What did 'Daniel o' connell' achieve?

Daniel O'Connell, known as the "Liberator," was a prominent Irish nationalist leader in the 19th century who campaigned for Catholic Emancipation, which aimed to remove the restrictions on Catholics in Ireland. His efforts culminated in the passage of the Catholic Relief Act of 1829, allowing Catholics to sit in the British Parliament. O'Connell also advocated for Irish self-governance and was instrumental in the formation of the Repeal Association, which sought to repeal the Act of Union that merged Ireland with Great Britain. His legacy is marked by his commitment to non-violent protest and civil rights.
