Ardashir's father, Papak, was originally the ruler of a region called Khir. However, by 200, Papak had managed to overthrow Gochihr and appoint himself the new ruler of the Bazrangids. Papak's mother, Rodhagh, was the daughter of the provincial governor of Pars. Papak and his eldest son Shapur managed to expand their power over all of Pars. Subsequent events are unclear due to the elusive nature of the sources. It is certain, however, that following the death of Papak, Ardashir, the governor of Darabgerd, became involved in a power struggle with his elder brother Shapur. Sources reveal that Shapur, leaving for a meeting with his brother, was killed when the roof of a building collapsed on him. By 208, over the protests of his other brothers, who were put to death, Ardashir declared himself ruler of Pars.
