What happened

In September 1400 Owain Glyndŵr, a Welsh landowner descended from the princes of Powys and Deheubarth, was proclaimed Prince of Wales by his kinsmen after a land dispute with his neighbour Reginald Grey, lord of Ruthin, and his followers attacked Ruthin and other English-held towns in north-east Wales. In 1401 his cousins took Conwy Castle. In 1402 his forces defeated and captured Sir Edmund Mortimer at Bryn Glas; Mortimer then joined Owain and married his daughter. Owain's English allies, the Percys, were defeated at Shrewsbury in 1403. In 1404 he took Harlech and Aberystwyth, held an assembly at Machynlleth and made a treaty with Charles VI of France, whose troops landed at Milford Haven in 1405. From 1405 his forces lost ground: English armies under Henry of Monmouth blockaded Wales and took Aberystwyth in 1408 and Harlech in 1409. Owain fought on from the hills, was last seen by his enemies in 1412 and was never captured. No reliable count of the dead survives.

Outcome: The English crown again held all of Wales between 1409 and about 1415; Owain disappeared around 1415, and his son Maredudd accepted a royal pardon in 1421.
