Cultural diffusion refers to the spread of cultural beliefs, values, practices, and customs from one society to another through direct contact, migration, trade, or communication. It is a process by which cultures interact and influence each other, leading to the exchange and integration of cultural elements. Cultural diffusion can occur at both local and global levels, impacting everything from language and food to art, music, and religious practices. Studying cultural diffusion can provide insights into how societies shape and are shaped by their interactions with others, as well as how cultural diversity and identity evolve over time.
