Overview

In this epic deep-dive, Dan Snow brings to life the extraordinary story of William the Marshal, often dubbed "the greatest knight in the world" by contemporaries and posterity alike. Spanning the collapse and rise of empires, shifting allegiances, and the stormy Plantagenet dynasty, Marshal's life is charted from near-obscurity as a second son to the heights of power as regent and savior of the English realm. Using vivid retellings and direct quotations from contemporary sources and later biographies, Dan explores how one man's courage, loyalty, and political savvy shaped English – and European – history.

Key Discussion Points and Insights

1. Origins: Born in War and Turmoil (03:00–10:00)

• William the Marshal’s family roots: Born around 1146/7 to John FitzGilbert the Marshal and Sybilla, in the era of the Anarchy, a bitter civil war triggered by the death of King Henry I.
• A brutal childhood: At just five, William is given as a hostage during his father's siege at Newbury. In a legendary episode, his father refuses to surrender the castle, allegedly saying, “I still have the anvils and the hammers to produce even finer sons” (17:50), risking William's life—a testament to the ruthless times and the value placed on heirs.
• Anecdote of childhood resilience: William escapes royal wrath not through arms but by charming King Stephen: “Anyone who could ever allow him to die in such agony would certainly have a very cruel heart. He comes with such engaging, childish remarks.” (22:10)
• Feudal family politics: Dan details how shifting allegiances and violence were common as the backdrop to William’s early years, echoing the brutal flexibilities of medieval lordship.

2. Knighthood and the Tournament Circuit (23:30–36:00)

• Training in Normandy: Sent to his cousin’s (William de Tancarville) house as a customary apprenticeship, William learns the arts of war and the code of chivalry.
• Coming of age: Knighted in 1166, he immediately distinguishes himself in Normandy during border raids, but is left destitute when his patron downsizes his retinue. He chooses to strike out as a freelance knight rather than return to England in disgrace: “He had to sell his cloak, he bought a knackered old horse, ...he struck out across 12th-century Europe in search of adventure, money and fame.” (39:30)
• Rise through tournaments: William spins poverty into glory, capturing knights and accruing wealth, which propels him to continental fame.
• Memorable tournament feat: “He came out [of the tournament] with booty and money and the start of a reputation...tournament after tournament.” (41:30)

3. Service to the Plantagenets (45:00–1:05:00)

• First brush with royal power: William’s military prowess earns him a place in the retinue of the Earl of Salisbury, and subsequently in Queen Eleanor of Aquitaine’s circle after his uncle’s death in a Lusignan ambush. The episode details the violent and unpredictable nature of medieval power struggles.
• Tutor to the “Young King”: William is appointed tutor-in-arms to Henry the Young King, son of Henry II, becoming his loyal confidant, tournament partner, and ultimately a household name across Europe.
• Endless Plantagenet drama: Amid rebellions and internecine wars, William’s loyalty is tested as he sides with Young King Henry against Henry II, endures accusations of adultery, and faces exile.
• Remark on his loyalty: “When the French king welcomed young Henry, he provided a very sympathetic audience...Henry’s wife, Eleanor, joined them in Paris. In a flash, the entire edifice...came crashing down.” (59:00)

4. Crusading and Holy Land Sojourn (1:05:30–1:13:00)

• After Young King Henry’s death, William fulfills the young king’s crusader vow by journeying to Jerusalem. Though the historical record is sparse on details, Dan stresses the significance of this act—not only as a spiritual quest but as a move that burnishes William's status upon his return.
• “With Henry II’s blessing, William Marshal headed east...It was a deeply religious decision, but there were also chances of advancement.” (1:11:00)

5. The Height of Power under Henry II and Richard the Lionheart (1:15:00–1:35:00)

• Royal patronage and marriage: Henry II rewards William with an estate and a politically supercharged marriage to Isabel of Clare, heiress to vast lands in Wales and Ireland, making him a Marcher lord.
• Legendary duel: During the last desperate days of Henry II’s reign, William confronts Richard the Lionheart, sparing his life but killing his horse:
  • “God's leg, Marshal. Don't kill me. That would be a wicked thing to do, as you find me here completely unarmed.” (Richard, 1:31:30)
  • “Indeed. I won't let the devil kill you. I shall not be the one to do it.” (Marshal, 1:31:45)
• New era under Richard: William is forgiven by Richard, confirming the continuation of his lands and titles. Notably, loyalty—even to the beaten side—earns more trust from new kings than opportunistic switching.

6. The John Years: Trouble and Triumph (1:35:00–2:10:00)

• John’s reign—a catalogue of failure: Dan is candid: “He was cruel, incompetent, lecherous...literally the best thing he did for his country and his royal line was dying.” (1:57:00)
• Collapse of the Angevin Empire: John loses most French possessions; William briefly falls out of favor but is repeatedly called upon to resolve crises, both military and political.
• Baronial war and Magna Carta: William is central in negotiating Magna Carta, listed first among the barons in the preamble (2:03:30). Dan underscores that the Charter’s continued importance in English law is largely thanks to William reissuing it in 1216 and 1217.
• Faith amidst chaos: “If everyone abandons the boy but me, do you know what I shall do? I shall carry him on my back, and if I can hold him up, I will hop from island to island…” (2:16:40) — William’s pledge to young Henry III, highlighting his resolve and integrity.

7. Regency and Final Glory (2:15:00–2:28:00)

• William defends England as regent for young Henry III:
  • Battle of Lincoln (2:25:00): At age 70, William leads the decisive charge against Louis of France’s forces, turning the tide of invasion and ensuring the Plantagenet dynasty’s survival.
  • “At 70 years of age, mounted his muscle-bound destrier...and he bellowed, ‘Ride on.’ And he led the way through the gates.” (2:25:45)
• Naval victory at Sandwich (2:27:00): Orchestrates the crushing of the French fleet, forcing Louis to abandon his claim.
• Legacy cemented: William restores peace, reissues Magna Carta, and ensures leniency and reconciliation, securing the realm for good.

8. Death and Enduring Fame (2:28:00–2:31:00)

• William’s final months: He dies in May 1219 after being inducted as a Knight Templar.
  • “[Marshal] announced that he'd always intended to become a Knight Templar...‘I cannot fight against death,’” (2:30:10)
• Contemporary tribute: The Archbishop calls him “the greatest knight to be found in all the world.” (2:31:10)
• Tomb and monument: His effigy in Temple Church, London, survives to this day.

He had to sell his cloak, he bought a knackered old horse…like, well, Yoda and Luke Skywalker” – 39:30), sly humor, and a clear admiration for the subject’s resilience and virtue.
