What term refers to the promotion or celebration of cultural diversity within a society?

The term that refers to the promotion or celebration of cultural diversity within a society is multiculturalism. This concept advocates for recognizing, appreciating, and preserving different cultures and their contributions to society. Multiculturalism encourages the coexistence of various cultural practices, beliefs, and values, allowing individuals from diverse backgrounds to express their identities openly and participate equally in societal life.

This approach stands in contrast to assimilation, where minority groups are expected to adopt the dominant culture, often leading to the erosion of their unique cultural traits. Cultural hegemony refers to the dominance of one culture over others and the way it shapes ideology and social norms. Integration implies combining different cultural groups into a cohesive society, but it may not necessarily celebrate or promote the diversity of those cultures. Thus, multiculturalism specifically highlights the value and importance of cultural diversity, making it the most appropriate answer.
