Vāsudeva I was a Kushan emperor, 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. He ruled in Northern India and Central Asia, where he minted coins in the city of Balkh. He probably had to deal with the rise of the Sasanians and the first incursions of the Kushano-Sasanians in the northwest of his territory.
The last named inscription of his predecessor, Huvishka, was in the year 60 of the Kanishka era, and the Chinese evidence suggests he was still ruling as late as 229 CE.
