Jurisdictions
Grand Lodge jurisdictions are typically based on areas of civil government, with a separate Grand Lodge governing Masonic lodges within a particular national or state boundary. Each Grand Lodge functions independently of any other Grand Lodge, setting its own rules and rituals, and determining which other Grand Lodges to recognize. When two Grand Lodges recognize each other they are said to be "in Amity". "Amity" means that the two Grand Lodges recognize each other as being legitimate, and may allow Masons under one Grand Lodge to visit lodges of the other. A Grand Lodge that is not "in amity with" (or recognised by) another Grand Lodge will not permit its members to visit Lodges in the second Grand Lodge's jurisdiction, or vice versa. The cause of a lack of amity is usually due to a perceived or actual violation of one of the Landmarks of Freemasonry.
Furthermore, with some exceptions, especially regarding US Grand Lodges' recognition of Grand Lodges in South America, any Grand Lodge not recognised by the United Grand Lodge of England (UGLE) is also not recognised by any Grand Lodge in amity with UGLE. The largest Grand Orient in the Continental Masonic form is the Grand Orient de France.
While the United Grand Lodge of England, the Grand Lodge of Ireland and the Grand Lodge of Scotland each govern Freemasonry within their respective countries and overseas provinces, Continental European countries typically have more than one Grand Lodge per country. Historically, the United States had recognised one Grand Lodge per state, independent of the Grand Lodge of any other state. Today, most have two: a "mainstream" Grand Lodge and a Prince Hall Grand Lodge. All of the "mainstream" Grand Lodges in the United States of America are recognised by each other, and most recognise each other's Prince Hall counterparts.
Prince Hall Masonry, which was formed while Masonry in the United States was effectively segregated, has a predominantly black membership. Various philosophical and technical reasons historically prevented US "mainstream" Grand Lodges from recognising or acknowledging Prince Hall Grand Lodges as regular bodies operating in accordance with the Landmarks of Freemasonry. Originally having one Grand Lodge for the whole United States, separate Prince Hall Grand Lodges now operate in most US states and jurisdictions. Many PHGLs also sponsor and govern Prince Hall Lodges abroad, principally on or near US military bases. Since the early 1990s onward, most, but not all, US Grand Lodges and Prince Hall Grand Lodges began to extend mutual recognition and promote visitations and fellowship between their members.
