Jane Wyse Power was an Irish activist, feminist, politician and businesswoman. She was a founder member of Sinn Féin and also of Inghinidhe na hÉireann. She rose in the ranks to become one of the most important women of the revolution. As President of Cumann na mBan, she left the radicalised party and formed a new organisation called Cumann na Saoirse, holding several senior posts in the Dáil during the Free State.

Cumann na mBan, abbreviated C na mB, is an Irish republican women's paramilitary organisation formed in Dublin on 2 April 1914, merging with and dissolving Inghinidhe na hÉireann, and in 1916, it became an auxiliary of the Irish Volunteers. Although it was otherwise an independent organisation, its executive was subordinate to that of the Irish Volunteers, and later, the Irish Republican Army.
