To what extent was the Catholic Church reformed between 1517 and 1563?

Candidates are expected to consider the merits or otherwise of the view that the Catholic Church was reformed between the years 1517 and 1563 (the end of the Council of Trent). They may take the approach of identifying the perceived problems within the Church to give some context. However, the focus must be on the attempts to reform the Church and how far they were successful. Candidates may focus on the activities of reforming groups such as the Capuchins, Jesuits and Ursulines as well as the initial reluctance of some in the papal hierarchy to introduce reform. Some candidates may note that, despite pressure from the emergence of Protestantism and pressure from Charles V, it was not until 1545 that the Council of Trent convened for the first time. The key conclusions of the Council of Trent—in terms of doctrine and Church organizations, both at a diocesan level and within the papacy—may be cited as evidence of reform.
