From Wikipedia: “Freemasonry is a fraternal organization that traces its origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of masons and their interaction with authorities and clients. The degrees of freemasonry, retain the three grades of medieval craft guilds, those of Apprentice, journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by craft, or blue lodge Freemasonry. There are additional degrees, which vary with locality and jurisdiction, and are now administered by different bodies than the craft degrees.”
We further define Freemasonry as a system of morality, veiled in allegory, and illustrated through symbols.
The local unit of Freemasonry is the lodge. The lodges are usually supervised and governed at the state level by a Grand Lodge. There is no national, international, or world-wide Grand Lodge that supervises all of Freemasonry. Each Grand Lodge is independent (sovereign), and they do not necessarily recognize each other as being legitimate.
In Texas, there are 2 Grand Lodges and they do recognize each other as legitimate. They are The Most Worshipful Prince Hall Grand Lodge of Texas, and The Grand Lodge Of Texas. In America, there are only 2 recognized Grand Lodges per state. The names of the Prince Hall Grand Lodges follow the same pattern as here in Texas, except in Mississippi and Florida, where they are called the M.W. Stringer Grand Lodge of Mississippi, and the Most Worshipful Union Grand Lodge of Florida.
