international boundaries
Lines between nations
International boundaries are the lines that mark where one country's territory ends and another's begins.
These borders may follow natural features like rivers or mountain ranges, or they may be drawn arbitrarily through treaties and agreements.
The international boundary between the United States and Canada is the longest undefended border in the world.
Disputes over international boundaries have sparked countless wars and diplomatic crises throughout history.
