Daniel O'Connell (1775 – 1847), known as The Liberator or The Emancipator, was Ireland's predominant political leader in the first half of the nineteenth century who championed the cause of the down-trodden catholic population. He campaigned for Catholic Emancipation and Repeal of the Union between Ireland and Great Britain. He is remembered in Ireland as the  founder of a non-violent form of Irish nationalism and also for the mobilisation of the Catholic community as a political force in order to achieve emancipation.
