Kanishka was the most powerful ruler of the Kushana Empire. The capital of his empire was Purushpura (Peshawar). Under his rule, Kushana Empire extended from Uzbekistan, Tajikistan to Mathura and Kashmir. Kanishka was the successor of Vima Kadphises, as demonstrated by an impressive genealogy of the Kushan kings, known as the Rabatak inscription.
