An international boundary line separates two or more sovereign states.
– Durand Line: Establishes the border between Afghanistan and Pakistan. It is an international boundary.
– Maginot Line: A defensive line of fortifications built by France along its eastern border primarily with Germany. While a military line, it was situated along a major international border and is often discussed in that context.
– 38th Parallel: Serves as the boundary (or armistice line/demarcation line) between North Korea and South Korea. It is a well-recognized international boundary.
– Dresden Line: Dresden is a major city in Germany. There is no recognized international boundary line known as the “Dresden Line”. It might refer to a historical or local feature, but not an international border.
Therefore, the “Dresden Line” is not an international boundary line.
– International boundary: A line separating countries.
– Durand Line: Afghanistan-Pakistan.
– Maginot Line: French defensive line along the German border.
– 38th Parallel: North-South Korea.
– Dresden is a city, not a boundary line.
Other famous boundary lines include the Radcliffe Line (India-Pakistan), McMahon Line (India-China), Oder-Neisse Line (Germany-Poland), and the Mason-Dixon Line (historical boundary in the US). Military defence lines along borders, like the Maginot Line or Siegfried Line, are distinct from officially demarcated political boundaries, but are often discussed in geographical and historical contexts related to international borders.
