The McMahon Line–Indo–China War 1962: Exam-Ready PDF Notes

Why does a line drawn on a map in 1914 still shape India–China tensions today?

These PDF notes unpack the McMahon Line as a strategic, cartographic, and geopolitical construct that continues to define friction in the Eastern Sector. The content explains why the boundary is “on paper more than on ground,” how watershed logic shaped British frontier policy, and why India accepts the line while China rejects it. With maps and watershed explanations, the notes help you visualise how terrain, ridgelines, and river systems translate into operational realities.
