Karl Marx didn't say much on family but it was his friend Friedrich Engels who established the marxist idea of family. According to him, family is an educating entity which teaches the children to accept the structure of capitalism. It is a system that reinforces the idea of hierarchy. He also sees family as a unit which further pushes the ideology of 'consumption', which is a fundamental trait of capitalism. As we know that according to marxist view, the first order in the society was in the form of 'primitive communism'. At that time there was no family according to marxism, or atleast there was no concept of monogamous family structure, because of lack of concept of property. Later on with the idea of personal property and hoarding tendencies the question of heir to property raised. This question led to developing a system of monogamous marriage as now it was easier to distinguish the successor. Thus family can also be seen as an institution through which the 'property' passes down along generations.....

With the advent of modern communism (the last stage of social evolution, according to Marx) the institution of family will also cease to exist, like other institutions of state, religion and so on.
