This guide is for Pearson Edexcel A-level History (9HI0), Paper 2, option 2B.1: Luther and the German Reformation, c1515–55. It is the depth study in Route B, Religion and the state in early modern Europe.

Pearson reorganised the content across all four 2B.1 key topics in Issue 4 of the specification, published in June 2026 for first teaching from September 2026. The historical course and assessment model remain recognisable, but students who began earlier may see topics arranged differently in school materials. Check the specification issue or teaching plan your school is using; do not assume that a different sequence means that a topic is irrelevant.

Paper 2 lasts 1 hour 30 minutes, carries 40 marks and contributes 20% of the A level. You answer:

• one compulsory 20-mark question on two primary sources, assessing AO2;
• one 20-mark essay, chosen from two, assessing AO1.

This is a depth study. You need precise knowledge of people, beliefs, institutions and turning points, but strong answers also explain how religious conviction interacted with print, government, war and princely power.

The whole course in one argument

Luther’s protest became a durable Reformation because ideas and power interacted. Criticism of clerical conduct, papal finance and indulgence preaching existed within a Church that remained socially powerful. Luther’s challenge widened from a dispute about indulgences into a rejection of papal authority and a new account of salvation. Print spread that challenge, but political protection kept Luther alive. After 1521, disagreement with radicals and the Peasants’ War moved Lutheranism closer to territorial rulers. Melanchthon, catechisms, worship, schools and princely church government then turned protest into institutions. Charles V could defeat Protestant forces but could not overcome the Empire’s negotiated constitution, his foreign wars or the princes’ interests. The Peace of Augsburg therefore recognised Lutheran survival in 1555 without creating religious freedom or restoring Christian unity.

1. Germany in c1515

The Holy Roman Empire

The Holy Roman Empire was not a single centralised German state. It was a layered political order of territories, ecclesiastical states, cities and lordships. The emperor possessed status and important legal and dynastic powers, but governed through negotiation with the Imperial Estates. Seven electors chose the ruler. Territorial princes exercised substantial authority within their lands, while the Imperial Diet provided a forum for bargaining and legislation.

This structure mattered twice. It made uniform action difficult because an imperial decision depended on cooperation across many jurisdictions. It also gave reform somewhere to become durable: a sympathetic prince or city council could protect preachers, reorganise worship and resist outside enforcement.

Maximilian I’s government had pursued reform through institutions including the Imperial Chamber Court, but the Empire was not becoming a modern centralised monarchy. Reform reflected exchange between ruler and Estates. When Charles V was elected in 1519, his authority remained impressive but negotiated.

Economy, society and communication

Germany contained prosperous commercial and manufacturing centres, especially in the south, alongside varied rural economies. Towns and cities grew, mining and metalworking expanded in some regions, and merchant families such as the Fuggers operated international financial networks. Agriculture remained fundamental, while peasants faced very different combinations of rents, dues, labour services and customary rights.

Trade routes and urban networks allowed people, books and arguments to travel, although communication was uneven. Printing presses were concentrated in towns. Rising literacy among clerics, officials and parts of the urban population helped create audiences for religious controversy, but most communication still depended on sermons, images, conversation and public reading.

The German Church and the Papacy

The Church was a religious institution, a major landholder and part of imperial politics. Prince-bishops possessed secular as well as spiritual authority. Parish clergy served local communities with widely varying education and effectiveness. Religious life included the Mass, sacraments, saints, confraternities, pilgrimage and charitable giving. Criticism of clergy did not therefore mean that Germans were waiting to become Protestant.

Complaints focused on clerical privilege, poor pastoral service, pluralism, absenteeism and Church wealth. Humanism encouraged the study of biblical languages, education and moral reform. Humanists were not automatically followers of Luther: Erasmus criticised abuses but did not accept Luther’s later break with Rome.

Papal taxes, appointments and financial demands could be presented as money leaving German lands. The indulgence preached by Johann Tetzel in 1517 was connected to St Peter’s Basilica and Archbishop Albrecht of Mainz’s financial obligations. An indulgence officially remitted temporal penalties attached to forgiven sin; it did not simply sell divine forgiveness. The mixture of devotional hope, forceful preaching and institutional finance made it explosive.

