The Cardassian people are a ruthless race of humanoids in a military dictatorship, which rules their empire with a fist of iron. They have been involved in a bitter, extended conflict with the United Federation of Planets. An uneasy truce between the two adversaries was finally reached in 2366. Then in 2367, a historic peace treaty established a fragile armistice between the Federation and the Cardassian Union. Among other things, the treaty provided that captives of either government would be allowed to see a representative from a neutral planet following their incarceration.

The Cardassians were allied with the Dominion during the Dominion war. Their hatred of the Federation is known throughout the galaxy
Notes: The Galor class is the largest part of the Cardassian military, but it isn’t the strongest ship in the galaxy. A lone Galor class is easily out classed by most other Alpha Quadrant ships. To make up for this shortcoming Galors can often be found in large wolf packs. It is believed that until the Cardassian Union joined the Dominion, the Galor class was the most technologically advance ship Cardassia could build. Now the Galor class serves in a supporting role to more powerful Dominion ships.
Notes: The Keldon class is an enlarged and more powerful version of the Galor class. It can be identified by the new upper decks and different tail section.
Notes: Hideki class ship are designed to patrol the Cardassian boarder and raid neighboring solar systems for resources. The Hideki class has also been known to support larger Cardassian warships and Dominion fleets.
