Guigues V of Albon

Guigues V (c. 1125 – 29 July 1162) was the Count of Albon and Grenoble (then part of the Holy Roman Empire) from 1142 until his death.

In that year Guigues took the reins of government and immediately set about to avenge his father, who had been killed in a surprise attack by the Count of Savoy, Amadeus III, during the siege of Montmélian eleven years earlier.

[2] Guigues V besieged Montmélian a second time, but was driven off by Humbert's relief force.

Two years later, on 13 January 1155, Guigues was in Rivoli, near Turin, to recognise the suzerainty of the Holy Roman Emperor, Frederick Barbarossa, for his lands.

[a] However, Usseglio has shown that Chorier had misdated a charter of Frederick II for one of Frederick I: the Beatrice of Montferrat in question was the daughter of William VI of Montferrat, and widow of Guiges V's grandson Guigues VI of Viennois.
