Portrait of Robert Henley, 2nd Earl of Northington (1747-1786), Lord Lieutenant of Ireland

Reynolds painted Robert Henley, 2nd Earl of Northington, around 1782, in his capacity as Lord Lieutenant of Ireland — the Crown's representative in Dublin responsible for managing Anglo-Irish relations during a period of considerable political tension. The American Revolutionary War had energized the Irish Volunteer movement, and the Grattan Parliament of 1782 had extracted significant concessions from London, creating an atmosphere of political excitement and instability that made the office of Lord Lieutenant particularly demanding. Reynolds's portrait, commissioning a formal record of high office, participates in the tradition of vice-regal portraiture that stretched back through a long line of Lord Lieutenants depicted in official state portraits. Reynolds was highly practiced in this genre — portraying men of state required the ability to project institutional authority while maintaining individual characterization, a balance that lesser painters struggled to achieve. The National Gallery of Ireland's collection of Reynolds works includes several Anglo-Irish political subjects, reflecting the sustained patronage that the Protestant Ascendancy directed toward the most prestigious British portraitist.

The formal portrait presents the politician with authority. Reynolds's handling creates an image that balances official dignity with personal character.
