The Europa Nova colonists (known as the Europani) have a strong dislike for the Cardassians, following an unspecified incident where the Cardassians turned the former seventh planet of the system into an asteroid belt. Standing orders for the Europa Nova military were to shoot any Cardassian vessel on sight. During the Dominion War, Europa Nova successfully repelled a Breen attack.

At the outbreak of the Gateways crisis, radioactive antimatter industrial waste from a Malon freighter in the Delta Quadrant threatened to irradiate the entire population. A joint task force including the USS Defiant, several Starfleet vessels, Bajoran Militia craft, and the Cardassian vessel CDS Trager were called in to evacuate the planet before the radiation reached lethal levels. The colonists were temporarily housed on Bajor and Deep Space 9. (DS9 - Gateways novel: Demons of Air and Darkness, TNG - What Lay Beyond short story: "The Other Side")
