Siokot was a state in India that preceded the princely state of Mandi, which was founded in 1527. Formerly part of the Kingdom of Suket in the Punjab Hills, the rajput dynasty traditionally goes back to 765 AD. In about 1100, Vijaya Sen had two sons, Sahu Sen who ruled over Suket and Bahu Sen who ruled over Kullu. Bahu Sen's descendants emigrated to Kullu until the tenth descendant, Kabakha Sen was killed by the Raja of Kullu and his son had to flee to Siokot, not very far from the present city of Mandi, Himachal Pradesh, which was founded during Ajbar Sen's rule.
