Ardashir I, also known as Ardashir the Unifier, was the founder of the Persian 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 Arsacid dynasty and established the Sasanian dynasty. Afterwards, Ardashir called himself "shahanshah" and began conquering the land that he called Iran.
