Lahaul and Spiti have had a checkered fascinating history and lying on the Himalayan borderlines they have always been the bone of contention for various powers in the Region from the states of Kashmir, Chamba, Kullu, Bushahr, Ladakh, Guge, Tibet, the Chinese and even the Mongols, Baltis and Yarkandis. However little is known of the exact circumstances and the chain of events of History that followed as there are no written records. All the above powerful states / people left some mark or influence on these two adjoining Regions. This is an attempt to piece together their History though for most of the time the History followed its separate course in Lahaul and its own course in Spiti.
