Vasudeva I (Kushano Bactrian: ΒΑΖΟΔΗΟ "Bazodeo"; Chinese: 波調 Bodiao; fl. 200 CE) was a Kushanemperor, last of the "Great Kushans." Named inscriptions dating from year 64 to 98 of Kanishka's era suggest his reign extended from at least 191 to 232 CE.
The last named inscription of his predecessor, Huvishka, was in the year 60 = 187 CE, and the Chinese evidence suggests he was still ruling as late as 229 CE. He was the last great Kushan emperor, and the end of his rule coincides with the invasion of the Sassanians as far as northwestern India, and the establishment of the Indo-Sassanians or Kushanshahs from around 240 CE.
His name, Vasudeva, is that of the father of Krishna, the popular Hindu God, and he was the first Kushan king to be named after the Indian God. He converted to Hinduism during his reign.[1][2]
In the Chinese historical chronicle Sanguozhi (三國志), he is recorded to have sent tribute to the Chinese emperor Cao Rui of the Wei in 229 CE (3rd year of Taihe 太和), :
"The king of the Da Yuezhi, Bodiao (波調) (Vāsudeva), sent his envoy to present tribute and His Majesty granted him a title of "King of the Da Yuezhi Intimate with Wei (魏)"." (Sanguozhi)
He is the last Kushan ruler to be mentioned in Chinese sources. His rule corresponds to the retreat of Chinese power from Central Asia, and it is thought that Vasudeva may have filled the power vacuum in that area. The great expansion of the Dharmaguptaka Buddhist group in Central Asia during this period has also been related to this event.
