Key Idea: A medieval war is never just a battle — it sends ripples through power, land, money and people for decades. This topic gives you one framework for sorting any war's effects, then two case studies to prove it works. The golden thread across all three micros: wars that look like military defeats can still cause huge lasting change. The Crusades lost every inch of land yet reshaped Europe's economy and religion; the Hundred Years' War wrecked France on the ground yet built the strong French state. Paper 2 rewards you for spotting that gap between what happened on the battlefield and what mattered in the long run.
Everything in 7.3 hangs off one habit: don't retell the war blow by blow — sort its effects into categories and then argue which mattered most. The framework from 7.3.1 is your toolkit. The Crusades (7.3.2) and the Hundred Years' War (7.3.3) are the two wars you feed into it. Learn the framework first, then hang the facts on it.
The six-drawer framework (7.3.1)
- Political & dynastic — who rules, which {{dynasty|a line of rulers from the same family}} rises or falls, and the balance of power between states
- Territorial — land won, lost or swapped, and borders redrawn
- Growth of the state — war forces kings to raise {{taxation|money the crown collects from its people}}, expand officials and keep {{standing forces|paid soldiers kept permanently, not just in wartime}}, so the crown grows stronger
- Social & economic — disrupted trade and farming, revolts over war taxes, and deeper shifts in how society is organised
- Human cost — deaths, {{displacement|people forced to flee their homes}}, famine and destroyed communities
- Peace settlements — the treaties that end the fighting, and whether they actually last
Political · Territorial · Growth of the state · Social-economic · Human cost · Peace settlement. Six drawers. Before you write, run down the list and check you've filed something in each one — an empty drawer is a lost mark. The single most-missed drawer is growth of the state: war is expensive, so kings squeeze more tax and keep more soldiers, and those wartime tools become permanent.
Covering all six drawers gets you a solid mid-band essay. To reach the top band you must weigh them — argue which category mattered most and why, split short-term effects from long-term ones, and reach a clear judgement backed by dates and names.
Case study 1 — the Crusades (7.3.2)
Launched in 1095 by Pope Urban II to win back the Holy Land, the Crusades succeeded at first — Jerusalem fell in 1099 and Christian Crusader States rose along the {{Levant|the eastern Mediterranean coast — today Israel, Lebanon and Syria}}. But by 1291 every inch was gone. The lesson: the wars failed on the ground yet transformed the world off it. That paradox is your whole thesis.
- 1099 — Jerusalem captured (with a massacre of Muslims and Jews); Crusader States founded
- 1187 — Saladin wins at Hattin and retakes Jerusalem
- 1204 — the Fourth Crusade sacks Christian Constantinople, crippling Byzantium
- 1291 — fall of Acre: Crusaders expelled from the Levant for good
- 1453 — long-weakened Byzantium finally falls to the Ottomans
Economic — the trade boom (the effect that lasted) Supplying the Crusader States meant huge Mediterranean shipping. The Italian city-states — Venice, Genoa and Pisa — ran it and grew immensely rich. Europeans developed a taste for eastern spices, silk and sugar, and Italy controlled the routes, wealth that later helped fund the Renaissance.
Religious & cultural — cuts both ways The dark side: Christian–Muslim hostility hardened, and Crusaders massacred Jewish communities in the Rhineland (1096) and at Jerusalem (1099), poisoning relations for centuries. The other side: eastern medicine, mathematics, foods and Arabic-preserved Greek texts flowed into Europe.
Political — papacy up, Byzantium down Calling and blessing the Crusades let the Pope command all of Christendom, boosting papal prestige. But Byzantium, which had asked the West for help, was fatally weakened — the Fourth Crusade sacked its capital in 1204, and it never truly recovered before 1453.
Example: When the Crusaders stormed Jerusalem in July 1099 they massacred much of the city's Muslim and Jewish population; chroniclers on both sides wrote of streets running with blood. It wasn't a one-off — two centuries of Crusading brought death by battle, disease and starvation. Never leave the human cost out: it's the drawer that keeps your essay from feeling bloodless.
Case study 2 — the Hundred Years' War (7.3.3)
Not one war but a run of wars over 116 years (1337–1453), begun when England's Edward III claimed the French throne. The killer point: the same war pulled the two kingdoms in opposite directions. France came out stronger and more united; England came out defeated, indebted and sliding toward civil war. Compare the two sides throughout and you're already arguing like a top-band candidate.
France — the war strengthened it: Reunited kingdom; England driven out except Calais by 1453. Permanent taxes (the taille) gave the crown a steady income. First standing army created by Charles VII in 1445. Royal power rose over the nobles — the war built the French state. A new national pride, symbolised by Joan of Arc.
England — the war weakened it: Lost almost all its French lands, keeping only Calais. Crushing war debt and wasted spending. A discredited king in Henry VI and idle noble armies. Slid into the Wars of the Roses (1455–1487). Bitterness and blame poisoned politics at home.
Example: In 1429 the peasant girl {{Joan of Arc|French heroine who rallied France in 1429; executed 1431}} claimed God had sent her to save France. She helped lift the siege of Orléans and had Charles VII crowned at Reims. Captured and burned by the English in 1431, she became a lasting symbol of French resistance — the perfect evidence for the war's effect on national identity.
Important: Both great peace deals collapsed, and saying why lifts an essay. Brétigny (1360) gave Edward III a huge independent Gascony but fell apart within a decade. Troyes (1420) made Henry V heir to France but died with him in 1422 and was overturned by Joan of Arc's revival. The rule: each treaty reflected only one side's temporary high point, so the loser refused to accept terms it had signed under pressure. No settlement held because neither side truly accepted defeat.
Fast facts across the topic
| Drawer | Crusades | Hundred Years' War |
|---|---|---|
| Territorial | States founded 1099, all lost by 1291 (Acre) | England reduced to Calais by 1453 |
| Growth of the state | (Not the focus — papacy's authority rises instead) | France: permanent taxes + first standing army (1445) |
| Political / dynastic | Papacy strengthened; Byzantium fatally weakened | France unified; England falls into the Wars of the Roses |
| Social / economic | Mediterranean trade booms; Italy grows rich | French countryside looted and devastated; heavy taxation |
| Human cost | Massacres (Jerusalem 1099); huge casualties | French villages burned and starved by roaming soldiers |
| Peace settlement | No lasting settlement — states simply overrun | Brétigny (1360) and Troyes (1420) both collapsed |
Both wars teach the same big idea from a different angle. The Crusades show a war that lost its land yet changed the world through economics, religion and papal power. The Hundred Years' War shows a war that reshaped kings and states — building one country up while tearing another down. Put them side by side and you can answer almost any 'effects of a medieval war' question.
Compare and contrast the effects of two medieval wars, each from a different region.

Three things separate a top-band 7.3 answer from a mid-band one: 1. Sort, don't narrate. Group your paragraphs by the six drawers, never by chronology of battles. 2. Weigh and judge. Argue which effect mattered most and split short-term from long-term — the Crusades' paradox (failed militarily, huge long-term impact) and the Hundred Years' War's contrast (France up, England down) are your two killer lines. 3. Anchor every claim with a date or name. 1099, 1204, 1291, 1337, 1360, 1420, 1445, 1453; Saladin, Joan of Arc, Charles VII, Henry VI. Precise evidence is what turns a fair argument into a top-band one.
