1097 CE
Emperor Henry IV had attempted to reverse his fortunes by seizing Matilda's castle of Nogara in 1095, but the countess's arrival at the head of an army forced him to retreat.
In 1097, Henry withdraws from Italy altogether, after which Matilda reigns in Tuscany virtually uncontested, although she will continue to launch military operations designed to restore her authority and regain control of the towns that had remained loyal to the emperor.
