The Plantagenets & the Hundred Years' War

UK History

Chapter 5 · The Plantagenets & the Hundred Years' War

Chapter 4 covered the Norman conquest. This chapter follows the dynasty that ruled England from 1154, the Plantagenets, and the long war with France that dominated much of the fourteenth and fifteenth centuries. The sources are two reference articles, one on the dynasty and one on the war. They give dates and outcomes but little on how ordinary people experienced either, and the chapter marks what they leave out.

The Plantagenet Dynasty

The House of Plantagenet ruled England from 1154 to 1485. Henry II began the dynasty, and Richard III's death at the Battle of Bosworth Field ended it.

ReignKingWhat the source says
1154 to 1189Henry IIEstablished extensive continental territories.
1189 to 1199Richard ITook part in the Crusades.
1199 to 1216JohnLost most French holdings, including Normandy, by 1204.
Only Some Kings Appear The source I used names these three kings and Edward I and Edward III; it does not list the others. I did not research Henry III, Edward II or Richard II, so the chapter does not describe their reigns. Whether the dynasty is properly called "Plantagenet" for its whole span is a naming question I did not look into.

Law and Parliament

The source describes the period as one in which "the king was no longer just the most powerful man in the nation" but acquired "defined duties to the realm, underpinned by a sophisticated justice system." It names two key developments: Magna Carta in 1215, and Simon de Montfort's Great Parliament of 1265, which first included city and borough representatives.

Where to Read More UK Politics Fundamentals 1 covers Magna Carta and the sources of the constitution in detail. This chapter mentions it only as part of the dynasty's story and does not repeat that account.

Expansion Within the Isles

Edward I conquered Wales and asserted claims over Scotland, and established the first English Prince of Wales. Edward III saw the adoption of Middle English in governance. I did not find the dates of these events or how the Scottish claim ended.

The Hundred Years' War

The conflict spanned 1337 to 1453, about 116 years, intermittently. Historians divide it into three phases:

The Edwardian War

1337 to 1360.

The Caroline War

1369 to 1389.

The Lancastrian War

1415 to 1453.

Why It Began

The war emerged from feudal disputes over the Duchy of Aquitaine. It was triggered when Edward III claimed the French throne after Charles IV died in 1328 without male heirs. The French nobility rejected his claim on the basis of Salic law and chose Philip VI instead.

Two Levels of Cause The source gives a long-term cause, the dispute over Aquitaine, and a triggering one, the succession claim. It does not weigh them or explain why the war began in 1337 and not in 1328. I did not find that.

The Main Events

YearEvent
1346Battle of Crécy: a decisive English victory.
1356Battle of Poitiers: the English capture King John II.
1415Battle of Agincourt: Henry V's overwhelming victory.
1420Treaty of Troyes: recognizes Henry V as French heir.
1429Siege of Orléans: Joan of Arc inspires a French revival.
1453Battle of Castillon: the final English defeat.

Consequences

  • The war transformed European warfare, through professional standing armies and artillery.
  • It strengthened national identities in both kingdoms.
  • England lost its continental possessions except Calais, which it held until 1558.
  • The loss contributed to the domestic instability that led to the Wars of the Roses (Chapter 6).
Two Endings in One Chapter The Plantagenet dynasty is dated to 1485 and the war to 1453. The gap of thirty-two years contains the Wars of the Roses, which the source presents as a fight between the York and Lancaster branches of the same family, ended when Henry VII defeated Richard III and married Elizabeth of York. Chapter 6 takes that up.
What I Did Not Verify I did not find the Black Death, the longbow's role, the war's cost and taxation, the peasants' experience, or the effect on the English language, which the outline anticipated. I also did not check the claim that England held Calais until 1558 against another source.

Hands-On Exercises

Exercise 1

Set out the three phases of the Hundred Years' War with their dates and name one event from the third phase.

Exercise 2

A student writes "The Hundred Years' War lasted exactly 100 years." Use the chapter to correct it.

Exercise 3

Explain the difference between the war's long-term cause and its trigger, and name one thing the sources do not explain.
