Galeazzo's distinction and authority over different city-states was crucial in helping fund military campaigns against the papacy and in helping to perpetuate his rule over north Italy. The financing of military expeditions was dependent on taxation of Galeazzo's city-states, some of which included Milan and Pavia, which he claimed in 1359 and made the primary residence of the Visconti family. However, multiple wars, heavy taxation and refusal to align with the papacy generated disapproval amongst Galeazzo's subjects. Inconsistent and costly governance caused resistance against Galeazzo II's rule.
