President Michael D Higgins has paid tribute to the central role Irish women have played in Irish history.
He was speaking at an event to commemorate the foundation of Cumann na mBan 100 years ago.
Mr Higgins said that there was still a long way to go to achieve full equality for men and women, particularly at levels of representation in public life.
Speaking at the State Ceremony to mark the centenary of the foundation of the organisation at Glasnevin cemetery, he said women had suffered more than most in Irish history, and yet he said their stories and their voices were often silenced.
Minister for Arts, Heritage and the Gaeltacht Jimmy Deenihan also took part in a commemoration ceremony to mark the day, along with members of the Defence Forces.
A wreath was laid at the grave of Elizabeth O'Farrell, as a symbol of the contribution made by the many thousands of other members of Cumann na mBan.
A guard of honour made up completely of female personnel of the Defence Forces also took part in the ceremony.
A series of events are being held over the next few days, including a conference about Cumann na mBan in Collin's Barracks and a special exhibition at Glasnevin cemetery, as part of the Decade of Centenaries programme.
