Dorothy Macardle (1889-23 December 1958) was an Irish author and historian. Her book, The Irish Republic, is one of the most frequently cited narrative accounts of the Anglo-Irish War and its aftermath. She is generally regarded as the definitive contemporary historian from the republican anti-treaty perspective.
When the republican movement split in 1921-22 over the Anglo-Irish Treaty, as referred to above, Macardle sided with Éamon de Valera and the anti-Treaty Irregulars. She was imprisoned by the fledgling Free State government in 1922, during the Civil War, and served time in both Mountjoy and Kilmainham Gaols.
Macardle recounted her Civil War experiences in Earthbound: Nine Stories of Ireland (1924). Macardle became a playwright in the next two decades. In her dramatic writing she used the pseudonym Margaret Callan. During this time she worked as a journalist at the League of Nations. She also researched her mammoth book The Irish Republic which was first published in 1937. Her political opponents considered her to be a hagiographer and apologist for her extreme political views.
She died in 1958 and the age of 69 of cancer in hospital in Drogheda. Though she was somewhat disillusioned with the new Irish State (in particular, regarding its treatment of women), she left the royalties from The Irish Republic to her close friend Éamon de Valera, who wrote the foreword to the book. De Valera visited her when she was dying and prayed constantly, but without succees, for her conversion from Protestantism to Roman Catholicism.
