Markiewicz, Constance Georgine, Countess (märkyāˈvĭts) [key], 1868–1927, Irish politician and patriot. A member of Sinn Féin, she was sentenced to death for her militant part in the Easter Rebellion of 1916 but was released in 1917. The daughter of an Irish baronet, she was married (1900) to a Polish count. In 1918 she was the first woman to be elected to the British House of Commons, but she never took her seat. Instead she sat in the Dáil Éireann until her death.
