The annual 1916 Commemoration Ceremony has taken place at Arbour Hill in Dublin.
President Michael D Higgins, Taoiseach Micheál Martin and Tánaiste Simon Harris attended, along with other elected representatives, members of the judiciary and family members of the leaders and others who fought in the 1916 Rising.
A guard of honour was formed by the 27th Infantry Battalion at Aiken Barracks in Dundalk.
Flag officers from the Army, Air Corps and Naval service were in attendance along with the Army band who played under sparkling blue skies.
Inside the Church of the Most Sacred Heart, a mass was held with interfaith representatives, to remember those who fought in 1916.
Afterwards, President Higgins laid a wreath at the grave of the executed 1916 leaders, commemorating all those who died.
This is the 101st State commemoration at Arbour Hill - with ceremonies beginning after the end of the Civil War in 1923.
Mr Harris said it was a privilege to host the event as Minister for Defence in the company of relatives of executed leaders.
Family members there to remember their loved ones spoke of their heroism in the fight for the Ireland that is known today.
Ruth Plunkett, a relative of Joseph Plunkett, one of the signatories of the Proclamation of the Republic, said it's a celebration of family.
"But it's also an acknowledgement of Joe and of his participation and why it matters to have courage. We come as relatives ... to remember their own family. But I think if the country remembers courage, that's what you'd like."
Stephen Plunkett, another relative of Joseph Mary Plunkett, as he put it, said there are not many ceremonial events in Ireland, and this is a very unusual one.
"It's a very difficult time in the world, and it's funny because we had speeches from a Jewish representative, an Islamic representative, all talking about peace, and we could really do with that in the world right now.
"So, coming here is just a way of expressing solidarity with other people and with our generations who have gone before. It's a very nice ceremony, and it's very important to people."
Úna O’Callanáin, granddaughter of Michael Mallin, said she thought the ceremony was "absolutely beautiful" and said she was delighted to hear more Irish used in the event.
She said her father was Mr Mallin’s eldest son, and was traumatised to lose his father at the age of 12, when he was executed.
She said it wasn’t until 50 years after the event that her father began to open up about it all.
Canadian Erin Robinsong said she grew up steeped in Joseph Plunkett’s poetry, and this was her first time to attend the ceremony and visit her relative's grave.
She said the Easter Rising is very much part of history now, saying: "I think that they were so brave and so sure about the world that they wanted to see, but they didn't know what would happen... they just put everything into creating that, and now we get to live in that space that they made."
