George signed the Quebec Act of 1774, abolishing William of Orange's anti-Roman Catholic laws in Great Britain's 13 North American colonies. Also during his reign George III signed legislation abolishing some of the anti-Catholic Laws in Great Britain and Ireland. For example, the Catholic Relief Acts of 1772 and 1774 allowed Roman Catholics to have land leases in Great Britain. A 1793 Irish Parliament bill called Hogart's Act allowed Roman Catholics to vote in Irish elections. But George still blocked a proposal in 1800 by the British Parliament to allow Catholics to sit in Parliament.
