- Not to be confused with the Cardassian Rebellion, the insurrection against Dominion rule led by Damar at the end of the Dominion War.
The Cardassian dissident movement was a resistance movement formed to resist and oppose the Cardassian Central Command and restore the authority of the Detapa Council. They believed this change was critical for the future of their people. (DS9: "Profit and Loss")
Professor Natima Lang, Hogue and Rekelen were members of this movement in the late 2360s and 2370s. In 2370, the three were pursued as fugitives from Cardassian forces and fled to Deep Space 9. Despite the agreement of the Bajoran Provisional Government to trade them for Bajoran prisoners, Quark facilitated their escape. (DS9: "Profit and Loss")
Legate Tekeny Ghemor was a secret supporter and leader of this movement. He was exposed in 2371 by the Obsidian Order and fled Cardassia. He left to live among the Mathenites, whose government had offered him sanctuary. (DS9: "Second Skin")
In 2372, following the destruction of the Obsidian Order, the movement successfully overthrew Central Command, thus restoring the civilian rule of the Detapa Council. The Klingons believed that the successful revolution was a result of Changeling infiltration within the Cardassian Union, which resulted in the unprovoked Klingon invasion of Cardassia. Ultimately the government was destroyed when Gul Dukat negotiated Cardassia's membership into the Dominion in 2373, with himself as the sole leader of Cardassia.
