Daniel O'Connell, often referred to as The Liberator, was an Irish political leader in the first half of the 19th century. One of the most remarkable historical figures in Irish history, he campaigned for Catholic Emancipation, including the right for Catholics to sit in the Westminster Parliament, and repeal of the Act of Union which combined Great Britain and Ireland.

Famous in his day as the most feared lawyer in Ireland, O'Connell tormented judges, terrorised opposing barristers, and won a reputation for saving the lives of so many men who would otherwise have been hanged. He became 'The Counsellor', the fearless defender of the people.

He secured that reputation through his campaign for Catholic emancipation when he founded the first successful mass democratic movement in European history, and became 'The Liberator'.
