A Book of Condolence will be opened at the Mansion House tomorrow so Dubliners can pay their respects Martin McGuinness, who has died at the age of 66.
He had stepped down as Northern Ireland's Deputy First Minister in January and had been unwell for several months.
In over forty years in politics he went from being an IRA volunteer to being leader of a peaceful power-sharing government.
In his early 20s he joined the Provisional IRA and quickly rose through its ranks, becoming second-in-command in his native Derry by the time of Bloody Sunday, when he was just 21.
Shortly afterwards he was jailed for possession of explosives, south of the border.
On his release, while insisting he had left the IRA, he became more prominent in Sinn Féin and a serious figure around the negotiating table.
By the time of the talks that led to the Good Friday Agreement and power sharing in the North, the former IRA Commander was now leading the charge for peace.
In 2007 he became Deputy First Minister and eventually shared power with former political opponent, Unionist Ian Paisley.
The two were so friendly they were known as 'the Chuckle brothers'.
A row over a flawed renewable heat scheme caused McGuinness to collapse the northern government just two months ago and retire from politics with a rare condition called amyloidosis.
A number of people have paid tribute to the former Northern Ireland Deputy First Minister on Twitter:
Speaking this morning Sinn Féin President Gerry Adams TD said:
“Throughout his life Martin showed great determination, dignity and humility and it was no different during his short illness.
“He was a passionate republican who worked tirelessly for peace and reconciliation and for the re-unification of his country. But above all he loved his family and the people of Derry and he was immensely proud of both".
In a statement, President Michael D. Higgins said,
"The world of politics and the people across this island will miss the leadership he gave, shown most clearly during the difficult times of the peace process, and his commitment to the values of genuine democracy that he demonstrated in the development of the institutions in Northern Ireland.
His death leaves a gap that will be difficult to fill. May he rest in peace."
The Lord Mayor says the Book of Condolence will be open at the Mansion House form 10am to 4pm tomorrow and Thursday the 23rd of March.
Brendan Carr says “I would like to offer the people of Dublin this opportunity to pay their respects to Martin McGuinness who was a pivotal figure in the Northern Ireland peace process. Through his work over the past twenty years on the ongoing peace process in Northern Ireland, he has had a positive impact on the citizens of Dublin and the island of Ireland".
