John Holland, 1st Duke of Exeter

John Holland, 1st Duke of Exeter and Earl of Huntingdon (c. 1352–1400), was Richard II's half-brother and loyal supporter. Made a Knight of the Garter in 1381, he killed Ralph Stafford during the 1385 Scottish expedition, forfeiting his lands, restored in 1386.

In 1386 he married Elizabeth, daughter of John of Gaunt. He became Earl of Huntingdon in 1388. After helping arrest the Duke of Gloucester in 1397 he became Duke of Exeter, losing the title when Henry IV took the throne in 1399.

In January 1400 he joined the Epiphany Rising to restore Richard; on its failure he was captured in Essex and beheaded on 16 January 1400.
