Answer:
The Counter-Reformation
Explanation:
In the mid-1500s, in response to the Protestant Reformation, the Catholic Church subjected itself to a process of change called the Catholic Counter-Reformation. On one hand, it eliminated the worst of its corruption. On the other, it reaffirmed the authority of the pope, gave new powers to the Holy Inquisition, and created an Index of Forbidden Books that remained in place until the 1960s.
