Clontarf had an important role in the career of the prominent Irish nationalist leader Daniel O'Connell who sought to hold on this location, symbolic because of its association with the Battle of Clontarf in 1014, a mass meeting calling for repeal of the Act of Union. The meeting was banned by then-Prime Minister, Sir Robert Peel, and despite appeals from his supporters, O'Connell refused to defy the authorities and he called off the meeting, as he was unwilling to risk bloodshed.
