Bro Gwened

It was peopled by Christianized Britons fleeing the Saxon invasions of Britain, who displaced or assimilated the remaining pagan Veneti Gauls.

Both Gwened[4] and Vannes[1] reflect separate developments of the Latin Veneti, the Romans' name for the Gaulish tribe in the area.

[7] In the early 6th century, Macliau served as one of the earliest bishops of Vannes prior to usurping his nephew's inheritance in neighboring Cornouaille.

In the mid-7th century, Bro Gwened was united with Domnonia under its king Saint Judicaël, who was descended from a daughter of Budic II.

Domnonia's rulers thenceforth reigned as the high kings of Brittany, with Bro Gwened forming part of their lands.
