The Hindu Kush mountain range extends 500 miles westward from Pakistan to what country?

This formidable mountain range is a western extension of the massive Himalayan system, forming the rugged spine of Central Asia. While its eastern end begins in northern Pakistan, the range stretches for about 500 miles westward, with the vast majority of its mass and its highest peaks dominating the landscape of Afghanistan. The mountains effectively divide the country into northern and southern provinces and also touch the border of Tajikistan.

The name Hindu Kush itself carries a dark and debated history. In Persian, the name is often translated as "Hindu Killer" or "Slayer of Hindus." One prominent theory suggests the name refers to the perilous conditions of the mountain passes, which caused the deaths of many Hindu slaves who were forcibly transported through the region from ancient India to Central Asia. A less grim theory posits that the name is simply a corruption of "Hindu Koh," meaning the "Mountains of India," which marked the frontier of the subcontinent.

For millennia, the Hindu Kush has been more than just a geographical feature; it has been a historical barrier and a critical crossroads. Famous passes, such as the Khyber Pass on its eastern spur, have served as vital trade and invasion routes for centuries. The range has shaped the flow of empires, from Alexander the Great (Review) to the Silk Road traders, profoundly influencing the culture and history of the entire region.
