William Catesby

Sir William Catesby (1450 – 25 August 1485) was one of Richard III of England's principal councillors. He also served as Chancellor of the Exchequer and Speaker of the House of Commons during Richard's reign.

The son of Sir William Catesby of Ashby St Ledgers, Northamptonshire (died 1478) and Philippa, daughter and heiress of Sir William Bishopston, he was trained for the law in the Inner Temple. As an aspiring lawyer Catesby initially progressed in the service of William, 1st Lord Hastings. He married Margaret, daughter of William La Zouche, 6th Baron Zouche of Harringworth; the couple had three sons. Upon the death of his father he inherited a large number of estates in the English Midlands and was land-agent for many others. He was a member of the Council that ruled during the reign of Edward V. After Richard was enthroned, Catesby was one of King Richard's closest advisors. He served as Chancellor of the Exchequer, and as Speaker of the English House of Commons during the Parliament of 1484, in which he sat as knight of the shire for Northamptonshire. He also received a substantial grant of land from the king, enough to make him richer than most knights.

In July 1484, William Collingbourne, a Tudor agent, tacked up a lampooning poem to St. Paul's Cathedral, which mentions Catesby among the three aides to King Richard, whose emblem was a white boar:

The Catte, the Ratte and Lovell our dogge rulyth all Englande under a hogge.
