The title Duke of Exeter was created several times in England in the later Middle Ages. Exeter is the main town of Devon. It was first created for John Holland, the half-brother of King Richard II in 1397. That title was rescinded upon Henry IV's accession to the throne two years later. The title was then granted to the former's half-brother, Thomas Beaufort, 1st Earl of Dorset by his nephew Henry V. Following Beaufort's death without heirs in 1426, the title was restored to the Holland family, which held it until the 3rd Duke was attainted in 1461 as a Lancastrian, dying in 1475.
