Rupert of the Palatinate vs Sigismund I the Old

The four Rhenish electors deposed Wenceslaus IV and elected Rupert of the Palatinate as King of the Romans. Rupert's election was contested by Wenceslaus and his supporters, leading to a divided empire. Rupert was never crowned Holy Roman Emperor by the Pope.

Rupert led an expedition to Italy to secure his coronation as Holy Roman Emperor and to support Pope Boniface IX against his rivals. The campaign was a failure; Rupert's army was defeated by the forces of Gian Galeazzo Visconti of Milan near Brescia. Rupert retreated to Germany without achieving his goals.

Rupert became embroiled in a conflict with Archbishop Johann II of Mainz over the election of a new bishop in the diocese of Paderborn. The dispute escalated into a military confrontation, with Rupert besieging the archbishop's castle. The conflict was eventually resolved through mediation, but it weakened Rupert's authority.

Sigismund I the Old, as a young prince, participated in the Hussite Wars, leading Polish forces in support of the Hussites. This involvement exposed him to military and religious conflicts that shaped his later policies.

Sigismund I the Old was crowned King of Poland after the death of his brother Alexander. His reign marked the beginning of the Polish Golden Age, characterized by cultural flourishing and political stability.

Sigismund I the Old married Bona Sforza of Milan, bringing Italian Renaissance culture to Poland. He commissioned the renovation of Wawel Castle in Renaissance style and invited artists like Francesco Fiorentino, making Krakow a center of Renaissance art.

Sigismund I the Old fought a war against the Teutonic Order under Grand Master Albrecht von Hohenzollern. The conflict ended with a truce in 1521, leading to the secularization of the Order and the creation of the Duchy of Prussia as a Polish fief.

Sigismund I the Old faced the Execution of the Laws movement, which demanded the return of royal lands illegally held by nobles and the codification of laws. He resisted these demands, leading to tensions with the nobility that continued into his son's reign.
