The Saka were the first ancient Turkic tribal alliances at the territory of Kazakhstan. They belonged to Caucasian race. The Saka spoke Eastern Iranian language, they had different relations with China, India, Iran (Persia); the dominating form of religion was ancestor worshipping.so in my opinion they are The descendants of turks.Well maybe his tribe was related to the Gokturks as we all know that they came from the same region.So in a sense it's quite possible that Kanishka was a predecessor of the modern day Turks although there is no definitive proof to support this theory..![]()
