A government defines citizenship through legal frameworks that establish rights, responsibilities, and criteria for membership within a nation. This process often involves documentation, such as birth certificates or naturalization papers, ensuring that individuals meet qualifying criteria, including age, residency, and loyalty to the state. Enforcement of citizenship may be undertaken through mechanisms like immigration control, voter registration, and civic education. Essentially, citizenship encompasses not only legal status but also the relationship between individuals and the state, enabling participation in political processes and the enjoyment of rights associated with being a recognized member of society.
