Which groups of people live in the Hindu Kush valleys?

The Hindu Kush region is home to a diverse mosaic of peoples, a result of its fragmented topography and complex history. The inhabitants of its various valleys include:1

• Northwestern Slopes: The Vākhān, Sanglīch, and Anjoman valleys are sparsely populated by Pamir or Mountain Tajik, most of whom are Ismāʿīlī Muslims.1
• Central and Western Valleys: These areas are inhabited by Tajik (Sunni Muslims), Uzbek, and Hazāra peoples.1
• Southern Slopes: Indic Gujar nomadic herders seasonally move through these valleys.1
• Southeastern (Pakistan) Side: The population is largely Kohistani, an ethnic group exhibiting cultural unity from Kashmir to Kabul.1
• Chitral and Nūrestān: This area is home to the Kalasha and the Nūrestāni. The Kalasha are notable for practicing a form of polytheism, while the Nūrestānis were forcibly converted to Islam in 1896.1

Additionally, Pashtun nomads range across the western hills and northern high pastures.1
