Reforms of the Catholic Church initiated by Pope Gregory VII c. 1050-80
Not to be confused with Gregorian calendar.
This article may be confusing or unclear to readers. In particular, not all reforms discussed in this article were initiated by Gregory VII. This article could be improved by a more clear and accurate chronology, equal discussion of the key figures involved (such as Pope Nicholas II), and more robust contextualization. The term "Gregorian Reform" is widely used but somewhat misleading (a possible source of confusion), as Gregory VII was an important, but not the sole, pope to make reforms in this period. Please help clarify the article. There might be a discussion about this on the talk page.(March 2022) (Learn how and when to remove this template message)

The Gregorian Reforms were a series of reforms initiated by Pope Gregory VII and the circle he formed in the papal curia, c. 1050–80, which dealt with the moral integrity and independence of the clergy. The reforms are considered to be named after Pope Gregory VII (1073–85), though he personally denied it and claimed his reforms, like his regnal name, honoured Pope Gregory I.
