All Standard reference books agree that the name "Hindu Kush" of the mountain range in Eastern Afganistan means "Hindu Slaughter" or "Hindu Killer". History also reveals that until 1000 A.D. the area of Hindu Kush was a full part of Hindu cradle. More likely, the mountain range was deliberately named as "Hindu Slaughter" by the Moslem conquerors, as a lesson to the future generations of Indians.
The name Hindu Kush is usually applied to the whole of the range separating the basins of the Kabul, and Helmand rivers from that of the Amu Darya (or ancient Oxus), or more specifically, to that part of the range to the northwest of Kabul.
