Europa Nova was a human colony settled sometime in the late 2200s. The population decided not to join the United Federation of Planets, and remained non-aligned. 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.
