Following the Union of the Antients and Moderns Grand Lodges and the formation of the United Grand Lodge of England in 1813, the articles of union stated that there would be three Craft degrees only, including the Royal Arch, excluding the Mark degree. For this reason, while in the rest of the world Mark Masonry became attached to Royal Arch chapters, in England it was actually proscribed from the Union until the 1850s. It was a group of Scottish masons who procured an illegal warrant from Bon Accord Chapter in Aberdeen to set up a Mark lodge in London. An attempt to add Mark Masonry to the approved craft workings was defeated in 1856, and a "Grand Lodge of Mark Master Masons" was created in response.
