July 23, 1803
In opposition to the 1800 Acts of Union, Irish nationalist and rebel Robert Emmet returned to Ireland, after attempting to secure aid from the French, to plan a rebellion. On the evening of July 23, 1803, a rising erupted in Dublin. The rebels attempted to seize Dublin Castle, but failed, and the rising only amounted to a large-scale riot. The British military was able to stop the riot, leaving fifty rebels dead and Emmet to hang on September 20, 1803.
