President Michael D Higgins carried out his first official duty as Head of State when he laid a wreath at a Remembrance Sunday service in Dublin.
The President, who was inaugurated on Friday, attended the Evensong at St Patrick's Cathedral to pay his respects to the 10,000 Irish soldiers killed in World Wars One and Two.
In an address to the congregation, journalist and military historian Kevin Myers spoke of the significance of the President's attendance.
"I begin today by honouring our new President, the commander in chief of our Defence Forces," he said. "Mr President sir, that is surely an honour you will hold closest to your heart - and in this place especially."
Mr Higgins greeted members of the public on his way in and out of the cathedral.
Following hymns, a welcome by St Patrick's Dean the Very Reverend Robert McCarthy, an introduction by his Vicar the Rev Charles Mullen and the address from Mr Myers, President Higgins laid a wreath of poppies at the foot of the cathedral's war memorial.
Others in attendance were Mr Higgins' wife Sabina, Lord Mayor of Dublin Councillor Andrew Montague and a small number of surviving World War Two soldiers.
In his address, Mr Myers spoke of Irish soldiers and nurses who were killed during the wars, including the first victim, a career-airman from Co Cork.
"Those Irish soldiers helped to end a regime of gas chambers and the guillotine, slavery and the firing squad," said Mr Myers. "In those liberated lands in due course emerged what is now the European Union. Our bondholders there might be completely unaware of the debt that they owe the ten thousand Irish dead, who died freeing an unfree Europe.
"But at least we in this cathedral do know it. And we do remember. Which is why we are here today."
