Statue of Daniel O'Connell outside St Patrick's Cathedral

Dónal Ó Conaill (6 August 1775 – 15 May 1847; English: Daniel O'Connell), often referred to as The Liberator, or The Emancipator, was an Irish political leader in the first half of the 19th century. He campaigned for Catholic Emancipation—the right for Catholics to sit in the Westminster Parliament, denied for over 100 years—and repeal of the Act of Union which combined Great Britain and Ireland.
