What is cultural diffusion?

Cultural diffusion refers to the process by which cultural beliefs, practices, and items are spread from one group to another. This can occur through various means such as trade, migration, conquest, or communication. As people from different cultures interact, they share ideas, languages, customs, and technologies, leading to an exchange that enriches the societies involved. This process has been a significant factor in the development and evolution of civilizations throughout history.

In contrast to the other options, the concept of cultural diffusion specifically emphasizes the movement and blending of cultures, rather than their separation or decline. The growth of culture during a war, the decline of cultural practices, and the isolation of cultural groups do not encompass the idea of sharing and spreading cultural elements, which is the key aspect of cultural diffusion.
