In June 1075, Henry won a victory over the rebellious German princes with the help of his cousin Rudolf, duke of the German region of Swabia. He recognized that the German nobles wanted to challenge his power and would encourage a conflict between the pope and himself. He relayed this information to the pope, but in November 1076, he appointed a high church official himself in direct violation of the pope's order. This resulted in a letter from Gregory that threatened Henry's excommunication, or removal from the church.
Like her mother before her, Matilda had sought to strengthen her position through marriage, in her case to her stepbrother Godfrey the Hunchback in 1069. The purpose of this marriage was political, and after her infant son died in 1071, she returned to Italy. Godfrey died in 1076, but she remarried in 1089, once again for political reasons. This time the groom was Welf V, a German duke who supported the new pope, Victor III, against Henry. By this time she was forty-three, and Welf only seventeen.

Matilda enjoyed a much closer relationship with Henry V, son of Henry IV, than she had with his father. But when she died in 1115, leaving no heirs, Henry V claimed most of her lands. She was later celebrated in a long poem by Donizo, her chaplain at Canossa.
Angered by the pope's letter, in January 1076 Henry called together twenty-four bishops in the German city of Worms (VURMZ), and they sent a letter of protest to the pope. Along with this letter, Henry sent one of his own that called the pope "a false monk." This in turn enraged Gregory, who on February 22 issued orders declaring that Henry was excommunicated and damned to hell; furthermore, the people of his kingdom were forbidden from submitting to him.
