Guigues VIII of Viennois

Guigues VIII de la Tour-du-Pin (1309 – 28 July 1333) was the Dauphin of Vienne (then within the Holy Roman Empire) from 1318 to his death.

Only nine years of age when his father died, he succeeded under the regency of his uncle Henri Dauphin, the bishop-elect of Metz, which was exercised until 1323.

French influence was reinforced during his reign, especially by his marriage to Isabelle, daughter of Philip V of France.

In 1328, at the Battle of Cassel, Philip VI entrusted to Guigues the command of the Seventh Corps, with its twelve banners.

For his courage, Guigues was rewarded with the Maison aux Piliers in Grève, Paris.
