Page "Conrad IV of Germany" Paragraph 3

When Frederick II deposed his eldest son, Conrad's rebellious older brother Henry, in 1237 had Conrad elected King of the Romans in diet in Vienna.

This title presumed a future as Emperor of the Holy Roman Empire.

Archbishop Siegfried III of Mainz acted as German regent until 1242, when Frederick chose Henry Raspe, Landgrave of Thuringia, and Wenceslaus I of Bohemia, to assume this function.

Conrad intervened directly in German politics from around 1240.
