The Trabe are a space-faring civilisation from the Delta Quadrant. The Trabe had conquered the Kazon and integrated them in to their society as slave labour, forcing them to live in squalor seperated from the Trabe who lived in luxury. The Trabe went so far as to provoke the various Kazon sects in to fighting amongst themselves in order to keep them under control.
In 2346 Jal Sankur united the Kazon sects in rebellion against their Trabe oppressors, forcing them to flee their homeworld. The various sects to control of much of the Trabe space fleet, using it for their own ends, and soon began fighting amongst themselves once again, but they remained united in preventing the Trabe from finding a new homeworld.
In 2372, attempts by USS Voyager Captain Kathryn Janeway to form an alliance with one or more Kazon sects led to her forming such an alliance with the Trabe instead. The Trabe leader, Mabus, proposed a bolder plan, one that would bring peace between Voyager, the Trabe and the Kazon. However, after most of the Kazon sect leaders attended a peace conference, Mabus used this in an attempt to assassinate all of them in one move, decapitating the Kazon sects and leaving the Trabe unopposed in finding a new homeworld. This plan failed when Voyager fired upon the Trabe ship attacking the conference, forcing it to withdraw.
