The council of trent was held amid chaos created by the reformation and counter-reformation movements. who set forth reforms for the catholic church at the council?

The Council of Trent, the 19th ecumenical council of the Roman Catholic church, was held at Trent in northern Italy between 1545 and 1563. It marked a major turning point in the efforts of the Catholic church to respond to the challenge of the Protestant Reformation and formed a key part of the Counter-Reformation. The need for such a council had long been perceived by certain church leaders, but initial attempts to organize it were opposed by Francis I of France, who feared it would strengthen Holy Roman Emperor Charles V, and by the popes themselves, who feared a revival of Conciliarism. The council eventually met during three separate periods (1545-47, 1551-52, 1562-63) under the leadership of three different popes (Paul III, Julius III, Pius IV). All of its decrees were formally confirmed by Pope Pius IV in 1564