Section judgement

Germany in c1515 was neither on the verge of inevitable revolution nor politically incapable of reform. The Church remained embedded, but grievances were real. Political fragmentation, urban communication and disputed authority created conditions in which a local controversy could spread and survive.

Check your understanding

1. Why is it misleading to describe the Empire simply as weak?
2. How did German towns help religious ideas spread?
3. Why did anticlericalism not necessarily produce Protestantism?
4. Judge which mattered more in 1517: religious grievance or political structure.

2. Luther’s early challenge, 1517–21

Luther and the Ninety-Five Theses

Martin Luther was an Augustinian friar, preacher and professor of biblical theology at Wittenberg. Scripture, his religious order, Johann von Staupitz and anxiety about salvation shaped his thinking. Historians debate when his mature doctrine of justification developed, so avoid reducing his transformation to one sudden “tower experience”.

The Ninety-Five Theses of October 1517 proposed an academic debate about penance and indulgences. They were not a complete Lutheran programme. Luther also wrote to Albrecht of Mainz, challenging indulgence preaching and its pastoral consequences. Printing and translation took the controversy far beyond its intended academic setting. The famous story that Luther nailed the theses to the church door may be true, but the evidence is disputed and the argument does not depend on it.

From reform to a challenge to authority

At Augsburg in 1518, Cardinal Cajetan pressed Luther to submit. Luther increasingly questioned whether papal authority could settle the dispute. At Leipzig in 1519, Johann Eck linked Luther’s claims to Jan Hus and forced debate about the authority of popes and councils. The controversy was now about who could define Christian truth.

The imperial election of 1519 delayed decisive action and made German politics central. Frederick the Wise, Elector of Saxony, did not need to agree with every Lutheran claim to insist on lawful procedure and defend his university and territorial standing.

In 1520 Luther published three major works:

• To the Christian Nobility of the German Nation appealed to secular rulers to reform the Church;
• The Babylonian Captivity of the Church attacked the established sacramental system;
• The Freedom of a Christian explained the relationship between faith, freedom and service.

Luther’s doctrine of justification by faith alone placed saving trust in God’s promise rather than in human merit. Scripture became the decisive authority. These ideas altered the role of priesthood, sacraments and papacy. They also widened the distance between Luther’s position and reform within existing Catholic structures.

Excommunication and Worms

Pope Leo X’s bull Exsurge Domine condemned propositions in June 1520. Luther burned it. Decet Romanum Pontificem excommunicated him in January 1521.

At the Diet of Worms in April 1521, Luther refused a general recantation unless convinced by scripture and reason. The celebrated phrase “Here I stand” is not securely recorded in the earliest account. Charles V defended inherited Catholic order, and the Edict of Worms declared Luther an outlaw and prohibited his works.

Frederick arranged Luther’s concealment at Wartburg. The Edict was serious, but enforcement depended on rulers and governments across the Empire. Luther survived through an interaction of conviction, popularity, print, legal procedure, Frederick’s protection and Charles’s competing priorities. Print explains reach; it does not by itself explain survival.

2. Why was the Leipzig debate a turning point?
3. Explain the significance of the 1519 imperial election.

3. Lutheran beliefs and Luther’s leadership, 1521–46

Worms, Wartburg and Wittenberg

At Wartburg, Luther translated the New Testament into German. Translation and later revision were part of a larger programme of preaching and education, not proof that ordinary people suddenly became independent theologians.

During his absence, Andreas Karlstadt promoted rapid liturgical change in Wittenberg, while visitors associated with Zwickau brought more radical ideas. Luther returned in 1522. His Invocavit sermons rejected coerced reform and argued that preaching should lead change. This helped reassert his authority and distinguished his programme from religious radicalism.

Knights, peasants and political conservatism

The Knights’ Revolt of 1522–23 mixed religious language with status, territorial and personal grievances. Luther did not support it. The Peasants’ War of 1524–25 was broader and arose from varied local conflicts about lordship, dues, labour, justice and customary rights. The Twelve Articles connected some demands to the gospel, but there was no single rebel programme. Thomas Müntzer became important in Thuringia, not commander of every rising.

Luther initially criticised both oppressive rulers and rebellion. As violence escalated, he called for harsh suppression in Against the Robbing and Murdering Hordes of Peasants. His response damaged his standing among some ordinary Germans and associated Lutheran reform more closely with political order and princely protection. His conservatism reassured rulers, but Lutheranism did not become merely a cynical princely creation.

Belief, worship and education

Justification by faith remained central: salvation rested on divine grace received through faith, not accumulated merit. Luther accepted baptism and the Eucharist as sacraments in a distinctive sense and defended Christ’s real presence in the Eucharist, while rejecting the Catholic explanation of transubstantiation and the sacrificial character of the Mass.

The German Mass of 1526 reformed worship without making Latin or traditional forms disappear everywhere. Luther’s Bible translation, hymns and preaching widened access to teaching. The Large and Small Catechisms of 1529 supplied structured instruction for pastors, households and children. Visitations revealed weak knowledge among clergy and laity, showing why institutions mattered as much as pamphlets.

Melanchthon and confessional definition

Philipp Melanchthon was not merely Luther’s assistant. A humanist scholar, theologian, educator and negotiator, he systematised teaching in the Loci communes of 1521 and shaped schools and church visitations. He drafted the Augsburg Confession of 1530, a measured statement of Lutheran belief presented by specified princes and cities. The Catholic Confutation rejected crucial claims, and Melanchthon answered with the Apology.

The confession gave the movement a clearer public identity but did not secure legal recognition. Luther and Melanchthon sometimes differed in emphasis and tactics. The Philip of Hesse bigamy affair in 1540, in which reformers offered secret and damaging advice, exposed the political and moral risks of dependence on princely patrons.

Check your understanding

1. Why did Luther oppose Karlstadt, the knights and the peasants for different reasons?
2. How did the Peasants’ War change Lutheranism’s political position?
3. Why were catechisms and visitations essential to consolidation?
4. Assess Melanchthon’s importance independently of Luther.

4. The spread and survival of Lutheranism, 1521–55

Princes, Diets and alliance

Frederick the Wise protected Luther without formally converting. John of Saxony openly adopted Lutheran reform. Philip of Hesse gave energetic political support, while Albrecht of Hohenzollern secularised the Teutonic Order’s Prussian territory and adopted Lutheranism. Motives varied: conviction, dynastic interest, control of Church property and territorial authority could reinforce one another.

The Diet of Speyer in 1526 gave Estates temporary room to act while remaining answerable to God and emperor; it did not establish toleration. In 1529, six princes and fourteen cities protested against reversal, giving “Protestant” a political meaning. The Schmalkaldic League, founded in 1531, was a defensive alliance of Protestant rulers and cities. It protected members and helped Lutheran institutions develop, but it was neither a unified state nor free of internal rivalry.

Failed negotiation

Catholic and Lutheran beliefs diverged over authority, justification, sacraments, ministry and worship. At Regensburg in 1541, negotiators found a carefully worded formula on justification, showing that discussion was real. Agreement failed because other doctrines, political distrust and opposition on both sides remained. Negotiations delayed or reshaped conflict but could not erase the institutions and identities built since the 1520s.

The Papacy’s early response was slow and often legally or politically ineffective in Germany. Paul III later supported reform, commissioned the Consilium de emendanda ecclesia in 1537 and summoned the Council of Trent, which opened in 1545. These measures strengthened Catholic renewal but did not reunite the Empire.

Charles V’s priorities and the Schmalkaldic War

Charles V opposed Lutheranism, but he ruled a composite monarchy and faced war with France, Ottoman expansion, Mediterranean conflict and disagreement among Catholic princes. These pressures repeatedly limited concentration on Germany. This does not mean that Charles ignored the Empire; it means that imperial policy had to operate across several theatres and through negotiated institutions.

In the Schmalkaldic War of 1546–47, Charles defeated the League and captured major leaders after victory at Mühlberg. Yet military success did not settle religious belief or constitutional power. The Augsburg Interim of 1548 tried to impose a temporary settlement with limited concessions. It satisfied neither committed Catholics nor Protestants and provoked resistance.

Maurice of Saxony, who had aided Charles, turned against him. The princes’ revolt and French alliance forced the Peace of Passau in 1552. The episode shows why victory over an army could not reverse decades of territorial reform.

The Peace of Augsburg

Ferdinand negotiated the Religious Peace of Augsburg in 1555. It legally protected Catholicism and the religion of the Augsburg Confession within the imperial framework. Territorial rulers largely determined the public confession of their lands, while subjects who could not conform had a qualified right to migrate. Imperial cities received special arrangements.

