the 1916 Easter Rising was the first major uprising since the end of the 18th century, but it didn’t go well and was quashed within a week. popular opinion of the rebels at the time was not favorable; no one joined the cause and the British were able to quash the uprising entirely. they did produce and sign a proclamation of independence, which the signers knew might likely lead to their executions (which it did).
the general post office in the middle of O’Connell Street was the center of the action (though the taking of the Four Courts was crucial as well). there’s a good narrative of events here.
word of the executions got out and turned the tide of public opinion. despite the best efforts of the British, details made their way into newspapers and other publications. although the executions were carried out in the isolated hard labor yard (which could not be seen from elsewhere in the prison), the priests present to administer last rites were appalled by the treatment of the condemned (and particularly James Connolly) and felt no compunction about sharing the horrors they witnessed. it was these reports that re-cast and illuminated for the general Irish populace the ideals for which the rebels fought and died and, ultimately, which shifted public opinion towards demanding independence.
the far end of the yard in the second picture is where all but one of the leaders of the Easter Rising were executed. the final man, James Connolly, was executed on the spot directly to my right as I took this picture.
