What happened
The Investiture Controversy, a conflict running from 1076 to 1122, pitted the German king (and Holy Roman Emperor) Henry IV against a succession of popes over who had the right to appoint bishops and abbots: the king, who invested them with the symbols of their office, or the pope. In 1076 Pope Gregory VII excommunicated Henry after Henry tried to depose him. Facing rebellion from German princes who used the excommunication as an excuse to move against him, Henry traveled to the castle of Canossa in northern Italy in January 1077 and, according to contemporary accounts, waited outside the gate for three days in winter weather, doing penance, before Gregory lifted the excommunication.
Why it matters
Canossa became the symbol, for centuries afterward, of the tension between German royal authority and papal power, a tension that ran through the rest of the empire's history. The underlying dispute over investiture was not actually settled at Canossa. It dragged on until 1122, when the Concordat of Worms split the difference by letting the church choose bishops while the emperor retained a say over their secular authority.
How we know
The events at Canossa are described by contemporary and near-contemporary chroniclers on both sides of the conflict, and historians note the confrontation has since become a byword in German for humiliating submission, so much so that Otto von Bismarck declared centuries later, during his own fight with the Catholic Church, that he would not go to Canossa.
