Protestant Reformation and its impact on the Catholic church. In simple English term for easy to understand?

The Protestant Reformation was a movement in the 16th century that led to the creation of Protestant churches separate from the Catholic Church. This had a big impact on the Catholic Church, causing it to lose followers and power. The Reformation also led to changes within the Catholic Church, such as the Council of Trent, which addressed some of the issues raised by the Protestants. Overall, the Protestant Reformation changed the religious landscape in Europe and had lasting effects on the Catholic Church.
