Welcome to Medieval Britain: The Conquest of Wales and Scotland (up to 1314)

Hello! Welcome to your study notes on one of the most action-packed periods in medieval history. In this chapter, we will explore how King Edward I of England tried to bring the entire island of Britain under his single rule by invading Wales and Scotland.

We will look at famous battles, mighty stone castles, national heroes, and fierce rebellions. Don't worry if all the names and dates seem a bit overwhelming at first—we will break everything down step-by-step with helpful memory tips and clear explanations!

Key Concepts to Know First

Before diving into the invasions, let's understand two big ideas that drove these medieval wars:

1. Feudal Homage and Vassals: In the Middle Ages, kings believed in a strict hierarchy. If a ruler performed homage to another king, they knelt down, swore an oath of loyalty, and promised to be their vassal (a subordinate helper). English kings claimed that the rulers of Wales and Scotland were their vassals and owed them total obedience.

2. Overlordship: This meant having supreme authority over other rulers. King Edward I was determined to turn his theoretical claim of overlordship into real, direct political and military power over both Wales and Scotland.

Key Monarchs to Remember:
• King Edward I (reigned 1272–1307): Known as "Longshanks" because he was tall, and later nicknamed the "Hammer of the Scots". He was a brilliant military planner, ambitious, and ruthless.
• King Edward II (reigned 1307–1327): Son of Edward I. He lacked his father's military skill and faced major challenges, leading to disaster in Scotland.

Part 1: The Conquest of Wales (1277–1284)

In the 1200s, Wales was not a single unified country under English rule. Large parts of it were ruled by native Welsh princes, particularly in the mountainous north-west region called Gwynedd.

Why Did War Break Out?

In 1267, Llywelyn ap Gruffudd had been officially recognized as the Prince of Wales under the Treaty of Montgomery. However, when Edward I became King of England, Llywelyn refused to travel to England to pay feudal homage to him. Llywelyn also allied himself with Edward's political enemies (the Montfort family). Edward I viewed this as an act of open defiance and launched an invasion in 1277.

The First Welsh Campaign (1277)

Edward marched a massive army into Wales. His masterstroke was using a naval blockade to cut off the island of Anglesey, which was the main food supply (the "breadbasket") for the Welsh forces hiding in the mountains of Snowdonia. Starving and surrounded, Llywelyn was forced to sign the Treaty of Aberconwy (1277), which stripped away most of his land and power.

The Final War of Conquest (1282–1283)

English royal officials treated the Welsh people harshly, creating deep anger. In 1282, Llywelyn's brother, Dafydd ap Gruffudd, launched a surprise rebellion against English rule. Llywelyn joined his brother in the fight for Welsh independence.

• The Battle of Orewin Bridge (1282): Llywelyn the Last was killed in battle, leaving the Welsh resistance without their leader.
• The Fate of Dafydd (1283): Dafydd was hunted down, captured, and put on trial for treason. In 1283, he was executed by being hanged, drawn, and quartered. This was one of the earliest high-profile uses of this brutal punishment against someone accused of treason against the English Crown.

How Edward I Kept Control of Wales

Edward did not just defeat the Welsh armies; he completely rebuilt the political and physical landscape of Wales to ensure it could never break away again:

1. The Statute of Rhuddlan (1284): This legal act officially annexed Wales to the English Crown. It abolished native Welsh princely rule, introduced English common law, and divided the land into English-style administrative shires (such as Flint, Caernarfon, Anglesey, and Merioneth).

2. The "Iron Ring" of Castles: Edward spent colossal sums of money building state-of-the-art stone fortresses across North Wales. The most famous four are Caernarfon, Conwy, Harlech, and Beaumaris.

Why were these castles so effective?
• Concentric Design: They had rings of walls within walls, meaning attackers who breached the outer wall were trapped under fire from the taller inner wall.
• Supplied by Sea: Built along the coast, they could be resupplied by English ships even during a land siege.
• Colonies and Administration: They were not just military forts; they were attached to fortified towns for English settlers, acting as trade and administrative headquarters to govern the Welsh population.

3. The Title "Prince of Wales" (1301): To seal his victory, Edward I created his baby son, Edward of Caernarfon (who had been born in Wales and later became Edward II), the first English Prince of Wales in 1301. This started the royal tradition that continues today.

Quick Summary of Wales: By 1284, Edward I had conquered Wales through military force, naval power, the Statute of Rhuddlan, and the "Iron Ring" of castles. Native Welsh princely rule was brought to an end.

Part 2: The Scottish Campaigns up to 1314

Unlike Wales, Scotland had long been an independent kingdom with its own established line of kings. However, a sudden crisis in the royal family opened the door for Edward I to intervene.

