Robert Stewart, Later 1st Marquess of Londonderry

The Portrait of Robert Stewart, 1st Marquess of Londonderry, depicts a prominent figure of Ireland’s Anglican Ascendancy, despite his Scottish and Presbyterian roots. Painted in a Neoclassical style, the portrait emphasizes his stature as a landowner, Irish Volunteer, and politician. The artist captures Londonderry's confident demeanor, reflecting his political success fueled by strategic marriages and his son Viscount Castlereagh’s rise. Notably, in 1798, he gained notoriety for declining to intervene in the execution of Presbyterian minister James Porter, an event that marked his complex ties to religion and politics during tumultuous times.
