, the player breaks through his personal shields and transporters, killing him just as J'Ula falls to J'mpok. However, J'Ula passes the Chancellorship to L'Rell instead, and a celebration event is held two weeks following the fall of J'mpok in the Great Hall.
- “Remain Klingon”: While battle occurs on the surface, a team of Alliance forces coordinated by Adet'pa, Kagran and Martok (after beaming up) work to destroy the Targ and the Kri'stak. L'Rell, having received Chancellorship, ceases hostilities and announces the end of J'mpok's reign, calling all warriors to return to the Empire without vengeance befalling them.
