What is having people conform with the customs, attitudes etc of an existing group?

Cultural Integration

Explanation:

The definition of "integrate" is "bring (people or groups with particular characteristics or needs) into equal participation in or membership of a social group or institution." The customs and attitudes of an existing group could be described as that group's culture, so it would be called "cultural integration."
