The Temporal Accords, also known as the Temporal Accord, were a treaty that kept galactic powers possessing time travel technology from using it to alter history. In 2381, an early version of these accords existed between the powers of the Alpha Quadrant. Powers enforcing the treaty were known as the Accordists. (DTI novel: Watching the Clock)

Some powers violated the accords anyway and were opposed by those supporting the accords, leading to the Temporal Cold War. (ENT episode: "Shockwave")


The treaty was proposed by the Galactic Union, which evolved from the Alpha Quadrant Alliance in several branches. In the year 2769, the treaty was originally signed without incident on New Khitomer. The Na'kuhl protested against the Temporal Accords because it prohibited the restoration of their homeworld, itself lost due to a temporal attack by the Tholian Assembly in 2410.

The rogue temporal scientist Noye interrupted the historic event and attacked with a fleet led by the KIV Annorax. Na'kuhl ships intervened as well. The subsequent hostage situation and battle at New Khitomer, defused by members of the AQA and Starfleet, interrupted the proceedings. (STO - Future Proof mission: "Time and Tide")

The Temporal Accords outlined past incursions. Anthropologists traveled legally from 2769 to ancient Earth to observe Humans in Giza by following the stipulations of the accord. (ENT episode: "Cold Front")

The Temporal Defense Initiative grew out of the Accords. (STO video game: Agents of Yesterday)


According to Captain Benjamin Walker, a dozen species were present at the signing of the Temporal Accords. The Federation was represented by multiple factions. (STO - Future Proof mission: "Time and Tide")
