Following the Acts of Union 1800, Pitt sought to inaugurate the new United Kingdom of Great Britain and Ireland by granting concessions to Roman Catholics, who formed a 75% majority of the population in Ireland, by abolishing various political restrictions under which they suffered. The king was strongly opposed to Catholic Emancipation; he argued that to grant additional liberty would violate his coronation oath, in which he had promised to protect the established Church of England. Pitt, unable to change the king's strong views, resigned on 16 February 1801, so as to allow Henry Addington, his political friend, to form a new administration. At about the same time, however, the king suffered a renewed bout of madness, with the consequence that Addington could not receive his formal appointment. Though he had resigned, Pitt temporarily continued to discharge his duties; on 18 February 1801, he brought forward the annual budget. Power was transferred from Pitt to Addington on 14 March, when the king recovered.
