A long conflict between the United Federation of Planets and the Cardassian Union


The Federation-Cardassian Wars, known in the Federation as the Cardassian Wars, was a prolonged conflict between the Federation and the Cardassian Union, which started at least as far back as 2347 and lasted into the 2350s. Smaller scale hostilities, seemingly not officially considered part of the war, continued into the 2360s. By the mid-2360s, the wars had settled into an effective stalemate, with neither side gaining advantage in terms of firepower or territory. In 2367 a truce was established, which enforced an end to active hostilities but left many of the major questions of the conflict unresolved. The final treaty to end all hostilities of the wars was not signed until 2370. This formed the Demilitarized Zone between the two powers, effectively creating a new border and clarifying the ownership of such planets as Dorvan V.

Losses during the wars left deep scars on both sides. For instance, Gul Evek lost two of his three sons during the Cardassian Wars, and Starfleet Captain Benjamin Maxwell lost his entire family. Famous Federation ambassadors Spock and Sarek disagreed publicly over the Cardassian Wars, which left a bruise on their relationship and their family.

However, this new treaty was not received by everyone with acceptance. The Maquis organization was formed from Federation-born colonists to fight the Cardassian occupation of their homes in the Demilitarized Zone after their colonies were ceded to the Cardassian Union.
