The title of Earl of Athlone has been created three times. It was created first in the Peerage of Ireland in 1692 along with the subsidiary title of Baron Aghrim. These titles became extinct in 1844 upon the death of the 10th Earl. The second creation was in the Peerage of the United Kingdom, as a subsidiary title of the Dukedom of Clarence and Avondale, and was conferred in 1890 upon HRH Prince Albert Victor, the eldest son of the Prince of Wales. He died in 1892, when the title became extinct. The title was recreated in 1917, also in the Peerage of the United Kingdom for the former Prince Alexander of Teck, younger brother of Queen Mary, along with the subsidiary title of Viscount Trematon. The titles became extinct upon the death of the first earl in 1957.
