Trans-cultural Diffusion

Trans-cultural Diffusion

In cultural anthropology and cultural geography, cultural diffusion, as first conceptualized by Alfred L. Kroeber in his influential 1940 paper Stimulus Diffusion, or trans-cultural diffusion in later reformulations, is the spread of cultural items—such as ideas, styles, religions, technologies, languages etc.—between individuals, whether within a single culture or from one culture to another. It is distinct from the diffusion of innovations within a single culture.

Diffusion across cultures is a well-attested and also uncontroversial phenomenon. For example, the practice of agriculture is widely believed to have diffused from somewhere in the Middle East to all of Eurasia, less than 10,000 years ago, having been adopted by many pre-existing cultures. Other established examples of diffusion include the spread of the war chariot and iron smelting in ancient times, and the use of cars and Western business suits in the 20th century.
