Daniel O'Connell (6 August 1775 – 15 May 1847); often referred to as The Liberator, or The Emancipator, is an Irish political leader in the first half of the 19th century.

He campaigns for Catholic Emancipation—including the right for Catholics to sit in the Westminster Parliament, denied for over 100 years—and repeal of the Act of Union that combined Great Britain and Ireland.
