Was regarded by Caesar as the most powerful of the British tribal monarchs in 54BC. Nothing further is known about him. The next identifiable ruler of the Trinovantes was Addedomaros who started his rule from c.20-15BC, but whether he was the son or grandson of Mandubracius is not known; indeed, it is possible that Mandubracius was the last of his line, and that his throne was taken by, or given to the family of Addedomaros.
