Chandragupta II ascended the throne in the year 56 of Gupta era. In 319, Chandragupta created for himself the title King of Kings (Maharajadhiraja), and he extended his rule westward to Prayaga, in north-central India. Ten years into his rule, Chandragupta lay dying, and he told his son, Samudragupta, to rule the whole world. His son tried. Samudragupta's forty-five years of rule would be described as one vast military campaign.
