John Marshall is an RHS Centenary Fellow, held jointly with the Institute of Historical Research, University of London. John is a fourth year PhD candidate at Trinity College Dublin, having previously obtained a BA and MA from Dublin City University.
John’s research analyses transnational lordship and politics in thirteenth-century Britain and Ireland. John’s thesis focuses on the Marshal earls of Pembroke and lords of Leinster, in particular how their influence on the ‘peripheries’ of the Plantagenet empire in Ireland and Wales brought them influence and patronage at the core. His thesis will also provide the first edition of the partition of the Marshal estates in 1247 after the male line of the family died out.
In addition to his membership with the RHS, John is also an associate member of the AHRC-funded Noblesse Oblige research network and has published on aspects of his research in History: The Journal of the Historical Association (108:382) and Irish Historical Studies (2023).
