Audrii I was the son of Shaddam I and brother of Ezhar I. However he didn't rule until after the end of the First Protectorate, because of unresolved differences between his father's heirs.
Protector Harmon II had Imperial aspirations and refused to step down from the throne, until Iason Atreides settled down the differences and persuaded Harmon to accept Audrii.
His first task was to restore Abulurd III Harkonnen's title which were removed by Harmon. However Abulurd's son, Iosif was caught in bed with Audrii's son and as a result House Harkonnen were demoted to their lesser title of Lords Tupelo, and were required to pay a large fine into the Imperial treasury.
