What is "ultra-tories"

The Ultra-Tories were an Anglican faction of British and Irish politics that appeared in the 1820s in opposition to Catholic emancipation. They were later called the "extreme right wing" of British and Irish politics. They broke away from the governing party in 1829 after the passing of the Catholic Relief Act 1829. Many of those labelled Ultra-Tory rejected the label and saw themselves as upholders of the Whig Revolution settlement of 1689. The Ultras were defending "a doctrine essentially similar to that which ministerial Whigs had held since the days of Burnet, Wake, Gibson and Potter".
