Engels

• Mode of production

  Society's combination of productive forces e.g. Machinery, human labour tools and raw materials.
• Primitive Communism

  The earliest stage of society was primitive communism. There was no private property and everyone owned the means of production communally. There was no family, instead there was a 'promiscuous horde' (free for all)
• Monogamous nuclear family

  The monogamous nuclear family was brought around when society's wealth began to increase and so did the development of private property.
• Inheritance of property

  The monogamous nuclear family because essential because of the inheritance of property. Men had to be certain of their child's paternity to ensure they were a legitimate heir. Engels referred to this as 'a world historical defeat for women'.
• A world historical defeat for women

  Marxists argue the only way for women to achieve liberation and to escape patriarchal controls is to overthrow capitalism and private ownership.
• Evaluation of Engels

  He ignores family diversities - it's not just about heirs and inheritance of property. His views are very outdated, especially towards women. Women now earn their own money and are no longer regarded as 'glorified prostitutes'.
