The Counter-Reformation was a period of Catholic resurgence in response to the Protestant Reformation, which began in the early 16th century. The Protestant Reformation, led by figures such as Martin Luther and John Calvin, challenged the authority of the Catholic Church and led to the establishment of new Protestant denominations.
The Counter-Reformation was initiated by the Catholic Church in the mid-16th century as a response to the spread of Protestantism. The Council of Trent, held between 1545 and 1563, was a key event in the Counter-Reformation. The council reaffirmed Catholic doctrine, addressed issues of corruption and abuse within the Church, and established new guidelines for the education and training of clergy.
The Counter-Reformation also saw the establishment of new religious orders, such as the Jesuits, who played a key role in spreading Catholicism and combating Protestantism. The Catholic Church also engaged in efforts to reform and revitalize its institutions, promote education and literacy, and combat heresy through the Inquisition.
The Counter-Reformation had a significant impact on European society and politics, leading to religious conflicts and wars, such as the Thirty Years' War. It also had a lasting influence on the development of Catholicism and the modern world.
