The Bajorans were a race conquered by the Terran Empire. They were liberated by the Klingon-Cardassian Alliance and became leading members. Some, however, joined the Terran Rebellion.
Contrary to their weak counterparts from the mirror universe Bajorans did not believe in any gods, not even ever having heard of any "Prophets" until a Terran and a duplicate of Kira Nerys, Intendant of Bajor, entered our universe through a previously unknown wormhole, said by the duplicate Kira to be the home of her people's "Prophets".
