The Forsworn certainly are not Nords, nor are they Bretons either. While they are ethnically related to the Bretons, having very similar physical features as noted by 'The Madmen of the Reach', their culture and beliefs are radically different from any other ethnic group in Skyrim or even the Empire as a whole (except maybe the Kothringi, if they still exist).
While it is alluded that they worship 'the Old Gods,' it is not explicitly stated who or what they worship. Judging from their blood-stained altars, penchant for human sacrifice, and gruesome trophies, it wouldn't be a stretch to believe they worship Molag Bal or Mephala. This is further supported by the existence of the shrine to Molag Bal hidden within the abandoned house in Markarth.
As for their history, the Forsworn were the 'native sons' of the Reach long before the Nords conquered and settled the area. It was Tiber Septim who first took Markarth by the sword, and that was when Nordic colonization and conversion began in earnest. It was during the Great War and the weakening of the Empire that the oppressed natives rose up and retook the Reach for themselves, expelling and murdering any Nords they came across. Ulfric Stormcloak and his merry men then formed a militia and drove them out, only to be arrested en-masse by the Thalmor for their heretical worship of Talos.
