Indulgences

Remissions of temporal punishment for sin, sold to fund building projects including St Peter's. The immediate trigger of Luther's protest and the clearest example of the abuses reformers named.

Ninety-Five Theses

1517. Luther's objections to indulgences, intended as an academic disputation. The printing press turned a scholarly complaint into a movement within weeks.

Martin Luther

German monk whose doctrines of justification by faith alone, scripture alone and the priesthood of all believers denied the Church's mediating role. Excommunicated in 1521.

Justification by faith alone

Salvation comes through faith, not works or sacraments. Removing works removed the theological basis of indulgences, pilgrimages and much of the Church's authority.

Sola scriptura

Scripture alone is authoritative, not tradition or papal pronouncement. It made vernacular Bible translation essential and made literacy a religious question.

Diet of Worms

1521. Luther refused to recant before Charles V and was declared an outlaw. Frederick the Wise sheltered him, showing how princely politics protected the Reformation.

Why German princes supported Luther

Religious conviction, resentment of payments to Rome, and the chance to seize Church lands and assert independence from the Emperor. Faith and interest pointed the same way.

German Peasants' War

1524–25. Peasants invoked Luther's language of Christian freedom against feudal dues. Luther condemned them fiercely, which fixed the Reformation as a movement allied to established authority.

John Calvin

Reformer whose Institutes of the Christian Religion systematized Protestant theology around God's sovereignty and predestination. His Geneva became the model and training ground for reformers across Europe.

Predestination

The doctrine that God has already determined who will be saved. It produced not fatalism but disciplined striving, since worldly success and moral conduct were read as signs of election.

English Reformation

Begun by Henry VIII for dynastic and political reasons rather than doctrinal ones. The Act of Supremacy (1534) made the monarch head of the English Church, and monastic lands were sold to the gentry.

Elizabethan Settlement

Elizabeth I's middle way: Protestant doctrine with retained Catholic ceremony and structure. Designed for political stability rather than theological purity, and it largely delivered it.

Anabaptists

Radical reformers rejecting infant baptism and often civil authority. Persecuted by Catholics and Protestants alike, which shows how narrow the limits of toleration were.

Catholic (Counter) Reformation

The Catholic response: doctrinal reaffirmation at Trent, new religious orders, reformed clergy training, and the Index and Inquisition. Reform and repression together.

Council of Trent

1545–63. Reaffirmed transubstantiation, the seven sacraments, tradition alongside scripture, and salvation by faith and works. It also ended the sale of indulgences and required seminaries.

Jesuits

The Society of Jesus, founded by Ignatius Loyola in 1540. Militarily disciplined, focused on education and missions, and the most effective instrument of Catholic recovery in central Europe.

Peace of Augsburg

1555. Each German prince chose Lutheranism or Catholicism for his territory — cuius regio, eius religio. Calvinism was excluded, which left a grievance that helped cause the Thirty Years' War.

French Wars of Religion

1562–98. Catholic and Huguenot factions fought amid a weakened monarchy. The St Bartholomew's Day Massacre of 1572 is the standard evidence of their brutality.

Edict of Nantes

1598. Henry IV granted Huguenots limited toleration and fortified towns, ending the wars. His conversion to Catholicism — "Paris is worth a Mass" — is the standard example of politique reasoning.

Politiques

Rulers who subordinated religious uniformity to political stability. Henry IV and Elizabeth I are the examples, and they mark the beginning of religion ceasing to determine policy.

Thirty Years' War

1618–48. Began with the Defenestration of Prague as a religious conflict in the Empire and ended as a dynastic struggle, with Catholic France fighting the Catholic Habsburgs.

Peace of Westphalia

1648. Recognized Calvinism, granted German princes near-sovereignty, and confirmed Dutch and Swiss independence. Conventionally the start of the modern sovereign-state system and the end of religion as a cause of major European war.

Effects of the Reformation on women

Convents closed in Protestant lands, removing the main institutional alternative to marriage, while the pastor's wife became a new model. Literacy rose with Bible reading. The net effect is genuinely debated and an essay can argue either way with evidence.

