The title of Viscount Charlemont was created in the Peerage of Ireland in 1665. The Viscount bears the subsidiary title of Baron Charlemont (1620). The fourth Viscount was created Earl of Charlemont in 1763 and the second Earl was created Baron Charlemont in the Peerage of the United Kingdom in 1837, but these titles became extinct on the death of the third Earl in 1892.
James Caulfeild, 1st Earl of Charlemont KP PC (August 18, 1728 – August 4, 1799) was an Irish statesman.
The title of Charlemont descended from Sir Toby Caulfeild (1565–1627) of Oxfordshire, England, who was given lands in Ireland, and created Baron Charlemont (the name of a fort on the Blackwater), for his services to King James I in 1620.
Lord Charlemont is historically interesting for his political connection with Henry Flood and Henry Grattan; he was a cultivated man with literary and artistic tastes, and both in Dublin and in London he had considerable social influence.
James, Earl of Charlemont, was born in Dublin, the 18th of August, 1728, and succeeded to the title when but six years old, upon the demise of his father.
Lord Charlemont afterwards spoke of this election as most flattering to himself, and as an event, among many others of the same kind, by which the dispensations of Heaven are peculiarly marked, extracting satisfaction from the bosom of misfortune.
The greater portion of Lord Charlemont's life was now spent either at the house he had built in Palace Row, or at his elegant villa near Dublin, which he had called Marino, from its proximity to the sea, in the enjoyment of the society of his friends, or engaged in literary occupations.
