Anglo-American Freemasonry (Also self-described as Regular Freemasonry) is a term used to describe a loose network of overlapping chains of mutually recognized Grand Lodges that (for the most part) trace their descent from one of “original” British Grand Lodges (the Premier Grand Lodge of England, the Antients Grand Lodge of England, the Grand Lodge of Scotland, and the Grand Lodge of Ireland); with mutual recognition based on adherence to certain core values, rules and membership requirements (known as Landmarks).
