He came to power in 317BC.[http://www.monarchie-noblesse.net/angleterre/bretons/bretons.htm Monarchie Nobelesse website, Bretons]

Following the return of Elidurus to the kingship of Britain, Ingenius joined with his brother Peredurus and attacked their older brother. They succeeded in capturing him and locked him in a guarded tower in Trinovantum. Instead of fighting over who ruled the island, they split the island, giving all land south and west of the River Humber to Ingenius and all land to the north and east, including Albany, to Peredurus. He ruled his portion of the island for seven years then died, giving the whole of the island to his brother, Peredurus.{{Cite journal |last=Birkhan |first=Helmut |date=2020 |title=The unholy Grail in Britain: A remarkable example of secondary paganisation |url=https://classiques-garnier.com/autour-du-graal-questions-d-approche-s-the-unholy-grail-in-britain.html |journal=Civilisation médiévale |volume=39}} His son Idvallo would later become king of Britain.
