Many reformers despaired of peaceful change, particularly in the lack of Tithe reform, and this led on to instances of Catholic support for the abortive 1798 rebellion. During the rebellion the Irish Catholic bishops supported the government line. The subsequent passing of the Act of Union of 1801 was intended to include Catholic Emancipation, as power was moved from the hands of the Protestant Ascendancy to the London Parliament. This was agreed by most of the British Cabinet, including William Pitt, and they resigned when it was not effected. The personal opposition of George III ensured that no change would be forthcoming during his reign.
