The Maquis were a fictional group in the Star Trek universe, who served as recurring adversaries in the television series Star Trek: Deep Space Nine and Star Trek: Voyager. The group was made up of humans and members of extraterrestrial races, such as Bajorans, that refused to give up the colony planets on which they lived after they were ceded to the Cardassians as part of the treaty that ended the war between the United Federation of Planets and the Cardassian Union, as well as others who joined out of sympathy to their cause, including a number of Starfleet officers who resigned their posts to join. The Maquis saw themselves as a resistance movement, but were viewed by the Federation and the Cardassians as terrorists, having committed numerous transgressions against the Cardassians and Starfleet, such as theft, sabotage, and attacks upon their ships, though they usually avoided attacking Federation ships directly, preferring to warn them to get out of the way.
