In 1908, Markievicz became actively involved in nationalist politics in Ireland. She joined Sinn Féin and Inghinidhe na hÉireann ('Daughters of Ireland'), a revolutionary women's movement founded by the actress and activist Maud Gonne, muse of W. B. Yeats. Markievicz came directly to her first meeting from a function at Dublin Castle, the seat of British rule in Ireland, wearing a satin ball-gown and a diamond tiara. Naturally, the members looked upon her with some hostility. This refreshing change from being "kowtowed"-to as a countess only made her more eager to join. She performed with Maud Gonne in several plays at the newly established Abbey Theatre, an institution that played an important part in the rise of cultural nationalism. In the same year, Markievicz played a dramatic role in the women's suffrage campaigners' tactic of opposing Winston Churchill's election to Parliament during the Manchester North West by-election, flamboyantly appearing in the constituency driving an old-fashioned carriage drawn by four white horses to promote the suffragist cause. A male heckler asked her if she could cook a dinner, to which she responded, "Yes. Can you drive a coach and four?" Her sister Eva had moved to Manchester to live with fellow suffragette Esther Roper and they both campaigned against Churchill with her. Churchill lost the election to Conservative candidate William Joynson-Hicks, in part as a result of the suffragists' dedicated opposition.
