On April 21, 1073, Pope Alexander II died. Soon afterward Hildebrand, who had become immensely popular among the people of Rome, was elected pope by the cardinals, the highest officials within the church other than the pope himself. In honor of Gregory VI, he chose the title Gregory VII.
Gregory set about reforming the church, which had long been in decline. Not only could church offices be bought and sold, but increasingly more corrupt men had taken positions of power, thus weakening the moral authority of the pope and other church leaders. With the church in a shambles, Gregory was determined to put it back on the right course—and to show the Holy Roman emperor who was boss.
For many years, emperors had been investing, or appointing, bishops within the church. On February 24, 1075, however, Gregory issued orders banning lay investiture, or appointment of bishops by leaders outside the church. Not long afterward, he put down on paper a list of twenty-seven key points about the papacy, or the office of the pope: for instance,
Matilda of Tuscany
Though she was related to Emperor Henry IV, Matilda of Tuscany (c. 1046-1115) took part in the Investiture Controversy on the side of Pope Gregory VII. Her family had long controlled lands in northern Italy, including Canossa, site of the castle where Gregory and Henry had an important meeting in 1077.
Matilda was raised in an unconventional way for a young girl of the Middle Ages, receiving the sort of comprehensive and wide-ranging education that was normally set aside only for boys. Clearly she was being groomed for leadership, and upon the death of her father and brother in 1052, Matilda became countess of Tuscany.
Knowing that neighboring princes might want to invade a region "ruled" by
A six-year-old girl, her mother married Godfrey, duke of Lorraine (a region on the border between France and Germany.) However, Godfrey was in conflict with Emperor Henry III of Germany, who imprisoned both mother and daughter from 1055 to 1056.
No doubt as a result of this experience, Matilda was no supporter of her German cousins. Furthermore, she became closely involved in church affairs, and her family were close friends with the future Pope Gregory VII. Therefore when the Investiture Controversy between Henry IV and Gregory VII came to a head, Matilda sided with Gregory. Nonetheless, the fact that she was related to Henry made her a natural go-between for the two opposing sides.
He wrote that no one had the right to question the pope's actions, and that kings and princes should kiss the pope's feet.
