Tim works on the late medieval and early modern political and social history of the British Isles, spanning the period c. 1400-1650. He specialises in the non-English territories of the crown. His early work on Cheshire explored the palatinate’s history during the period between Richard II’s reign and the early seventeenth century. More recently, he has published on Wales, the Isle of Man, Durham, the Channel Islands, and the north of England, and on the ways medieval history, especially the history of the 'Wars of the Roses', was written and re-written in the late medieval and early modern periods.
