Celebrations began on Easter Sunday on April 10, 1966 when a Military parade took place in Dublin.
An estimated 200,000 people attended the march as it paraded down O'Connell Street before stopped outside the General Post Office, the headquarters of the 1916 Easter Rising leaders.
The then Irish president Éamon de Valera took the salute with an estimated 900 veterans of the Easter Rising by his side.

Religious services were held across the country on Easter Monday in remembrance of the veterans of the Rising.
