Karl Marx was very much for the rights of women. His theories have led to Marxist feminism that is still going strong today.
Karl Marx believed strongly in equality for all people. He thought that women deserved to be treated the same as man. He believed that social and economic class kept people enslaved. He believed that women were inherently oppressed by capitalism, as they lost out economically by staying home and raising children. This kept them dependent on men to take care of them. He thought communism would solve these problems for women. Marx and his friend,, Friedrich Engles, were lifelong friends and collaborators. Engles wrote about women: "The emancipation of women coming only when they entered the productive workforce. They are able to take part in production on a large social scale and when domestic duties require their attention only to a minor degree." Marx believed that women were kept subjective to their circumstances because of economic and social domination associated with class.
Marx was also quoted as saying "Anyone who knows anything of history knows that great social changes are impossible without feminine upheaval. Social progress can be measured exactly by the social position of the fair sex, the ugly ones included." As you can see Karl Marx thought women had the right to work and be paid fairly for their work. He believed that this was the only way for women to become independent and treated equally.
