A rare legal mind who mastered the courtroom and the medieval history archives
In short: Jonathan Sumption is a polymath who balanced a record-breaking career as a barrister with a rigorous life as a historian. After rising to the UK Supreme Court directly from the bar, he completed a monumental five-volume history of the Hundred Years War, proving that legal precision and historical scholarship coexist.
Jonathan Sumption’s career is defined by a rare duality. While he became one of Britain's most prominent barristers, earning record-breaking fees for high-stakes litigation—including the defence of Roman Abramovich—he simultaneously maintained a dedicated life as a medieval historian. His academic roots were planted at Magdalen College, Oxford, where he served as a Fellow by Examination from 1971 to 1975. It was during this period that he produced his initial work on medieval pilgrimage, a foundation for the extensive historical research he would pursue for decades alongside his legal practice.
The scale of his historical output is perhaps best represented by his five-volume narrative history of the Hundred Years War, a project he brought to completion in 2023. This work sits alongside his legal contributions, which include serving as a Justice of the Supreme Court from 2012 to 2018. His appointment was notable for its rarity; he was one of only five barristers since 1873 to transition directly to the highest court without prior full-time judicial experience. His legal career saw him involved in major cases, such as the Hutton Inquiry and the Railtrack shareholders' action.
Beyond the courtroom and the library, Sumption has engaged deeply with the arts and public discourse. He served as a governor of the Royal Academy of Music for over two decades and as a director of the English National Opera. His post-judicial life has been equally active, marked by the publication of his Reith Lectures, 'Trials of the State', and ongoing research into the French Wars of Religion. Whether analyzing the decline of politics or the intricacies of medieval conflict, Sumption’s work reflects a lifelong commitment to the rigorous study of power and its institutional constraints.
