Political boundaries are the defined lines that separate different political entities, such as countries, states, or municipalities. These boundaries can be established through various means, including treaties, wars, and negotiations, and they play a crucial role in governance, law enforcement, and resource management. Understanding political boundaries is essential for comprehending global relations and conflicts. For instance, the boundaries between countries like United States and Canada are not just lines on a map; they represent distinct legal jurisdictions and cultural identities that influence trade, immigration, and diplomacy.
