Henry IV King of England

Born in 1367, Henry forced Richard II to abdicate in 1399 and then was crowned shortly afterwards. He was the first Lancastrian king. He died in 1413.

To get the big picture, let’s start with genealogical tables from credentialed Medievalists.


Henry IV begins the later Plantagenets, who will soon divide into the Houses of Lancaster and York (see the post about Henry VI). They will struggle for the throne in what will later be called the Wars of the Roses. The White Rose will come to symbolize the Yorkists, while the Red Rose the Lancastrians.

Did Henry and the Lancastrians have the best claim to the throne? Not really. The Yorkists descend from Lionel, the older brother to John of Gaunt, and from yet another son of Edward III, Edmund of Langley, duke of York. In an age of hereditary laws and beliefs, it rankled the Yorkists that Henry’s line became monarchs, just because he usurped the throne.

Children of Henry IV and Mary:

0. Unnamed child, born about 16 Apr 1382, who died in infancy. However, Anne Curry, in her biography Henry V, says this son did not exist, but was based on a misreading of a financial record (p. 3). So Henry, next, is the firstborn.

1. Henry will become Henry V. For the basics, he was born at Monmouth 16 Sep 1386 (or 1387). Shakespeare named him Prince Hal. He succeeded his father 21 Mar 1412 and was crowned king on 9 Apr 1413.

They had three sons: Edmund (ancestor of future Henry VII), Jasper, and Edward (Benedictine monk). She died at Bermondsey Abbey, Surrey, 3 Jan 1437 and was at first buried in the Lady Capel in Westminster Abbey. Her coffin was then moved to Henry V’s chantry in Westminster Abbey. Owen was placed under arrest and sent to Newgate prison from which he escaped in July 1439. He received a royal pardon “for all offences” on 12 Nov 1439. In 1459 he received an annuity of £00 for life by Henry VI.

Illegitimate child of Henry and unknown mistress:

