Ireland marked the 100th anniversary of the Easter Rising on Sunday this weekend.
The Easter Rising, a rebellion which took place in 1916, is considered to have foreshadowed Ireland’s independence from Britain.
The ceremony in Dublin will include a 4.4-kilometer (2.7-mile) parade for hundreds of thousands of spectators.
Irish President Michael D. Higgins will participate in the ceremony laying a wreath at the General Post Office (GPO) rebel headquarters.
Higgins said Ireland is still trying to achieve a comprehensive republic.
"We can see that in many respects, we have not fully achieved the dreams and ideals for which our forebears gave so much," he said.
After the wreath-laying by president Higgins a minute of silence will be held for those who fought for Irish independence.
The relatives of the people who fell in battle are also invited to lay wreaths. Around 5,000 relatives have been invited to the ceremony.
The uprising began on April 24, 1916, when over 1,000 militants took over prominent buildings in the city center.
The Rising "gave people the courage to believe we could achieve total independence," Eamon O'Cuiv, deputy leader of political party Fianna Fail and grandson of 1916 rebel Eamon de Valera, told Agence France Presse.
But for some the celebrations are controversial due to the armed nature of the uprising.
During the anniversay events are held to remember the British soldiers who died in the rising, with the Irish government saying "inclusivity" is important.
But Northern Ireland's First Minister Arlene Foster - the leader of the pro-British Democratic Unionist Party - stated she will not be a part of the commemorations because they are "a very violent attack on the state."
