In September 1791, Tone published "An Argument on behalf of the Catholics of Ireland", signed "A Northern Whig". It displayed the growing breach between Whig patriots like Henry Flood and Henry Grattan, who sought Catholic emancipation and parliamentary reform without severing the tie to England. Tone expressed contempt for the constitution Grattan obtained from the British government in 1782. Himself an Anglican, Tone urged co-operation between the religions in Ireland as the only means of obtaining redress of Irish grievances. The British government had just passed the Roman Catholic Relief Act 1791, but the Dublin parliament was in no hurry to do so.
