The Protestant Reformation
Martin Luther's challenge split Western Christianity.
About this topic
The Reformation began in 1517 when Martin Luther, a German monk and professor, posted his Ninety-Five Theses criticizing the Catholic Church, especially the sale of indulgences, which promised reduced punishment for sins in return for money. Luther argued that salvation comes by faith alone and that the Bible, not the pope, is the highest authority, and he translated it into German.
The printing press spread his ideas, and German princes who wanted independence from the Church and the emperor supported him. Other reformers followed: John Calvin in Geneva taught predestination, Huldrych Zwingli in Switzerland, and in England Henry VIII broke with Rome in 1534 so he could annul his marriage, forming the Church of England. Protestants split into Lutherans, Calvinists, Anglicans and later Baptists and others.
The Catholic Church responded with the Counter-Reformation, including the Council of Trent, the Jesuits and the Inquisition. Religious wars followed, such as the Thirty Years' War (1618 to 1648), ended by the Peace of Westphalia. Effects included more literacy, challenges to authority and growing national states. A misconception is that the Reformation was only about religion; politics, money and power mattered, and it ended the religious unity of Western Europe.
