Guigues VI of Forez

Guigues VI of Forez (died 1278) was the son of Count Renaud I and Isabelle of Beaujeu. In 1268 he married Joan of Montfort, daughter of the count of Castres, and the following year King Louis IX recognized the rights of Isabelle and her children to Beaujeu.

Guigues succeeded his father as count of Forez in 1270 and claimed Beaujeu through his mother, but ceded it to his younger brother Louis. He died in 1278 leaving a minor heir, John I, who ruled under the regency of Joan of Montfort.
