National identity refers to the sense of belonging and attachment individuals have to their nation or country. This concept encompasses the shared values, traditions, culture, history, language, and symbols that define a nation and its people. Research in this area often focuses on how national identity is constructed, maintained, and expressed, as well as how it influences individual and collective behavior, attitudes, and beliefs. Scholars in this field may examine the role of national identity in shaping political ideologies, ethnic relations, immigration policies, and nationalistic movements. Additionally, research on national identity may explore how globalization, multiculturalism, and other social and political phenomena impact the formation and evolution of national identities.
