The Counter-Reformation, a Catholic response to the Protestant Reformation and earlier reformist movements, arose as a broad initiative to revitalize the Church through theological, spiritual, and structural changes. Initiated by the Council of Trent (1545–1563), it focused on doctrinal precision, anti-corruption efforts, and the renewal of religious life through new orders such as the Jesuits and spiritual movements emphasizing personal piety.
While historians continue to debate its exact timeframe, the era witnessed the establishment of seminaries, the reinforcement of sacramental traditions, and an effort to reclaim areas that had shifted to Protestantism. Although the term "Counter-Reformation" has faced criticism for portraying Catholic renewal solely as a reaction, it highlights a vibrant period of theological defense and artistic expression, distinct yet connected to the wider Catholic Reformation.
