The Protestant Reformation: Crash Course European History #6

Summary

The video explains how resistance to the Catholic Church’s authority in the early 16th century developed into the Protestant Reformation. Religious arguments about salvation and scripture became intertwined with political struggles over power, wealth, and local rule. The movement spread through print, fractured into competing forms of Protestantism, and led to conflict that the Peace of Augsburg temporarily contained—but did not end.

Main Ideas and Developments

Why the Church Faced Resistance

The Catholic Church wielded authority through the papacy, religious courts and law, local clergy, and a large bureaucracy. Its teachings also reinforced social and political hierarchy, including the idea that monarchs and nobles were closer to God than ordinary people.

Discontent grew among people who objected to Church practices, its wealth, and its influence over everyday life.

Martin Luther’s Objections

Luther, a German monk and former law student, worried about salvation. He rejected the idea that salvation depended on both faith and good works, arguing instead that it came through faith alone.

He also opposed the sale of indulgences—payments said to release souls from purgatory. A special indulgence issued in 1517 helped raise money for St. Peter’s Basilica. Luther and other critics saw the practice as exploiting people’s grief and fear.

In 1517, Luther composed the Ninety-Five Theses, raising questions and objections about Church teaching. The video notes that they may have been posted on a church door, while emphasizing that their ideas spread regardless. Luther’s criticism eventually widened into a rejection of the Church’s authority as it operated at the time.

Luther’s Central Principles

Luther’s central principles included:

• Sola fide: salvation through faith alone.
• Sola gratia: salvation through grace alone.
• Sola scriptura: scripture, rather than priests or the Church hierarchy, is the ultimate religious authority.

Luther argued that priests, bishops, cardinals, and popes were human and fallible, and therefore should not serve as necessary intermediaries between people and God. His emphasis on scripture encouraged wider reading and individual study, rather than leaving biblical interpretation solely to clergy.

Luther’s Confrontation with Imperial Authority

Pope Leo X excommunicated Luther in 1521. At the Diet of Worms, Emperor Charles V demanded that Luther answer for his views; Luther reportedly refused to recant.

Charles declared Luther an outlaw, but the Saxon elector Frederick the Wise protected him. The video suggests Frederick may have been concerned about papal abuses, the fairness of Luther’s trial, or the emperor’s growing power. German princes later organized the Schmalkaldic League to defend Protestant interests.

Print and Political Motivations

Luther translated the New Testament into German, the vernacular rather than elite Latin. The printing press enabled large-scale circulation of this translation and his other writings, helping the Reformation grow from a local dispute into a German and then European movement.

Some princes supported reform not only for religious reasons but also as a way to limit the Holy Roman Emperor’s authority. Luther’s appeal to German identity contributed to his association with German nationalism.

Limits of Luther’s Support for Reform

In 1525, peasants and other villagers in southern Germany revolted, attacking castles and religious centers. The video estimates that about 100,000 people took part.

The princes and nobility crushed the uprising. Luther condemned the rebels in a pamphlet later published under the title Against the Murderous, Thieving Hordes of Peasants. This episode shows that Luther supported religious reform but not broad social upheaval or equality for peasants.

The Reformation Splinters into Different Movements

Swiss priest Ulrich Zwingli supported many of Luther’s criticisms of the papacy but disagreed with him about communion:

• Catholic doctrine: The bread and wine literally become Christ’s body and blood (transubstantiation).
• Luther’s view: The bread and wine remain bread and wine while also being Christ’s body and blood (consubstantiation).
• Zwingli’s view: Communion is symbolic; the bread and wine remain bread and wine.

Some of Zwingli’s followers became Anabaptists, who stressed individual faith and free choice. They argued that baptism should be reserved for adults who could consciously choose Christian faith, rather than performed on infants.

Marriage and Changing Religious Practice

Luther married Katharina von Bora in 1525, despite the Catholic expectation that clergy remain celibate. He argued that marriage and procreation were part of God’s plan. His support for marriage, and his writing about marital property, challenged established clerical norms.

The video also notes that Luther’s views of marriage did not amount to equality as understood today.

War and the Peace of Augsburg

Charles V tried to defeat the Protestant princes of the Schmalkaldic League in 1546–47. His forces initially defeated them and captured Protestant leaders. The League returned to the field in 1552 and defeated imperial forces.

The Peace of Augsburg in 1555 established that a territory’s ruler would determine its religion, making communities Catholic or Protestant according to their prince. This settlement did not resolve the wider religious conflict. The video closes by noting that further bloodshed would follow as theological differences, political rivalry, and overseas empire continued to interact.
