What Is Nationality? Legal Bond, Rights, and Identity

Nationality is the legal relationship between an individual and a state, conferring formal membership in a nation. Key aspects:

• Nationhood: Shared history, culture, language, identity.
• Legal Bond: Evidenced by passport/national ID; creates rights/duties (residence, work, vote, consular protection).
• Acquisition: By birth (jus soli/sanguinis), descent, naturalization (residence, language, oath), adoption.
• Dual/Multiple Nationality: Permitted by some states, restricted by others.
• Distinction from Citizenship: Citizenship often implies fuller political rights (e.g., holding office); terms sometimes overlap.
• Loss/Renunciation: Voluntary renunciation or state revocation (fraud, security).
• International Law Role: Determines treaty rights, diplomatic protection, migration status.

Nationality anchors a person's legal standing in the international system.
