Renaud I of Forez

Renaud I (1226–1270) was count of Forez from about 1260, succeeding his childless elder brother Guigues V. He was the younger son of Count Guigues IV and Matilda of Courtenay, and in 1247 he married Isabelle of Beaujeu, a widow whose dower brought him several lands.

After Guichard V of Beaujeu died in 1265 he claimed Beaujeu in his wife's name. Other lords contested the succession, which was settled only in 1269, when King Louis IX recognised Isabelle's rights. His eldest son Guigues VI succeeded him in Forez; another son, Louis, inherited Beaujeu.
