The Young Ireland rebellion of 1848 was launched in frustration with the failure of Daniel O'Connell's Repeal Association movement to secure the repeal of the Union, or self-government for Ireland. The Young Irelanders had previously supported O'Connell until he cancelled plans for a mass rally under British threat of force. The 1848 rebellion was a failure; launched during the Great Irish Famine, it did not address any of the social and economic questions of the day, and weakened the parliamentary movement of the recently deceased Daniel O'Connell.
