The basic thing is that Gor is a planet away from here, and they have leaders called the Priest Kings. The Priest Kings go out to other planets and steal people, eg: Earth. On Gor, women are subserviant to men in all things. They are either a Free Woman, or they are a slave. There are many, many different kinds of slave (ranging from coin girls--they're basically hookers for their masters--to flute girls--slaves that play music and are more like geisha than prostitutes). A female slave is called kajira and is branded upon her slavery, normally on the upper left thigh.
A Free Woman is allowed more freedom, obviously, but she's still got to remember her "place". If she fails to do so, she'll be beaten to death or collared. She's meant to be chaste, humble, and capable: she should be able to do something, like nurse the wounded or ill, or perhaps become a seamstress.
Men have to go through a series of courage tests to prove themselves to other men. In every area, be it a city or a tribe, there's an Ubar that rules over all of them.
A surprisingly large amount of people try to pracist the aspects of Gor in their own lives, to the extent that they can without breaking the law. Obviously, if a slave doesn't please a man, then he can't exactly break her neck for it, there's no rape, there's no beating to the point of hospitalization, none of that sort of thing. I've found it interesting every since I found out, but I'd never want to practise it myself. Women are viewed as replaceable in Gor, and I'd much rather be snuggled and treasured by my sweetie.
