The Garam Chashma area became important during the Soviet-Afghan War. During the invasion, the Soviets were unable to stop the flow of arms and men back and forth across the Dorah Pass that separates Chitral, in Pakistan, from Badakshan in Afghanistan. The two dialects spoken in the area of Mamalgha Valley and the area of Munjan Valley differed, being the northern and southern dialects. The language has moved to parts of Chitral, after the War in Afghanistan forced the Munji-speaking people to flee to safer areas.
