Primitive communism is a way of describing the gift economies of hunter-gatherers throughout history, where resources and property hunted and gathered are shared with all members of a group, in accordance with individual needs. In political sociology and anthropology, it is also a concept often credited to Karl Marx and Friedrich Engels for originating, who wrote that hunter-gatherer societies were traditionally based on egalitarian social relations and common ownership. A primary inspiration for both Marx and Engels were Morgan's descriptions of "communism in living" as practised by the Haudenosaunee of North America. In Marx's model of socioeconomic structures, societies with primitive communism had no hierarchical social class structures or capital accumulation.
