The Ancient Grand Lodge of England, as it is known today, or The Grand Lodge of the Most Ancient and Honourable Fraternity of Free and Accepted Masons as they described themselves on their warrants, was a rival Grand Lodge to the Premier Grand Lodge of England. It existed from 1751 until 1813 when the United Grand Lodge of England was created from the two Grand Lodges. They are now called the Antients, in contrast to the Moderns, the original Grand Lodge which its critics, notably Laurence Dermott, said had moved away from the ritual of Scotland, Ireland, and now the Antient Grand Lodge. This Grand Lodge was also informally called the Atholl Grand Lodge because the Third and Fourth Dukes of Atholl presided over it as Grand Masters for half of its 62-year existence.

The organisation now known as the Premier Grand Lodge of England was founded on 24 June 1717 as the Grand Lodge of London and Westminster. Originally concerned with the practice of Freemasonry in London and Westminster, it soon became known as the Grand Lodge of England. Because it was the first Masonic Grand Lodge to be created, modern convention now calls it the Premier Grand Lodge of England in order to distinguish it from the Most Ancient and Honourable Society of Free and Accepted Masons according to the Old Constitutions, usually referred to as the Ancient Grand Lodge of England, and the Grand Lodge of All England Meeting at York. It existed until 1813, when it united with the Ancient Grand Lodge of England to create the United Grand Lodge of England.
