カノッサの屈辱
Already in January, Henry hastened to see the pope on his way to the Empire from Rome. Duke Rudolf attempted to have the Alpine passes closed, nevertheless the king through wintry weather made his Walk to Canossa, where Gregory, fearing an armed attack by Henry's forces, had found refuge with Matilda of Tuscany. By doing penance, Henry managed to achieve absolution, buying time at the price of his reputation and secular authority. The rebels continued with their plans. Rudolf was elected anti-king on 15 March 1077 at the "Kaiserpfalz" in Forchheim, where already Louis the Child and Conrad I of Germany had been crowned. The first anti-king in the history of the Empire, he promised to respect the investiture solely according to canon law, as well as the concept of the elective monarchy. Further claims raised by the princes were rejected as simony by the attendant papal legates.
