Important International Boundaries (Lines of Separation)

Boundary Line Countries Separated Year / Details
Durand Line Afghanistan – Pakistan 1893 (British India & Afghanistan)
Radcliffe Line India – Pakistan 1947 (Partition line by Sir Cyril Radcliffe)
McMahon Line India – China (Arunachal Pradesh) 1914 (Simla Agreement; China disputes it)
Line of Actual Control (LAC) India – China Not clearly demarcated
Line of Control (LoC) India – Pakistan (J&K) Military control line, post-1947–48 war
Maginot Line France – Germany WWII Defensive Line
Hindenburg Line Germany – Poland Post WWI boundary
38th Parallel North Korea – South Korea Post-Korean War
49th Parallel USA – Canada Longest undefended border
Siegfried Line Germany – France Defensive line (WWII)
  • Trick to Remember:
    • D-R: Durand → Radcliffe → McMahon → LoC → LAC → international lines for India
    • “R” in Radcliffe = Partition of Republics (India–Pakistan)
    • “M” in McMahon = Mountains (India–China Himalayan Line)
