Richmond was part of the lands of the earldom of Richmond, which was intermittently held by the Dukes of Brittany until the 14th century. When John V, Duke of Brittany died in 1399 Henry IV took possession of Richmond. In 1453, the earldom was conferred on Edmund Tudor, and became merged in the crown when Edmund's son Henry became king, as Henry VII in 1485.
