Fr Séamus Murphy SJ is an Irish Jesuit priest who is currently teaching philosophy at Loyola University Chicago.

"On the first day of the Rising, the Volunteers and Irish Citizen Army (ICA) members deliberately killed some civilians and unarmed Dublin Metropolitan Police constables.

They staged the Rising in the most densely populated part of Ireland, even choosing the South Dublin Union, full of sick and elderly like its descendant St James's Hospital, as one place to fight. There were far more civilian (260) than rebel (82) or combined military and police (142)deaths, and responsibility for their deaths lies primarily with the leaders of the Rising."

"With no authority, the Rising's leaders declared a republic, nominated themselves as its government, and shot anybody in their way.

As is clear from what Pearse, Connolly and Clarke stated at the time, democratic elections were beneath them. They believed that the people did not want an independent republic: they were determined to start a chain of events that would, by political emotional blackmail, compel the Irish people to 'want' it.

Nor did they represent the Volunteers or even the IRB in full. As Pearse himself admitted, they subverted the Volunteers, lying to Eoin MacNeill about their plans. They excluded IRB leaders (like Bulmer Hobson) who did not agree with them. "

"Militarily insignificant, the Rising had no political effect on Britain, strengthened extreme northern unionists, and was politically devastating for the IPP, as Redmond and many others understood at once.

In the Rising, the unelected gunmen defeated the elected representatives. That wrought dreadful long-term damage to Irish political culture, as regards democracy, peace, politics rather than violence, the rule of law, human rights, tolerance and pluralism."
