IB History (2028+) HL — Medieval kingdoms and empires (c.750-1400)

Topic 13.1 of IB History (first exams 2028) covers Medieval kingdoms and empires (c.750-1400), which is part of Unit 13: Paper 3 · History of Europe (HL). Students explore key concepts including Medieval kingdoms — emergence and authority, Medieval kingdoms — religion, culture and society, Medieval kingdoms — decline and a key leader. A strong understanding of medieval kingdoms and empires (c.750-1400) is essential for IB History (2028+) HL exams and builds the foundation for connected topics across the syllabus.

Higher Level students should use this topic hub as a map: start with the shared sub-topics, then follow the HL-only extensions and exam-skill links where this topic asks for deeper analysis.

Key concepts in Medieval kingdoms and empires (c.750-1400)

Key Idea: Between about 750 and 1400, kingdoms in Europe were built, made to look rightful, held together day-to-day, and — eventually — pulled apart. This topic follows that whole life cycle through one central case study, Charlemagne's Carolingian Empire, plus comparisons like Norman England and Capetian France. Religion runs through every stage: it crowned kings, ran daily life, and could just as easily undermine a ruler as support one.

How this topic is tested

You answer two essays from this regional option, each worth 15 marks. The command term is always some version of 'To what extent do you agree...' or 'Evaluate the claim that...' The skill being tested is NOT how many facts you can list — it is whether you can take a clear position, argue both sides with named evidence (rulers, dates, events), and reach a substantiated judgement. You do not need historiography or named historians to reach the top mark band — specific, accurate evidence is what matters most.

Must-know facts from every sub-topic

This topic has three micro-topics. Together they cover why kingdoms rose, how religion shaped politics and society, and why kingdoms eventually fell apart.

Micro-topicWhat it coversKey names & dates
13.1.1 Emergence, legitimization, consolidationKingdoms grew from economic strength, dynastic marriage/inheritance, shared religion/culture, and conquest. Rulers then legitimized power through coronation, law and written records, and consolidated it day-to-day through nobility, taxation, and force held in reserve.Charlemagne (r.768-814): conquered Lombards 774, Saxons 772-804, crowned Emperor by Pope Leo III, Christmas 800. William I (r.1066-87): won Hastings 1066, ordered Domesday Book 1086. Philip II Augustus (r.1180-1223): seized Normandy from King John 1202-04 using feudal law. Magna Carta 1215 — barons force King John to limit royal power.
13.1.2 Religion, institutions, culture and societyReligion legitimized rulers (coronation, divine right, excommunication, interdict) and ran everyday life through parishes, monasteries, canon law courts and universities. The papacy peaked under Innocent III, then weakened (Avignon Papacy, Great Schism). Technology and Gothic culture flourished alongside deep inequality.Investiture Controversy 1076-1122 (Henry IV at Canossa, 1077). Innocent III 1198-1216 (King John submits, 1213; Fourth Lateran Council, 1215). Avignon Papacy 1309-1377. Great Schism 1378-1417. Scholasticism — Thomas Aquinas. Jews expelled from England, 1290. Albigensian Crusade against the Cathars from 1209.
13.1.3 Decline of kingdoms + Charlemagne case studyKingdoms declined through four interacting causes: internal rebellion, economic/social strain, political rivalry/succession disputes, and external attack. Charlemagne's empire shows the full cycle — conquest and coronation, consolidation tools, cultural revival, then rapid collapse after his death.Charlemagne sole king 771; crowned Emperor 800. Tools of control: counts, missi dominici, capitularies. Carolingian Renaissance led by Alcuin at Aachen. Charlemagne dies 814; Louis the Pious's sons fight a civil war. Treaty of Verdun 843 splits the empire into three. Viking raids intensify from the 840s (sack of Paris, 845).
  • Legitimization — making power look rightful through coronation, law, and records, not just conquest.
  • Feudalism — land granted in exchange for loyalty and military service; the glue (and occasional weak point) holding noble support together.
  • Partible inheritance — splitting a kingdom between heirs, as Frankish custom did in 843; it automatically weakens central power.
  • Excommunication / interdict — the papacy's weapons against disobedient rulers, expelling a king from the Church or suspending sacraments across his whole kingdom.
  • Missi dominici — Charlemagne's paired inspectors (a noble and a bishop) who toured the empire checking that local counts stayed loyal.

Modelled exam question

IB-style questionTo what extent do you agree[15 marks]

To what extent do you agree that internal weaknesses were more important than external threats in causing the decline of the Carolingian Empire?

Important: Writing a 'to what extent' essay as a simple list of facts with no position. Every paragraph must connect back to the claim in the question — say whether that evidence supports or challenges it, and end with a clear, defended judgement, not just a summary of events.

What four factors explain the rise of medieval kingdoms? Economic factors (control of farmland and trade), political/dynastic factors (marriage and inheritance), social/cultural factors (shared religion), and conflict/conquest — and they usually worked together, not alone.

How did William I legitimize his rule after 1066? He was crowned by the Archbishop of York on Christmas Day 1066 and later commissioned the Domesday Book (1086) to record and prove control over his new kingdom, turning a military conquest into settled, documented rule.

What was the Investiture Controversy and why does it matter? A struggle (1076-1122) between Pope Gregory VII and Emperor Henry IV over who could appoint bishops. Henry was excommunicated and stood barefoot in the snow at Canossa (1077) seeking forgiveness — proof that religious authority could directly threaten a ruler's political power.

Name two ways the papacy's power was later weakened. The Avignon Papacy (1309-1377), when the French crown effectively controlled the pope, and the Great Schism (1378-1417), when rival popes split the Church's authority.

What four causes explain the decline of medieval kingdoms? Internal rebellion, economic and social strain, political rivalry and succession disputes, and external threats — and they typically fed each other rather than acting alone.

How did the Carolingian Empire actually collapse after Charlemagne? Charlemagne died in 814; his son Louis the Pious's sons fought a succession war in the 830s-840s; the Treaty of Verdun (843) split the empire into three kingdoms; and Viking raids from the 840s (e.g. the 845 sack of Paris) exploited the resulting division.

Always name a specific kingdom or empire (Carolingian, Norman/Angevin England, Capetian France, the papacy) with real dates — never write about 'medieval Europe' in the abstract. Link your causes together: show how economic strain fed rebellion, how rebellion invited succession disputes, and how disputes let external raiders in. And always finish with a direct answer to 'to what extent' — a clear degree of agreement, not a list of facts.
