 After the 'Kingmaker' went over to Henry VI's side in 1470, Richard, Duke of Gloucester, Edward IV's brother, received most of the Neville lands in Cumbria and Yorkshire, becoming Warden of the West March and Sheriff of Cumberland.Most of the northern nobles backed Richard's bid to become king in 1483.However, at the Battle of Bosworth Field, Henry Percy, 4th Earl of Northumberland failed to support Richard (leading a distrustful Henry VII of England to make Lord Dacre the Warden of the West March).
