Genocide
{{aquote|I would order them to go out and kill Bajoran scum. And they'd do it – they murdered them! And they came back covered in blood. But they felt clean. Now why did they feel that way, Major?

A genocide' was the deliberate and systematic destruction of an ethnic, racial, religious, or national group, perpetrated for ideological, religious, or political reasons.

Methods of genocide might include: 

Murdering members of the targeted group outright;
Forcing the group to live under conditions that will eventually lead to their death through starvation, exhaustion, illness, or injury;
Imposing measures intended to prevent births within the group, for example, forced .

One of the best known examples of genocide occurred during the Cardassian Occupation of Bajor. The occupation began a conquest for natural resources. The Cardassians treated the Bajorans as slave labor and interned much of the population in labor camps. However, over the course of forty years, the Cardassians' disdain for the Bajorans led to them deliberately imposing such conditions in these camps that the Bajorans interned in them quickly died. By the Occupation's end, millions of Bajorans had died in these camps, although the exact count is uncertain. ()

In the mid 24th century the Enarans committed genocide on a population group called the Regressives. The general Enaran population despised the Regressives for living an alternative partially technology free lifestyle. They systematically herded them into camps at first, restricting their rights and movements. Then later they forcibly began "relocating" them to a "colony" where they would be able to live as they chose freely. The relocation was a farce meant to soothe the Regressives into a false sense of safety and also to hide the real purpose of the effort to the Enaran population. The truth was that the ships which supposedly took the Regressives to their new colony did not actually go anywhere, it would simply vaporize the Regressives in the cargo hold. Dissidents and those that refused to be relocated were swiftly executed to silence them. Later the Enarans hid all evidence of the genocide, even blaming the Regressives themselves for their death by saying that they all died from a plague caused by their poor hygiene.
