Timeline of Owen Glendower:

1386: Glendower becomes Squire to the Earl of Arundel and is a witness for Grosvenor in the Scrope and Grosvenor lawsuit. Afterwards Glendower serves in the military forces of Henry Bolingbroke (Later King Henry the Fourth).

1400: Owen Glendower is charged with treason by Reginald Grey for failing to appear for the Scottish Expedition even though he had never summoned him. His estates are declared forfeit.

1401: He quarrels with Lord Grey over the rights to some lands and unable to seek redress from the English King Henry the Fourth he decides to fight the other English Lords of the Welsh Marches borderlands. He proclaims himself the Prince of Wales and head of the Welsh Rebellion.

1402: Glendower captures Lord Grey and later Sir Edmund Mortimer at Pilleth, near Brynglas in Radnorshire, Wales. Both were to marry one of Glendower’s daughters and join in a coalition with Henry Percy (known as Hotspur) against the English. In the Autumn the English are driven back from Wales for the third time.

1403: This coalition is ended when Glendower is defeated near Carmarthen on the 12th July and Percy crushed at the Battle of Shrewsbury ten days later by King Henry the Fourth. Undaunted Glendower holds a Welsh parliament at Machynleth.

1404: By now Glendower had gained overall control of Wales. He enters into a treaty with King Charles the Sixth of France. He also takes control of the castles at Harlech and Aberystwyth.

1408: Henry captures Owen Glendower’s strongholds of Aberystwyth after a long siege. The plots of the Earl of Northumberland and the French armies had come to nothing and this was effectively the end of the armed struggle.

1409: Harlech is also recaptured and Glendower’s wife, daughter and grandchildren are taken prisoner.

1409-1412: However undeterred, Glendower is still active and keeps on fighting against the English but the force of the rebellion by then was effectively crushed.
