Bianca of Savoy (1337– Pavia, 31 December 1387) was Lady of Milan by marriage to Galeazzo II Visconti.
In an attempt to curb the expansionist policies of Bianca's uncle John II, Marquess of Montferrat, an alliance was established on the 22 October 1349 between Amadeus VI, Count of Savoy and Giovanni Visconti of Milan.
Only weeks after the marriage in October 1350, Galeazzo was asked by his uncle to seize the city of Bologna but his fragile health forced him to leave the conquest.
In 1360 Galeazzo was appointed Imperial vicar by Charles IV, Holy Roman Emperor and Pavia fell under the domination of the Visconti family.
When war broke out between Milan and her uncle John II, on the side of the latter was Bianca's brother, Count Amadeus VI.
[8] In the last years of life, Bianca spent time raising her granddaughter, Valentina, whom she taught French and German.
