Irish nationalist Daniel O'Connell is arrested by the British on charges of criminal conspiracy.

Daniel(I) O’Connell, hailed in his time as The Liberator, was the acknowledged political leader of Ireland's Roman Catholic majority in the first half of the 19th century. His mobilisation of Catholic Ireland, down to the poorest class of tenant farmers, secured the final instalment of Catholic emancipation in 1829 and allowed him to take a seat in the United Kingdom Parliament to which he had been twice elected.
