It saw a cultural resurgence with the construction of iconic religious edifices and the transformation of visual arts, reinforcing the Church's authority and message.
Step-by-step explanation:
Rome was central to the Counter-Reformation and played a significant role during the Reformation. During the Counter-Reformation, the city saw a resurgence of religious and cultural activity, including the building of the new St. Peter's Basilica, which embodied the Catholic Church's renewed confidence and authority. Rome's response to the Reformation included ecclesiastical reconfigurations, the formation of new religious orders like the Jesuits, spiritual movements, and political reform to address both the challenges posed by Protestantism and internal issues within the Catholic Church. The Council of Trent played a critical role in affirming Catholic doctrines and initiating church reforms. Additionally, the visual arts in Rome, supported by the Church as the major patron, underwent a transformation as artists like Michelangelo portrayed biblical stories in new ways that communicated the Church's message more clearly and effectively. The ambition to rebuild Rome with grandeur took shape through monumental architecture and urban planning, symbolizing the power and piety of the Catholic Church post-Reformation.
