I still don't rlly understand what it is

From the above website:

"Cultural diffusion is the spread of cultural beliefs and social activities from one group to another. The mixing of world cultures through different ethnicities, religions and nationalities has increased with advanced communication, transportation and technology."

Here's an example. Most people outside of Italy had never heard of pizza until the late 1940s. Italian immigrants brought pizza here spreading their culture to different lands.

Ask some older people how much the United States customs have influenced people in your area. Perhaps TV and the internet have helped this cultural diffusion.

So I am it kinda like free trade or??

Is it kinda like free trade***

Not exactly, although usually this cultural diffusion works both ways. Immigrants adopt some of the customs of their new land, while the natives adopt some of the immigrants' customs.

Cultural diffusion refers to the process through which cultural beliefs, practices, ideas, and technologies spread from one society or group to another. It occurs when different cultures come into contact with each other, either through trade, migration, conquest, or other forms of interaction. Essentially, it is the spreading and mixing of cultural traits.

To better understand cultural diffusion, you can think of it as the way in which cultural elements, such as language, religion, music, art, fashion, food, or even technology, are shared and adopted by different societies and communities. For example, when a particular style of music or fashion becomes popular worldwide or when a technological innovation developed in one country is adopted and used in other parts of the world, it is an example of cultural diffusion.

One way to observe cultural diffusion is through the examination of historical events and patterns of human migration. As people move from one place to another, they bring their cultural practices with them, sometimes adapting them to the local context. Over time, these cultural practices may merge or influence the existing culture of the new region, giving rise to a unique blend of traditions and customs.

Cultural diffusion plays a significant role in shaping the diversity and evolution of human culture throughout history. It allows for the exchange of ideas, the enrichment of societies, and the promotion of global interconnectedness, where cultures learn from one another, leading to a more interconnected and dynamic world.
