1775-1847. Irish politician, called `the Liberator'. In 1823 he founded the Catholic Association to press Roman Catholic claims. Although ineligible, as a Roman Catholic, to take his seat, he was elected member of Parliament for County Clare 1828 and so forced the government to grant Catholic emancipation. In Parliament he cooperated with the Whigs in the hope of obtaining concessions until 1841, when he launched his campaign for repeal of the union. His reserved and vacillating leadership and conservative outlook on social questions alienated his most active supporters, who broke away and formed the nationalist Young Ireland movement.
