President Michael D Higgins has said that the dream of the 1916 rebels has not yet been realised.
He was speaking during a ceremony to commemorate James Connolly and the Irish Citizen Army.
Tánaiste Joan Burton and Dublin's Lord Mayor Criona Ní Dhalaigh also attended the event at Liberty Hall.
President Higgins laid a wreath by the statue of James Connolly - remembering all those who died in the Easter Rising.

At the ceremony, the Starry Plough rebel flag was raised on the site it was first flown over Liberty Hall 100 years ago.
It was there that Connolly gave his last address before the Easter Rising, stating boldly that the cause of Labour is the cause of Ireland.
Burton says she was happy to see women featuring prominently in the 1916 commemorations, given they had been written out of the 1966 events:
In an address SIPTU President Jack O'Connor said that Connolly and the Irish Citizen Army did not put the country first, but put people first.
The event also featured a reading by Constance Cowley, who is a relative of Molly O’Reilly - the 15-year-old who raised the green flag of Ireland over Liberty Hall on April 16th 1916.
Speaking at the event, President Higgins said that the republic of which the rebels dreamt has yet to be realised.
He urged people to take up the cause of the Irish Citizen Army - saying there were too many people in poverty, without access to housing, childcare or healthcare.
It brought to a conclusion the commemorations of the centenary this Easter - however, events will continue to mark 1916 for the rest of the year.
Meanwhile, previously unseen material connected to the Easter Rising is going on public display for the first time today.
The new GPO interactive visitor centre on O'Connell Street in Dublin opened to the public this morning, with people queuing from 8.30am to take the 90 minute tour.
These people were among the first to take the tour, and were very impressed by it:
The Witness History Visitor Centre was officially opened last week.
It comes after a busy weekend of events to mark the centenary of the Rising, including the largest military parade in the State's history.
