An ethnic group is a community of people who share a common cultural background, language, or ancestry. These groups often have distinct traditions, customs, and social practices that set them apart from others. Examples of ethnic groups include the Han Chinese, Maasai, and Cherokee. Ethnic groups can play a significant role in shaping individual identities and fostering a sense of belonging. They often celebrate their heritage through festivals, art, and cuisine, which helps preserve their unique cultural narratives. Understanding ethnic groups is essential for promoting diversity and social cohesion in multicultural societies.
