The Road to Canossa or Humiliation of Canossa, or, sometimes, the Walk to Canossa was the journey of the Holy Roman Emperor Henry IV to Canossa Castle in 1077, and his subsequent ritual submission there to Pope Gregory VII. It took place during the Investiture controversy and involved the Emperor seeking absolution and the revocation of his excommunication by the Pope who had been staying at the castle as the guest of Margravine Matilda of Tuscany.

Henry IV, Holy Roman Emperor
Henry IV was Holy Roman Emperor from 1084 to 1105, King of Germany from 1054 to 1105, King of Italy and Burgundy from 1056 to 1105, and Duke of Bavaria from 1052 to 1054. He was the son of Henry III, Holy Roman Emperor—the second monarch of the Salian dynasty—and Agnes of Poitou. After his father's death on 5 October 1056, Henry was placed under his mother's guardianship. She made grants to German aristocrats to secure their support. Unlike her late husband, she could not control the election of the popes, thus the idea of the "liberty of the Church" strengthened during her rule. Taking advantage of her weakness, Archbishop Anno II of Cologne kidnapped Henry in April 1062. He administered Germany until Henry came of age in 1065.
