An international border is a geographical line that separates two sovereign states, marking the extent of their respective territories, jurisdictions, and national identity.
Borders primarily delineate national sovereignty, control migration, regulate trade, manage security, and define cultural or linguistic divisions between nations.

Challenges include territorial disputes, illegal migration, smuggling, security threats, humanitarian crises, and the management of shared or transboundary resources.
