Council of Trent
Pope Paul III saw that the Protestant Reformation was getting bigger. Before, a small number of priests were part of the reformation, but soon many princes, particularly in Germany, supported its ideas. Therefore, Pope Paul III desired a council. But the council could not meet until 1545 and met right before Martin Luther's death. The council was moved to Bologna in March 1547 with the excuse of avoiding a plague; without any plans to meet again, 17 September 1549.
