11/18/1210 AD excommunicated

Otto infuriates Innocent, with the following actions, and is promptly excommunicated.

• He threw the papal troops out of Ancona and Spoleto, reclaiming the territory as imperial fiefs
• He then demanded that Frederick of Sicily do homage for the duchies of Calabria and Apulia, and when Frederick refused to appear, Otto declared those fiefs forfeited.
• He then marched on Rome, and commanded Innocent to annul the Concordat of Worms, and to recognise the imperial crown's right to make nominations to all vacant benefices.

So while Otto was in southern Italy, several princes of the empire, including the archbishops of Mainz and Magdeburg, at the instigation of King Philip II of France and with the consent of the pope, elected Frederick King of the Romans at the Diet of Nuremberg in 1211.
