In the years following the Rising, the events of Easter week would endure as a significant part of Ireland’s national memory. Although the Treaty creating the Irish Free State was accepted in 1922, conflict continued for many years afterwards between the Irish and the Northern Irish, who remained a part of the United Kingdom. Thus, clinging to the ideals of independence as established during the Rising was significant for the Irish Republic in the years of trouble. Even before one year had passed, the Irish and Irish Americans were already holding commemorations and publishing works to memorialize the Easter Rising.

In later years, anniversaries of the rising were marked by publications, speeches, and cultural events, such as plays about the Rising.  Many of these various forms of commemoration reflected and responded to current events in Ireland. Now, as the 100-year anniversary approaches, the Irish people once again seek memorialize the sacrifices of the men and women who fought for Ireland’s independence.