Simony, pluralism and absenteeism

The three abuses reformers named most often: buying church office, holding several benefices at once, and drawing an office's income without residing in it. They are the concrete grievances behind the theological argument, and naming them is more persuasive on an exam than "corruption."

Consubstantiation vs transubstantiation

Catholic transubstantiation holds that the bread and wine become the body and blood of Christ in substance. Luther's consubstantiation holds that Christ is truly present alongside bread and wine that remain what they are. Calvin held the presence to be spiritual, Zwingli purely symbolic — and this single question split the Protestant movement at Marburg in 1529.

The Consistory in Geneva

The body of pastors and lay elders that supervised morals in Calvin's Geneva, able to summon, admonish and exclude the unrepentant from communion. It gave Calvinism an institutional discipline Lutheranism lacked and a model exportable to congregations under hostile rulers.

Act of Supremacy (1534)

Made Henry VIII "the only supreme head on earth of the Church of England," transferring jurisdiction from the pope to the crown. It changed authority, not doctrine — the Six Articles of 1539 reaffirmed transubstantiation and clerical celibacy on pain of death.

Dissolution of the monasteries

Henry VIII's seizure of monastic property from 1536, which transferred enormous wealth to the crown and, crucially, was sold on to gentry buyers. That sale created a propertied class with a permanent financial interest in never returning to Rome, which is why Mary could restore the liturgy but not the lands.

Index of Prohibited Books

The Catholic list of forbidden titles, established in 1559 as part of the Counter-Reformation. Together with a reinvigorated Roman Inquisition it shows the Church using the printing press's own logic against it — controlling reading because reading was what had spread the Reformation.

Saint Bartholomew's Day Massacre (1572)

The killing of thousands of Huguenots in Paris and beyond, beginning with the assassination of Protestant leaders gathered for a royal wedding. It destroyed hopes of a negotiated settlement, hardened the French wars of religion, and made the politique argument — that the state must survive the confessional quarrel — thinkable.

Defenestration of Prague (1618)

Bohemian Protestant nobles threw two Habsburg regents from a castle window, triggering the Thirty Years' War. The point for an exam is what it symbolizes: a religious grievance in one province escalating into a continental war because dynastic and confessional alliances were entangled across the Empire.

Witch hunts in early modern Europe

Roughly 40,000–60,000 executions between about 1450 and 1750, some three-quarters of the accused women, peaking around 1560–1660 and concentrated in the fragmented Empire and Switzerland. Explanations combine religious anxiety, social stress from inflation and war, gendered suspicion of unattached women, and weak central judicial control.

Protestant literacy and schooling

If salvation comes through scripture, believers must read it — so Protestant territories pushed vernacular Bibles and town schools, Luther urging provision for girls as well as boys. The Jesuits answered with the best school system in Europe, leaving both confessions committed to mass education for competitive reasons.

What examiners penalize here

• For causation questions, weigh **religious and secular** motives together: genuine theological grievances combined with princes’ hunger for land and autonomy and the amplifying power of print. Strong answers show the Reformation as both a spiritual and a political revolution.
• When comparing the Protestant and Catholic Reformations, frame them as a **religious dialogue**: each Protestant idea (sola fide, sola scriptura, married clergy) met a Catholic counter-position at Trent. Pairing the claims and counter-claims shows analytical command.
• Social-history prompts reward specifics: link the Reformation to the **patriarchal nuclear family**, the loss of the convent option for Protestant women, rising **literacy**, and the gendered **witch craze**. Concrete social effects, not just theology, earn evidence points.
• A reliable comparison to have ready. **Lutheran**: salvation by faith, consubstantiation, church governed under princely authority, largely confined to German states and Scandinavia. **Calvinist**: predestination, spiritual presence in communion, church governed by pastors and elders with real independence from the state, international and frequently at war with its rulers.
• Use the Elizabethan Settlement whenever a question asks about religious toleration in the sixteenth century. It is not toleration in the modern sense — attendance was compulsory and recusants were fined — but it is a deliberate decision to require outward conformity while leaving conscience unexamined, and that distinction earns points.
