Nepal’s indigenous people’s social, cultural, and political status is complex and constantly changing. This study aims to investigate how modernization has influenced the lives of native Nepalese people in areas such as culture, politics, education, customary laws, and lifestyles. Using an interpretive research design based on modernization theory, information was gathered from Barghars (Tharu village chiefs) through in-depth interviews and secondary sources. Westernization and globalization have considerably impacted indigenous Nepalese communities, affecting their cultural traditions and battles for land rights. Despite these influences, indigenous communities in Nepal and elsewhere have shown resilience and creativity in preserving their heritage while adapting to modernity. Collaboration between policymakers, researchers, and community leaders can lead to comprehensive strategies that respect indigenous knowledge, protect rights, and promote the growth and well-being of communities.
