Henry VI vs Rupert of the Palatinate

Henry VI was elected King of Germany in 1190 following the death of his father Frederick Barbarossa. He succeeded without opposition, inheriting a powerful Hohenstaufen realm.

Pope Celestine III crowned Henry VI Holy Roman Emperor in Rome on April 15, 1191. The coronation was delayed due to tensions with the Papacy over Henry's claims in Sicily.

Henry VI captured King Richard I of England in December 1192 near Vienna and held him for ransom. Richard was released in 1194 after payment of a huge ransom, which Henry used to fund his Sicilian campaign.

Henry VI conquered the Kingdom of Sicily in 1194 after the death of King Tancred. He was crowned King of Sicily in Palermo on December 25, 1194, uniting the island with the Empire and creating a vast Mediterranean domain.

Henry VI proposed a plan to make the Empire hereditary and to launch a crusade to conquer the Byzantine Empire. The plan failed due to opposition from German princes and Henry's sudden death in 1197.

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.
