According to some historians, Bianca was the only true love of Frederick's life; others consider this a romantic exaggeration. It was certainly beneficial to the interests of the Lancia family, who were favoured by the Emperor with political posts in Italy (Manfredo III was appointed Imperial Vicar of the Holy Roman Empire's northern Italian territories and Podesta of Alessandria, Milan and Chieri; Galvano became Imperial Vicar of Tuscany, Podesta of Padova, Prince of Salerno, Count of Fondi and Grand Marshal of Sicily; and Frederick was appointed Count of Squillace and Viceroy of Apulia). Nonetheless, the relationship of Bianca and Frederick was the longest to all the affairs of the Emperor.
