William I of Gascony

From Wikipedia, the free encyclopedia

William I (French: Guillaume, Gascon: Guilhem, Spanish: Guillermo) was the Duke of Gascony, appointed in 846 following the death of Seguin II in battle with the Norse assaulting Bordeaux and Saintes. He himself had to fight the Vikings and died during an attack on Bordeaux in 848. He was the last Frankish-appointed duke. After his death, the Basque chief Sancho Sánchez probably took control of Bordeaux and was soon recognised as duke.
