In 1751, as the Moderns increasingly alienated unaffiliated lodges, a few (mainly Irish) lodges in London formed the Antient Grand Lodge of England (the "Antients"), which rapidly became an umbrella organisation for unaffiliated lodges in England. Their second secretary, Laurence Dermott, believed the Royal Arch to be the fourth degree. When the two Grand Lodges merged in 1813, Article Two of the Articles of Union agreed that "pure Antient Masonry consists of three Degrees and no more, viz., those of the Entered Apprentice, the Fellow Craft and the Master Mason, including the Supreme Order of the Holy Royal Arch". Grand Chapter remained, but other degrees from this time has to be administered by separate Masonic Bodies.
