Galeazzo II's rule would serve to set up Gian Galeazzo Visconti's rule of Pavia. It is immediately evident just how influential the father had been on his son. It is thought that Galeazzo II and his brother, Bernabò Visconti, came to rule after successful plot against their third brother, Matteo II. Very much in the same vein, Gian Galeazzo was able to mastermind a coup d'état against Bernabò, his uncle. This bloody legacy of homicide, at first taking the form of fratricide, and then avunculicide, is a large part of the Visconti legacy forged by Galeazzo II. Yet another legacy of Galeazzo II Visconti with his son is the importance placed on education. Gian Galeazzo, upon ascending to the throne at Pavia, remains content to study, retreating from the mess of Italian politics in Northern Italy, and focussing on his Humanist studies at the University of Pavia; the same University which his father had set up when he moved his seat of power there. The final Visconti legacy passed from father to son is that of embarking upon massive building projects. For Galeazzo II, this was the massive palace he constructed at Pavia, which was completed for him in 1363. For his son Gian Galeazzo, this tendency to build as a means of impressing the populace continues. Gian Galeazzo Visconti commissioned the construction of the Certosa of Pavia and provided help and counsel in the construction of the Duomo in Milan when he became Signore of all Milan, following the overthrow of Bernabò Visconti.
