+1 and I wish I could give more for Canossa, that's really what is missing. From Wikipedia: "The Road to Canossa...refers to Holy Roman Emperor Henry IV's trek to Canossa Castle, Italy, where Pope Gregory VII was staying as the guest of Margravine Matilda of Tuscany, at the height of the investiture controversy in January 1077 to seek absolution of his excommunication. According to contemporary sources, he was forced to humiliate himself on his knees waiting for three days and three nights before the entrance gate of the castle, while a blizzard raged. Indeed, the episode has been described as "one of the most dramatic moments of the Middle Age" https://en.m.wikipedia.org/wiki/Road_to_Canossa https://en.m.wikipedia.org/wiki/Road_to_Canossa I also really enjoy Norman Cantor's description in "Civilization in the Middle Ages," where he takes a more cynical view of the actions involved.
