who were the main leaders of the reformation
The Reformation, specifically referred to as the Protestant Reformation, was a schism in Western Christianity initiated by Martin Luther and continued by John Calvin, Huldrych Zwingli, and other early Protestant Reformers in 16th-century Europe. It is usually considered to have started with the publication of the Ninety-five Theses by Martin Luther in 1517 and lasted until the end of the Thirty Years' War with the Peace of Westphalia in 1648.
