Study guide
In 1517, Martin Luther posted his 95 Theses criticizing the sale of indulgences (payments to reduce punishment for sins). Luther taught salvation by faith alone, the authority of the Bible alone, and the priesthood of all believers. Supported by German princes and spread by the printing press, Lutheranism took hold in northern Germany and Scandinavia. The Peace of Augsburg (1555) let each German prince choose Lutheranism or Catholicism for his territory (cuius regio, eius religio).
John Calvin, in Geneva, taught predestination: God has already chosen who will be saved. Calvinism spread to the Netherlands, Scotland (Presbyterians), France (Huguenots) and England (Puritans). In England, Henry VIII broke with Rome when the pope refused to annul his marriage, creating the Church of England with the Act of Supremacy (1534). Elizabeth I later established a moderate Protestant settlement. Radical groups like the Anabaptists rejected infant baptism.
The Catholic Church responded with the Catholic (Counter-) Reformation. The Council of Trent (1545–1563) reaffirmed Catholic doctrine while ending abuses, the Jesuits (founded by Ignatius of Loyola) spread Catholicism through education and missions, and the Index of Prohibited Books banned heretical works. Religious wars followed. In France, the conflict between Catholics and Huguenots included the St. Bartholomew's Day Massacre (1572) and ended with the Edict of Nantes (1598), which granted Huguenots toleration. The Thirty Years' War (1618–1648) devastated the Holy Roman Empire; the Peace of Westphalia (1648) recognized Calvinism, weakened the emperor and established the principle of state sovereignty.
Philip II of Spain, a champion of Catholicism, faced the Dutch Revolt beginning in 1566. The mostly Calvinist northern provinces resisted his taxes and religious persecution and became the independent Dutch Republic, formally recognized in 1648. His Spanish Armada failed to invade Protestant England in 1588. Because the Peace of Augsburg left out Calvinists, tensions grew, and in 1618 Bohemian Protestants revolted against Habsburg rule (the Defenestration of Prague). Catholic France under Cardinal Richelieu later fought on the Protestant side against the Habsburgs, which showed that state interests had begun to outweigh religion. Armies living off the land spread famine and disease and killed a large share of the population in parts of Germany.
Henry IV, a Huguenot, converted to Catholicism to secure the French throne and then issued the Edict of Nantes. He and other politiques put political stability ahead of religious unity. In the German Peasants' War (1524–1525), peasants cited Luther's ideas, but Luther sided with the princes who crushed them. Protestants closed convents, praised marriage and family life, and promoted Bible reading and literacy. Witch hunts, mostly targeting women, peaked in the late 1500s and 1600s.
England became more Protestant under Edward VI, and Mary I restored Catholicism and executed Protestants. Elizabeth I's 1559 settlement then made the Church of England moderately Protestant, with the monarch as its head. Mannerism, with elongated figures and emotional tension, followed the High Renaissance. The dramatic, grand Baroque style, seen in the work of Bernini and Rubens, was promoted by the Catholic Church to inspire devotion and by absolute monarchs to display their power.
