On July 23, 1803, Robert Emmet led a failed rebellion in Dublin, attempting to seize Dublin Castle and proclaim an Irish republic. The rebellion was poorly organized and quickly suppressed, but Emmet's trial and execution transformed him into a martyr for Irish independence. Emmet's speech from the dock, in which he declared that he would not have his epitaph written until Ireland was free, became a rallying cry for future generations.

Robert Emmet's rebellion and his speech from the dock are among the most powerful subjects in Irish nationalist poetry. Emmet's words have been quoted and re-quoted in verse, and his martyrdom inspired the poetry of the Young Irelanders and later nationalists. His story is a central theme in the poetry of the 19th century, representing the ideal of the romantic revolutionary who sacrifices everything for his country.
