Which key figure in medieval culture introduced important reforms to the Roman Catholic Church in the eleventh century?

Answer 1

The key figure in medieval culture who introduced important reforms to the Roman Catholic Church in the eleventh century was Pope Gregory VII. Pope Gregory VII, also known as Hildebrand of Sovana, is best known for his efforts to purify and centralize the Church, which became known as the Gregorian Reforms. These reforms aimed to combat simony (the buying and selling of Church offices), lay investiture (the appointment of bishops by secular rulers), and clerical celibacy violations. Pope Gregory VII's efforts had a significant and long-lasting impact on the structure and power dynamics within the Roman Catholic Church.