1. The Succession Crisis: "The Great Cause" (1290–1292)

In 1286, King Alexander III of Scotland died, leaving his young granddaughter, Margaret (the "Maid of Norway"), as the sole heir. When Margaret died at sea in 1290, Scotland was left without an obvious monarch. Scottish nobles feared a bloody civil war between rival claimants (the two main rivals were John Balliol and Robert Bruce the Competitor).

The Scots invited King Edward I to act as an independent arbitrator (judge) to decide who had the best legal claim to the throne. Edward agreed, but demanded a heavy price: every claimant had to accept Edward as the feudal overlord of Scotland.

2. King John Balliol and the Outbreak of War (1292–1296)

Edward chose John Balliol to be King of Scots in 1292. However, Edward treated Balliol like a servant rather than an equal king, constantly humiliating him and demanding Scottish troops to fight in English wars.

Pushed too far, the Scots rebelled:
• The Auld Alliance (1295): Scotland signed a mutual defense treaty with France (England's greatest rival).
• The English Invasion (1296): Furious at this defiance, Edward I invaded Scotland, brutally sacked the town of Berwick, and forced Balliol to surrender his crown.
• Subjugating Scotland: Edward forced over 1,500 Scottish nobles and landowners to sign oaths of loyalty to him (collected in documents known as the Ragman Rolls). To show total conquest, Edward stole Scotland's sacred coronation stone, the Stone of Scone (Stone of Destiny), and took it to Westminster Abbey in London.

3. The Rebellion of William Wallace (1297–1305)

English occupation was harsh, sparking widespread resistance across Scotland led by a knight named William Wallace and his northern ally, Andrew de Moray.

• Battle of Stirling Bridge (September 1297): Wallace and Moray won a sensational victory against a vastly superior English army. They waited until the English vanguard began crossing a narrow wooden bridge, then charged down and trapped them, wiping out the crossing forces.
• Battle of Falkirk (July 1298): Edward I marched north to deal with Wallace personally. The Scots defended themselves in tightly packed hedgehog rings of spearmen called schiltrons. Edward used his devastating longbow archers to shower arrows down into the static schiltrons, breaking their ranks before sending in heavy cavalry to crush the Scottish army.
• Wallace's Capture (1305): Wallace escaped and spent years in hiding, but was betrayed and captured near Glasgow in 1305. He was taken to London, tried for treason, and executed by being hanged, drawn, and quartered.

4. Robert the Bruce Steps Forward (1306–1314)

The Scottish struggle did not end with Wallace. In 1306, Robert the Bruce (grandson of the Competitor) made his move:

• In 1306, Bruce murdered his chief Scottish rival, John Comyn, in a church in Dumfries.
• Bruce hurried to Scone and had himself crowned King Robert I (Robert the Bruce).
• When Edward I died on his way to Scotland in 1307, the English throne passed to his weaker son, Edward II.
• Bruce launched a brilliant guerrilla campaign over several years, recapturing English-held Scottish castles one by one.

5. The Battle of Bannockburn (23–24 June 1314)

By 1314, only one major Scottish fortress remained in English hands: Stirling Castle. The English garrison promised that if a relief army did not arrive by midsummer, they would surrender.

King Edward II marched a massive, well-equipped English army north to save Stirling. Robert the Bruce intercepted them nearby at the Battle of Bannockburn.

How Did the Scots Win?
• Terrain: Bruce chose ground hemmed in between thick woods, the Bannock Burn (a stream), and the tidal marshes of the River Forth. The English army was packed into a cramped area where their superior numbers were useless.
• Mobile Schiltrons: Unlike at Falkirk, the Scottish spearmen moved forward in disciplined, mobile schiltrons, pushing the English back into the muddy water.
• The Outcome: The English lines broke in total panic. King Edward II fled the battlefield to save his life.
• Significance: Bannockburn was a decisive Scottish victory. It shattered English military control and secured de facto (actual) independence for Scotland.

Common Historical Pitfalls & Misconceptions

Make sure you do not lose marks by falling into these common traps in your work!

Mistake 1: Thinking all Welsh or Scottish people were united against England.
Fact: Neither Wales nor Scotland was completely united. Welsh princes frequently fought each other, and Edward I used rival Welsh troops in his campaigns. In Scotland, powerful noble factions (such as the Bruces and the Comyns) fought brutal internal feuds, and many Scottish lords allied with Edward at different points.

Mistake 2: Thinking Edward I conquered Scotland permanently.
Fact: Edward I successfully conquered and annexed Wales (via the Statute of Rhuddlan in 1284). However, his attempt to conquer Scotland ultimately failed, ending with English defeat at Bannockburn in 1314.

Mistake 3: Thinking Edward I fought at the Battle of Bannockburn.
Fact: Edward I died in 1307. It was his son, Edward II, who commanded and lost the battle in 1314.

Mistake 4: Thinking Edward's castles were just defensive military bases.
Fact: The "Iron Ring" castles were also royal administrative hubs, symbols of English dominance, and economic colonies designed to settle English merchants in Wales.
