Alice Stopford Green was an Irish historian and nationalist.
She was born Alice Sophia Amelia Stopford in Kells, County Meath. Her father Edward Adderley Stopford was Rector of Kells and Archdeacon of Meath. Her paternal grandfather was Edward Stopford, the Church of Ireland Bishop of Meath, and she was a cousin of Stopford Brooke and Mother Mary Clare. From 1874 to 1877 she lived in London where she met the historian John Richard Green. They were married in Chester on 14 June 1877. He died in 1883. John Morley published her first historical work Henry II in 1888.
In the 1890s she became interested in Irish history and the nationalist movement as a result of her friendship with John Francis Taylor. She was vocal in her opposition to English colonial policy in South Africa during the Boer Wars and supported Roger Casement's Congo Reform movement. Her 1908 book The Making of Ireland and its Undoing argued for the sophistication and richness of the native Irish civilisation. Stopford Green was active in efforts to make the prospect of Home Rule more palatable to Ulster Unionists. She was closely involved in the Howth gun-running.
