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")
