Hunald I, also spelled Hunold, Hunoald, Hunuald or Chunoald, was the Duke of Aquitaine from 735 until 745. Although nominally he was an officer of the Merovingian kings of Francia, in practice Aquitaine was completely autonomous when he inherited it. His rule corresponds to the lowest point of the Merovingian monarchy, when the kingdom was in fact ruled by the mayors of the palace. Hunald was forced at the outset of his reign to accept the authority of the mayor of the palace Charles Martel, but he tried three times to throw it off in open revolt. He was unsuccessful, although he did manage to retain Aquitaine undiminished. In 745, he retired to a monastery, giving power to his son Waiofar. He later went to Rome, where he died during an attack on the city.