The settlement was a breakthrough because it accepted that Lutheranism could not simply be outlawed out of existence. It was limited because it did not create individual religious freedom, excluded Reformed and Anabaptist Christians, and left disputed matters such as ecclesiastical territories. The later phrase cuius regio, eius religio is a useful summary, not wording that appears as the peace’s simple governing sentence.

Final course judgement

Luther was indispensable to the creation of Lutheranism, but he was not sufficient to explain its survival. His theology supplied purpose; print supplied reach; Melanchthon, pastors and teachers supplied organisation; princes supplied protection and government; imperial institutions supplied both conflict and negotiation; Charles’s wider wars supplied time. By 1555 religious division had become embedded in law because no actor could impose a single settlement across the Empire.

Check your understanding

1. Why did different princes support Lutheranism?
2. What did the Schmalkaldic League achieve, and what could it not do?
3. Why did Charles’s victory at Mühlberg fail to restore Catholic unity?
4. In what sense was Augsburg both a success and an incomplete peace?

The relationships to remember

Development	What it helped cause	Important qualification
Imperial political structure	Delayed uniform repression and enabled territorial reform	The emperor retained major authority and could win wars
Printing	Rapid spread, controversy and a recognisable movement	Oral teaching, protection and institutions remained necessary
Luther’s theology	A compelling challenge to Catholic authority and salvation teaching	Beliefs developed and were systematised with others, especially Melanchthon
Peasants’ War	Closer association between Lutheranism and political order	Rebellion had diverse social, economic, legal and religious causes
Princely support	Protection, church orders, schools and military alliance	Conviction and political interest cannot always be separated
Charles V’s foreign commitments	Time for Lutheran consolidation	They limited rather than eliminated imperial action
Mühlberg and the Interim	Demonstrated imperial military strength but political limits	Defeat of the League was not defeat of established Lutheran churches
Peace of Augsburg	Legal survival for Catholic and Lutheran territorial churches	It was not modern toleration and excluded other Protestants

How to answer the compulsory source question

The compulsory question asks you to assess how valuable two contemporary sources together are for a specified enquiry. It is worth 20 marks and assesses AO2.

For each source:

1. Identify its claims, tone and revealing details.
2. Use precise contextual knowledge to test and explain the content.
3. Evaluate provenance: author, audience, purpose, date and form.
4. Explain how those features increase or limit value for the exact enquiry.
5. Bring the two sources together in a reasoned overall judgement.

Do not treat value as a synonym for reliability. A hostile pamphlet may distort an opponent’s motives but be extremely valuable for studying propaganda, fears or attempted persuasion. Avoid detached provenance checklists: every comment must answer “valuable for what?”

Practice source enquiries

• The value of Luther’s writings for understanding his response to the Peasants’ War.
• The value of imperial documents for understanding Charles V’s policy.
• The value of princely statements for understanding support for Lutheranism.
• The value of confessional documents for understanding failed religious negotiations.

How to build the essay

The essay is worth 20 marks and assesses AO1. You choose one of two questions.

Turn the wording into criteria before writing. For a question asking whether princely support was the main reason for Lutheran survival, you could judge factors by whether they explain:

• Luther’s survival in 1521;
• the conversion of territories;
• the construction of durable churches;
• resistance to Charles V;
• legal recognition in 1555.

Build each paragraph around an argument:

1. Make a direct claim about the question.
2. Select precise evidence from across the stated dates.
3. Explain the causal relationship.
4. Test the factor’s limits or dependence on another factor.
5. Link back to your overall judgement.

Practice essay questions

1. How far did weaknesses in the German Catholic Church explain Luther’s success in the years 1517–21?
2. “Printing was the main reason why Luther’s challenge survived.” How far do you agree?
3. How significant was the Peasants’ War in changing the Lutheran movement?
4. How important was Melanchthon to the development of Lutheranism in the years 1521–46?
5. How far was princely self-interest responsible for the spread of Lutheranism?
6. “Charles V’s foreign commitments were the main reason for his failure to defeat Lutheranism.” How far do you agree?
7. How successful was the Peace of Augsburg in resolving religious division?
