Robert V, Count of Auvergne

Robert V (c. 1225–1277) succeeded his father William X as count of Auvergne in 1247, ruling the reduced county. Through his mother Adelaide of Brabant he received Boulogne in 1260. After he imprisoned a monk over Saint-Germain-Lembron abbey, Pope Alexander IV excommunicated him.

In 1253 the bishops of Auvergne called in Alphonse of Poitiers against him. Robert sent a noble embassy to protest the royal investigations, then accepted a mediated settlement in 1254. He made his will on 11 January 1277 and died days later, leaving Auvergne and Boulogne to his elder son William XI.
