John Marshall

RHS Centenary Fellow 2023 - 2024

John is a fourth year PhD candidate at Trinity College Dublin, having previously obtained a BA and MA from Dublin City University. He is currently completing his thesis entitled 'Power and patronage across the Plantagenet dominions: the making and breaking of the Marshal assemblage, 1189-1247'.

John's Research

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.  Overall, John’s project uses one family to analyse the vulnerability of empire in thirteenth-century Britain and Ireland. By utilising a transnational framework, his research nuances events typically isolated within nation-centred historiographies and demonstrates the dichotomous fluidity and detachment in existence between the different spheres of the Plantagenet dominions in the thirteenth century. Over the course of his Fellowship at the IHR, John will produce the first edition of the partition of the Marshal estates in 1247 after the male line of the family died out.
