Le Droit Humain is also active in the UK since 26 september 1902 when Annie Besant founded the lodge Human Duty no.6 in London. The British federation currently has 16 lodges.
The British Federation follows the Order of International Co-Freemasonry – Le Droit Humain – in that all members work the Antient and Accepted Scottish Rite and some side degrees of the York Rite. As well as Craft Lodges, the British Federation has also Mark Lodges, Royal Ark Mariner Lodges, Holy Royal Arch Chapters, Rose Croix Chapters, Knight Templar, Knight Kadosh, the 31st degree, the Consistory of the 32nd degree and Grand Council of the 33rd degree all of which are worked Ceremonially. International Co-Freemasonry – Le Droit Humain – is governed by the Supreme Council of the 33rd degree, from Paris.

Rite of Memphis-Misraïm is a combination of the Rite of Misraïm that was founded by Cagliostro in 1738 and the Rite of Memphis that was founded by Jacques Etienne Marconis de Nègre in 1838. In 1889 General Garibaldi combined the two the Rite of Memphis-Misraïm.
Nowadays there is an international organisation working in Argentina, Brazil, Chile, Spain, France, Martinique, Mauritius, New Caledonia, Scandinavia, Switzerland, Uruguay, USA, England, Venezuela.
There are other organsations with similar names.
The website does not say that members have to be master Masons in another lodge, so it does not appear to be a system of side/higher degrees. On the other hand, the website does not say anything about the “blue” grades of Entered Apprentice, Fellowcraft and Master Mason, so I am not 100% sure.
What the website also does not state specifically, is that Memphis-Misraïm lodges are mixed. It does say however under “conditions for admission” that: “You must have been questioned by several Brothers or sisters” (my emphasis). Cagliostro wanted to admit women, so it sounds like this tradition is still followed.
Grand Orient de France was founded in 1773. About a century later they got issues with “regular” Grand Lodges when the GOdF dropped the requirement for the belief in something Divine. The GOdF lost its regularity, but not its popularity. What is less known, is that in 2010 the GOdF decided to allow lodges to initiate women. Since then quite a few lodges have voted for this possibility, but not a whole lot initiated any women. According to the GOdF 1.319 women were initiated in 2013. That is not a whole lot against 49.000 members, but on a positive side, there are no less than 1.200 lodges that possibly initiate women; worldwide that is. There are two lodges in the UK, Loge Hiram and the Freedom of Conscience Lodge, both in London. Because both websites did not work when I tried, I do not know if these are a mixed gender lodges.

The Order Of Women Freemasons was founded in 1908 as The Honourable Fraternity of Antient Masonry split off of Le Droit Humain. The order was initially mixed, but in the 1920’ies decided to become a women-only organisation which was only made official in 1935. In 1958 the name was changed to “The Honourable Fraternity of Antient Masonry, the order of women Freemasons” to avoid confusion with the only women-only order with a similar name (see below).
The order has over 40 lodges in the UK and is also present in Australia, Canada, South Africa, Spain and Zimbabwe.
