Áine Ceannt (née Ní Bhraonáin), Irish revolutionary activist and humanitarian leader, is born Frances Mary Brennan at 28 Upper Camden Street, Dublin, on September 23, 1880.

Brennan is the daughter of Francis Brennan, who himself is a Fenian earlier in his life, and sister of Lily O’Brennan and Kathleen O’Brennan. Her mother is Elizabeth Anne Butler. She is educated in the Dominican College, Eccles Street, and adopts the name Áine upon joining the Gaelic League. It is through her Irish language activism that she meets her future husband, Éamonn Ceannt, whom she marries on June 7, 1905. Their son, Ronan, is born in June 1906. A convinced republican, she joins Cumann na mBan on its foundation in 1914. She writes and delivers dispatches during the Easter Rising. Her husband is one of the signatories of the Proclamation of the Irish Republic and is executed by the British at Kilmainham Gaol on May 8, 1916.

Newly widowed, Ceannt continues her republican activism, serving as Vice-President of Cumann na mBan and as a member of the Sinn Féin Standing Committee. She also plays a role in the development of the Sinn Féin Courts, a parallel legal system designed to offer an alternative to the British courts.

Ceannt is ardently opposed to the signature of the Anglo-Irish Treaty in December 1921. She is imprisoned by the Irish Free State government during the Irish Civil War in Mountjoy Prison for her anti-Treaty activity. Throughout the war, she serves at the highest levels within anti-Treaty Sinn Féin. In the years that follow, she spearheads efforts to secure state compensation for the widows and the children of those who had died in 1916 and in the Irish War of Independence. She serves as the head of the Children’s Fund of the Irish White Cross, an American-funded humanitarian organisation founded to assist victims of unrest in Ireland. She is a member of the Executive Committee of the Irish Red Cross.

In her later years, Ceannt moves to Churchtown, Dublin. She dies on February 2, 1954, in her home, Inis Ealgan, and was buried in Dean’s Grange Cemetery, situated in the suburban area of Deansgrange in Dún Laoghaire–Rathdown, County Dublin.
