Manfred I of Turin
Manfred was the eldest son of Arduin Glaber, from whom he inherited the county of Auriate and the vast March of Susa. The march extended from the Susa Valley by the Alps south across the Po to the Ligurian Sea. Although he ruled for almost twenty-five years, there is little evidence of his activities in surviving sources. Under him, Pavia became a mercantile city. He also controlled the road between Genoa and Marseilles.
