Inner Asian Mountain Corridor

The Inner Asian Mountain Corridor (IAMC) was an ancient exchange route in Inner Asia, ranging from the Altai Mountains in Central Asia to the Hindu Kush in South Asia (present-day Afghanistan and northern Pakistan), which took shape in the 3rd millennium BCE. The expansion of the Indo-European Andronovo culture towards the Bactria-Margiana Culture in the second millennium BCE took place along the IAMC, giving way to the Indo-Aryan migration into the Indian subcontinent.
