Freemasonry or Masonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients.
Fraternal orders often have "side degrees" or auxiliaries.
There are many organisations and Orders which form part of the widespread fraternity of Freemasonry, each having its own structure and terminology.
A Masonic lodge, often termed a private lodge or constituent lodge, is the basic organisational unit of Freemasonry.
