Maquis

The Maquis was a paramilitary group between 2370 and 2373. The Maquis consisted primarily of former citizens of the United Federation of Planets whose home worlds were ceded to the Cardassian Union by the Treaty of 2370. Having to live under Cardassian domain without Federation support, the Maquis (named after a similar anti-Nazi resistance group during Earth's World War II) used violent means to counter Cardassian oppression. (DS9 episode: "The Maquis, Part I")

The Maquis was obliterated following the alliance between the Cardassian Union and the Dominion. (DS9 episode: "By Inferno's Light")
