The present District Of Mandi was formed with the merger of two princely states Mandi and Suket on 15th April 1948, when the State of Himachal Pradesh came into existence. Ever since the formation of the district, it has not witnessed any changes in it's jurisdiction. According to the Tibetan tradition, Padam Sambhav (750-800 AD), the great Buddhist Patriarch, who was summoned by king Tisong-De-Tsen of Tibet for preaching Buddhism, hailed from Zahor, which represents the country round about Rewalsar. On the basis of this it is concluded that Mandi must have been a great place of Buddhist learning about this time.
