He was the father of the great ruler Nahapana, according to one of the latter's coins. He was preceded by Abhiraka (Aubhirakes), of whom a few coins are known. some scholars identify him with Ysamotika, the father of Chashtana. His coins bear Buddhist symbols, such as the eight-spoked wheel (dharmachakra), or the lion seated on a capital, a representation of a pillar of Ashoka. Bhumaka's coins have been found in the regions of Gujarat, Kathiawad and Malwa.
