The Life and Career of Sir William Plumpton from 1404 to 1480

Abstract Plumpton, an ardent Lancastrian, received protection and patronage from the Percies and was loyal to them throughout his life. He enjoyed exceptional local power from 1438 to 1460 as steward of the Honour of Knaresborough. He served as a JP, an MP, sheriff, and steward of Northumberland's Spofforth and other estates in Yorkshire, as well as overseeing his own lands in four counties. Detailed study of the Knaresborough court rolls and Duchy of Lancaster records led to a re-examination of the dating and interpretation of his officeholding and career, particularly in the 1460s and 1470s. He did not regain the stewardship in 1460s, as was believed, but was re-instated in 1471; he was replaced within a few years, probably because of corruption. Principal officeholders at Knaresborough, 1438–1500, are listed, and further unpublished material includes cases which the litigious Plumpton initiated in King's Bench from 1461. His attitudes, often cheating and ruthless, to friends and family, are examined, and his career compared with those of other members of the gentry; Plumpton's status is examined, this being aided by the findings from a rare unpublished fifteenth-century subsidy roll.
