"Ardashir I or Ardeshir I (Middle Persian: 𐭠𐭥𐭲𐭧𐭱𐭲𐭥, Modern Persian: اردشیر بابکان, Ardašire Bâbakân), also known as Ardashir the Unifier (180 – 242 AD), was the founder of the Sasanian Empire. He was also Ardashir V of the Kings of Persis, until he founded the new empire. After defeating the last Parthian shahanshah Artabanus IV on the Hormozdgan plain in 224, he overthrew the Parthian dynasty and established the Sasanian dynasty. Afterwards, Ardashir called himself "shahanshah" and began conquering the land that he called Iran.
There are various historical reports about Ardashir's lineage and ancestry. According to Al-Tabari's History of the Prophets and Kings, Ardashir was son of Papak, son of Sasan. Another narrative that exists in Kar-Namag i Ardashir i Pabagan and Ferdowsi's Shahnameh also states it says that Ardashir was born from the marriage of Sasan, a descendant of Darius III, with the daughter of Papak, a local governor in Pars." - (en.wikipedia.org 11.08.2021)
