Vortimer (in Welsh Gwerthefyr) is the eldest of the three elder sons of Vortigern named in the Historia Brittonum and in some later works. According to these, Vortimer was made king in place of his father Vortigern to fight against the Saxons. Vortimer fought and defeated the Saxons in four battles, but died soon after. Vortimer had ordered that he be buried in a sea-port, but this order was not followed.
