The George Rex Flag was a protest flag used in the Province of New York at the start of the American Revolutionary War. The flag was adopted following the passage of the Quebec Act 1774 whereby French Roman Catholics were granted emancipation and Roman Catholicism adopted as the state church of Quebec. Though it is not known exactly what the design of the flag was, the commonly accepted version consisted of either an altered Red Ensign or Blue Ensign with the words "George III Rex (Latin: King) and the Defender of the Liberties of America. No Popery".
