Answer:
During the Maurya and Gupta empires, the Indian culture and way of life were deeply influenced by Hinduism. Hinduism reinforced a strict social hierarchy called a caste system that made it nearly impossible for people to move outside of their social security.
Hinduism has changed over time because it does not have one founder so people have been able to slightly altered the beliefs. The teachings and principles of most religions do not change, it is the interpretation that changes.
I don't know which specific context you refer to - the Han Chinese have conquered many people.
So I will provide one example - in Taiwan, the aboriginal people were required to have Chinese names in their passports until recently, which means that every person was forced to adopt a Chinese name, and often their original name was dropped, and (over generation) forgotten. This has changed how people self-identify: weakening their indigenous sense of identity.
