Robert Emmet is born into a wealthy Protestant Dublin family. He would go on to become one of Ireland's most famous (but also pretty incompetent) rebels who would be executed for high treason.
In 1803, Emmet would be captured in Dublin on August 25th following a hopelessly unsuccessful attempt at insurrection. In one sense, Emmet's rebellion deserves little more than a footnote in history. The rebellion itself was more a riot than a full scale insurrection, but it garnered major publicity when the Lord Chief Justice of Ireland was killed in the affray.
British authorities hang six IRA volunteers for crimes of high treason and murder. There is some strong evidence to suggest at least some of the men were innocent of the crimes they were accused of although all had been involved in violent acts against British forces in Ireland.
More executions on this date in Irish history. This time the new Irish government which has taken a strong stance against anti-treaty activists executes sixteen anti-Treatyites between March 12-March 14.
