Eustache, Count of Valence

Eustache was bishop of Valence from 1107 and, in the charters, bishop and count of Valentinois, probably a kinsman of the rising house of Poitiers-Valentinois. That year he attended Pope Paschal II's synod at Lyon and received the pope at Valence.

Bernard of Clairvaux denounced his conduct in letter 185, accusing him of oppressing the faithful and squandering his church's wealth, and on 30 May 1135 Pope Innocent II deposed him at the council of Pisa. Eustache refused to submit, and Valence lay under interdict for seven years.

A charter of March 1138 styles him Eustachius episcopus et comes Valentinensis. He was driven from Valence by force around Easter 1141, and his death is placed after 1148 or 1154.
