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, or clandestine
The International Order of Mixed Freemasonry Le Droit Humain was founded in France in the late nineteenth century, during a period of strong feminist and women's suffrage campaigning. It was the first Co-Masonic Order, and also the first truly international Masonic Order. Today it has members from over 60 countries worldwide.
French Masonry had long attempted to include women, the Grand Orient de France having allowed Rites of Adoption as early as 1774, by which Lodges could "adopt" sisters, wives and daughters of Freemasons, imparting to them the mysteries of several degrees.
In 1879, following differences among members of the Supreme Council of France, twelve lodges withdrew from it and founded the Grande Loge Symbolique Ecossaise (GLSE). One of these Lodges, Les Libres Penseurs (The Free Thinkers) in Le Pecq, reserved in its charter the right to initiate women as Freemasons, proclaiming the essential equality of man and woman.
On January 14, 1882, Maria Deraismes, a well-known humanitarian, feminist author and lecturer, was initiated into Les Libres Penseurs, after of the lodge withdrew from its Grand Lodge . The Worshipful Master, Bro. Houbron, justified this act as having the highest interests of humanity at heart, and as being a perfectly logical application of the principle of "A Free Mason in a Free Lodge".
In 1890 the Lodge La Jérusalem Écossaise, also of the Grande Loge Symbolique Ecossaise, petitioned other Lodges for the establishment of a new order of Freemasonry that would accept both men and women. This time La Jérusalem Lodge did not propose to initiate women itself, but to create a new order working in parallel. The main proponent of this was Dr. Georges Martin, a French senator, advocate of equal rights for women, and also a member of Les Libres Penseurs.
