When people meet through migration, trade or conquest, cultures change. Diffusion explains how traits travel; this lesson names what happens when they arrive.
Key idea
Acculturation: a group adopts some traits of another culture while keeping its own (learning a new language for work but speaking the home language with family). Assimilation: a group takes on the larger culture so fully that its original culture fades. Syncretism: two cultures blend into something new. Multiculturalism: several cultures live side by side, each keeping its identity.
Why it works
Change happens in degrees. Newcomers usually adopt the traits they need first: language for work and school, sometimes clothing and food. Whether the home culture survives depends on how large and close-knit the group is, whether it keeps ties with the homeland, and how the larger society treats it. Across several generations, many immigrant families in the United States have shifted to English, a classic path toward assimilation; others keep their language for generations.
Worked examples
Worked example: Day of the Dead
Mexico's Day of the Dead combines older Mesoamerican customs of honoring ancestors with the Catholic feasts of All Saints' Day and All Souls' Day. Which process is this?
- Traits from two cultures combined.
- The result is a new, distinct tradition, not one culture replacing the other.
Answer: Syncretism.
Worked example: Three generations
A grandmother speaks only her home language. Her son speaks both languages. His daughter understands only the new country's language and celebrates only its holidays. Describe the change.
- The son shows acculturation: he added the new language and kept the old one.
- The granddaughter shows assimilation: the original culture has largely faded.
Answer: Acculturation in the second generation, assimilation by the third.
Common mistake
Students treat acculturation and assimilation as the same. With acculturation, people keep their own culture while adding new traits; with assimilation, the original culture fades away. And syncretism is neither: it creates something new from both. Ask: is the old culture still there, gone, or blended?
