Primitive communism is a way of describing the gift economies of hunter-gatherers throughout history, where resources and property hunted or gathered are shared with all members of a group in accordance with individual needs. In political sociology and anthropology, it is also a concept, that describes hunter-gatherer societies as traditionally being based on egalitarian social relations and common ownership. A primary inspiration for both Marx and Engels were Lewis H. 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.

A gift economy or gift culture is a system of exchange where valuables are not sold, but rather given without an explicit agreement for immediate or future rewards. Social norms and customs govern giving a gift in a gift culture; although there is some expectation of reciprocity, gifts are not given in an explicit exchange of goods or services for money, or some other commodity or service. This contrasts with a barter economy or a market economy, where goods and services are primarily explicitly exchanged for value received.
