Grand Matriarchy of Callisto

History: Callisto was founded by an exceedingly wealthy cult of ultra-feminists in the year 2122. Fed by feelings of oppresion, these women carved for themselves an order based on what they hoped would be saner, more nurturing humanitarian principles. At first, it started out this way. Men were of course allowed on Callisto, but were of aa non-voting, non-property-holding caste. Those who wished to join the colony were required to pass a rigorous battery of psychological exams. For fifty years, this system created a peaceful, artistic society dedicated to art and science.
In the late 2180's however a movement called the Daughters of Parthenus sought to eliminate the need for men on Callisto. Using advanced cloning techniques, they tried to replace natural reproduction with genetic duplication. At the same time, a group of males, desiring a greater voice in their own destiny created a backed political party dedicated to male suffrage. Neither view was popular with the bulk of Callisto's citizens, and a bitter political struggle took place. The fight was relatively bloodless, and ended when the DoP were shown to have actually begun cloning their own children, in direct violation of both interplanetary and local law. The Daughters of Parthenus were shunned by Callistan society. Followers of the order were cast out and given the Southern Rift Valley to live in. There they have cut themselves off from most outside contact. The Male Suffrage party succeeded in gaining some minor concessions for men, but the vigorousness of the party had lain in its opposition to the DoP. Without a solid enemy to target, the party lost steam.
As for the rest of Callisto. It is a world that has admirably met its charter. Some of the Colonies' most important technological achievements have been accomplished here.
