Constance Georgine Markievicz, also known as Countess Markievicz and Madame Markievicz, was an Irish politician, revolutionary, nationalist, suffragist, socialist, and the first woman elected to the Westminster Parliament. She was elected Minister for Labour in the First Dáil, becoming the second female cabinet minister in Europe. She served as a Teachta Dála for the Dublin South constituency from 1921 to 1922 and 1923 to 1927. She was a Member of Parliament (MP) for Dublin St Patrick's from 1918 to 1922.

Na Fianna Éireann, known as the Fianna, is an Irish nationalist youth organisation founded by Constance Markievicz in 1909, with later help from Bulmer Hobson. Fianna members were involved in setting up the Irish Volunteers, and had their own circle of the Irish Republican Brotherhood (IRB). They took part in the 1914 Howth gun-running and in the 1916 Easter Rising. They were active in the War of Independence and many took the anti-Treaty side in the Civil War.
