Co-Freemasonry is a form of Freemasonry which admits both men and women. It began in France in the 1890s with the forming of Le Droit Humain, and is now an international movement represented by several Co-Freemasonic administrations throughout the world. Most male-only Masonic Lodges do not recognise Co-Freemasonry, holding it to be irregular.
