The annual commemoration has taken place in Dublin to remember the leaders of the 1916 Easter Rising.
The ceremony is held every May at the Church of the Most Sacred Heart in Arbour Hill.
President Michael D Higgins, Taoiseach Simon Harris, Tánaiste and Minister for Foreign Affairs and Defence Micheál Martin and British Ambassador to Ireland Paul Johnston were among those in attendance.
The ceremony included speeches and a wreath-laying ceremony at the graves of the rebellion's leaders.
This morning's commemoration included a mass which was led by the Bishop of Killaloe Fintan Monahan.
In his homily, Bishop Monahan addressed the families of the executed leaders.
He said their story was intertwined with the story of the Irish nation.
Bishop Monahan told them they could be "rightly proud" that they carry in their DNA the spirit of freedom, which enabled their relatives to lay down their lives for freedom.
"The 1916 executions deprived your families of beloved ancestors. Some of the most poignant stories of the post-Easter time in 1916 are the stories of the visits of children to their condemned relatives and their final goodbyes. These losses were the sacrifices that your families made as a life-giving gift to our nation," he said.
Turning to present-day fights for freedom he said hearts were heavy with a new story of oppression and the desire to be free from it.
"We see the plight of those seeking refuge in our land and the root causes of this in many war torn parts of the world. Our knowledge of the world is now instantaneous but our sadness and helplessness in the face of oppression is as old as humanity," he said.
