The basic, local organisational unit of Freemasonry is the Lodge. The Lodges are usually supervised and governed at the regional level (usually coterminous with either a state, province, or national border) by a Grand Lodge or Grand Orient. There is no international, worldwide Grand Lodge that supervises all of Freemasonry; each Grand Lodge is independent, and they do not necessarily recognise each other as being legitimate.
Modern Freemasonry broadly consists of two main recognition groups. Regular Freemasonry insists that a volume of scripture is open in a working lodge, that every member profess belief in a Deity, that no women are admitted, and that the discussion of religion and politics is banned. Continental Freemasonry is now the general term for the "liberal" jurisdictions who have removed some, or all, of these restrictions.
