On this day 100 years ago, the Easter Rising began.
It was a day later than originally planned and on a much smaller scale.
Preparations for an insurrection in Ireland had begun soon after the outbreak of the First World War and were carried out by a small, radical group of separatist nationalists.
The date they had set for the Rising was Easter Sunday, 23 April 1916.
But plans unravelled in the days beforehand when a shipment of German arms was intercepted off the coast of Kerry and confusion over conflicting orders led to the cancellation of Irish Volunteer manoeuvres that were to provide the cover for the uprising.
Undeterred, the rebel conspirators met on Easter Sunday at Liberty Hall and decided to salvage something from the wreckage of their plans.
The Rising would go ahead – but on the following day, 24 April 1916.
Here, Century Ireland takes you through that day and how events unfolded:
