Cumann na mBan (;
The Irishwomen's Council), abbreviated
CnamB, 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 Volunteers.
