William Pitt the Younger had promised that Catholic Emancipation would accompany the Act of Union of 1800, which is to say that various restrictions on Roman Catholics would be abolished alongside the Act of Union. However due in large part to George III's opposition to any form of relaxation of restrictions on Catholics, Peel was unable to bring in Catholic Emancipation and resigned.
Now suppose Peel was able to persuade, force or cajole the King into agreeing to Catholic Emancipation (as the Duke of Wellington did IOTL to George IV, who supposedly wept as he gave his assent to the Act). What would the effects of this be? How would Catholic Emancipation twenty nine years early effect the development of Irish Nationalism? How would other events be changed by Pitt not resigning over the issue?
