Medieval kingdoms and empires (c.750-1400)

A system where a king grants land (a fief) to nobles in exchange for military service and loyalty.

Economic (control of farmland/trade routes), political/dynastic (marriage alliances, inheritance, conquest), and social/cultural (a shared religion and language binding a kingdom together).

Through decades of warfare — conquering the Lombards in Italy (774), the Saxons (772–804), and campaigns against the Avars — then being crowned Holy Roman Emperor by Pope Leo III in 800.

By claiming Edward the Confessor had promised him the throne, having himself crowned by Ealdred, Archbishop of York, on Christmas Day 1066, and commissioning the Domesday Book (1086) to record and control his new kingdom's wealth.

It legitimized a king's rule by publicly tying his power to promises of just and lawful government, often blessed by the Church.

Taxation — for example scutage (a cash payment nobles could pay instead of military service) gave kings steady income and reduced dependence on unreliable nobles.

Nobles enforced the king's law locally, supplied knights for his armies, and sat on his council — but they could also rebel if they felt sidelined, so kings had to balance reward and control.

He seized most of the Angevin lands in France (including Normandy, 1204) from King John of England and built a stronger royal bureaucracy of paid officials (baillis) to administer conquered territory directly.

1) Issue law codes/charters in the king's name. 2) Set up royal courts so the king (not local lords) delivers justice. 3) Present the king as guardian of order under God, making obedience seem natural and right.

Legitimization is convincing people your rule is rightful (coronation, religion, law); consolidation is making that rule actually work day-to-day (officials, taxes, castles, force).

Force can win territory and punish rebels quickly, but permanent rule needed cooperation from nobles and the Church — armies were expensive and rebellions kept recurring if legitimacy was never built.

Writs let kings like the Norman/Angevin rulers of England issue direct, enforceable commands, extending royal authority into everyday local disputes.

The idea that a monarch's power comes directly from God, not from the people — so to disobey the king is to disobey God himself.

Pope Leo III crowned Charlemagne 'Emperor of the Romans' in Rome. It set a precedent that the Church could make — and by implication unmake — emperors.

A power struggle between the papacy and Holy Roman Emperors over who could appoint bishops. It showed the Church actively contesting, not just legitimizing, royal power.

Excommunication is formal expulsion from the Church, cutting a person off from the sacraments. For a medieval king it could mean nobles were released from their oath of loyalty, so it was a real political weapon.

It ran nearly all schools and universities, operated hospitals and poor relief, and (through canon law courts) judged marriage, wills, and moral offences.

A method of reasoning that used logic to reconcile Christian faith with classical philosophy (especially Aristotle). Thomas Aquinas is the most famous scholastic thinker.

The heavy plough and three-field crop rotation raised farm yields and fed growing towns; the mechanical clock and eyeglasses (13th century) changed how people measured time and read.

A building style (pointed arches, ribbed vaults, flying buttresses, huge stained-glass windows) used for cathedrals like Chartres and Notre-Dame. It shows enormous wealth, skill, and religious devotion channelled into public building projects.

Convents let abbesses run large institutions, control land, and educate; figures like Hildegard of Bingen wrote theology, music, and even advised bishops and popes.

A heretical Christian sect in southern France whose beliefs rejected Church authority; the Albigensian Crusade (from 1209) shows the Church using violence to enforce religious conformity and treat dissenters as a marginalized group.

Often tolerated for their role in trade and moneylending but periodically scapegoated, taxed heavily, forced into ghettos, or expelled (e.g. England 1290), showing the limits of the Church's protection.

Whether the papacy's authority was mostly genuine and effective (Innocent III's peak) or mostly symbolic/contested, since kings frequently defied, taxed, or imprisoned popes (e.g. Avignon Papacy from 1309).

Internal challenges (rebellion); economic and social challenges; political challenges (rivalries and succession); external threats.

A custom of dividing a ruler's land and titles among multiple heirs, rather than passing the whole kingdom to one person.

Charlemagne's grandsons rebelled and fought a civil war over the Carolingian inheritance after Louis the Pious's reign.

Poor harvests or heavy taxation caused popular anger, which rebel nobles could exploit to build support against the crown.

Internal causes (rebellion, succession disputes) came from within the kingdom; external causes (raids, invasions) came from outside — but external attacks usually succeeded because internal causes had already weakened the kingdom.

Christmas Day, 800 AD, by Pope Leo III in Rome.

Royal inspectors (usually a noble and a bishop) sent by Charlemagne to check that local counts governed loyally.

A revival of learning, art, and Latin literacy at Charlemagne's court, led by scholars such as Alcuin, that preserved classical and Christian texts.

He forced the conquered Saxons to convert to Christianity or face death, enforcing religious unity across the empire.

Charlemagne dies (814) → Louis the Pious struggles to control the empire → his sons fight a succession war → Treaty of Verdun (843) splits the empire into three → Viking raids exploit the divided kingdoms.

In expansion, Charlemagne's conquests and coronation built a vast, unified empire; in decline, the succession custom he did not reform (partible inheritance) caused that same empire to fracture after his death.

Counts to govern local districts, missi dominici to inspect them, capitularies (royal decrees) to set unified law, and personal oaths of loyalty from nobles.