7. Edmund le Boorde, clerk, born about 1401 (aged 11 in 1412). He took holy orders. He died shortly before 19 Dec 1419.


  1. His name Bolingbroke (Bolingbrook) came from his birthplace.
  2. He did not have the strongest claim to the throne when he overthrew his cousin Richard II in 1399.
  3. Richard descended from Edward III’s eldest son, while Henry was the son of Edward’s third surviving son, John of Gaunt. The throne should have gone to seven-year-old Edmund Mortimer, son of Edward’s second surviving son, Lionel of Antwerp.
  4. However, Henry was the better man for the job than young Mortimer.
  5. Richard and Henry were about the same age and as boys played together.
  6. As Henry grew, he became a champion jouster and demonstrated his piety by going on a crusade in Eastern Europe.
  7. In the early years Richard’s government was in the hands of Henry’s father, John of Gaunt. When he left for Spain in 1386, Henry joined the Lords Appellant, Richard’s opposition.
  8. John of Gaunt returned, and Richard forgave Henry by making him duke of Hereford.
  9. Henry crusaded against pagans of Lithuania (1380) and Prussia (1392). He went on a pilgrimage to Jerusalem in 1393.
  10. Richard II created an atmosphere of fear by executing and exiling many barons. One illustration of this took place when Henry made an offhand remark about Richard’s rule to Thomas Mowbray, duke of Norfolk and once his fellow-Lords Appellant.
  11. Holy Mary, cousin! What is our cousin the king up to? There will soon be nobody left. He shows quite clearly that he does not want to advance the fortunes of the kingdom.”
  12. Norfolk accused Henry in the king’s hearing of treason.
  13. Richard II ordered them to battle it out in combat, but at the last moment the king stopped it and instead exiled them
  14. In Henry’s absence, his father John of Gaunt died in 1399. Richard II showed his rigid and heartless rule when he confiscated all of John’s estate that Henry was to inherit from his father as duke of Lancaster.
  15. While Richard was away on campaign against Ireland, Henry returned to England. Did Henry just want to recover his land, or did he intend to become king?
  16. He received much popular support from England, which must have convinced him to go all the way to kingship.
  17. He succeeded on 30 Sept 1399, when Henry forced Richard’s abdication, and parliament confirmed Henry’s claim to the throne.
  18. Richard was detained in Pontefract Castle in Yorkshire, where he died a year later, possibly on Henry’s orders.
  19. Henry was crowned on 13 Oct 1399. He made his address in English, rather than French, the first time since the Norman conquest in 1066.
  20. Henry knew how to compromise with parliament and was an effective administrator of the realm, though he brought debt on the country.
  21. However, just because he was effective does not mean no one opposed him. Richard II’s allies still roamed the land. What about Edmund Mortimer?
  22. Also Owen Glendower, a wealthy landowner in Denbighshire in northeast Wales, may have sensed weakness. He rallied his countrymen and revolted against English rule.
  23. On 16 Sep 1400 Owen declared himself Prince of Wales. By 1405 he liberated the country against England, despite Henry’s series of campaign against him.
  24. In 1401 he arranged the marriage of his daughter to Edmund Mortimer, earl of March, who had been Richard II’s heir apparent before Henry’s coup.
  25. In 1403 Henry Percy, earl of Northumberland, turned against Henry and supported Edmund Mortimer.
  26. Scotland and France supported Edmund, but Scotland was defeated at Homildon Hill in Northumberland in 1402, France sent a force that landed in Wales in 1405-06.
  27. On 21 July 1403 Glendower suffered defeat at Shrewsbury, along with Archibald, earl of Douglas, and Percy’s son, Sir Henry Percy (“Hotspur”). Prince Henry (future Henry V) fought bravely and took an arrow to the face.
  28. Percy was slain. It was said that Henry wept over the corpse, but displayed it anyway instead of burying it properly.
  29. Contrary to Shakespeare’s play, Henry IV Part II, “Prince Hal” did not kill him.
  30. In 1405 King Henry’s old adversary Thomas Mowbray, duke of Norfolk, and Richard Scrope, Archbishop of York, joined Glendower, Mortimer, and Northumberland in rebellion. They agreed to divide England between them.
  31. Mowbray and Scrope were lured to a meeting with Henry and were arrested and immediately executed. Percy escaped to Scotland. Henry received widespread criticism for executing the archbishop.
  32. The Long Parliament met in Mar 1406 and sat for 130 days. They complained that the king was squandering his money and failing to protect the sea routs to Gascony, in southwest France (trade) and the English south coast.
  33. At the Long Parliament the Commons compelled Henry to accept thirty-one articles that required him to take steps to improve. Example: He had to meet with his council that the Commons purged of people they did not like.
  34. In other words, Henry IV did not win widespread loyalty across the land, for people knew he was a usurper.
  35. Percy returned at the head of an army, but was killed at Branham Moor, Yorkshire, on 19 Feb 1408.
  36. Since King Henry had usurped the throne on a tenuous claim and had to fight a succession of rebellions, he had to compromise with parliament on royal expenditures and appointments. He did so out of pragmatism, but maintained a lot of royal power. He left the country in heavy debt, however.
  37. Glendower’s rebellion fizzled, and he himself disappeared.
  38. All the rebellions broke Henry’s health. Prince Henry (later Henry V) took effective power in 1410.
  39. In 1411 recovering his health a little, King Henry reasserted his authority, but he had a skin disease that some said was leprosy, but it probably came from syphilis. He suffered a series of attacks, probably strokes. Many believed it was God’s vengeance for killing the archbishop.
  40. During Henry’s declining health, a power struggle broke out in court in two factions: (1) the King and Thomas Arundel, archbishop of Canterbury and (2) Prince Henry and Thomas and Henry Beaufort, two sons of John of Gaunt. Prince Henry’s side won, but without complete success.
  41. Shakespeare dramatized the struggle by placing the king’s crown next to him in bed. The prince took the crown and placed it on his own head. Prince Henry had to wait until his father died before the younger took charge.
  42. It had been prophesied that Henry would die in Jerusalem, but the capital of Israel? No, there was a chamber at Westminster called the Jerusalem Chamber, where he actually died on 20 Mar 1413.
