A Comprehensive Compendium of History, Culture, Lifestyle and Tourism of Odisha
When Prataparudra was encamping in the distant South, Hussain Shah was trying to cross the border. A clash between the Odishan army and that of Bengal took place. The upada grant and Velicherla plates of Prataparudradeva testify to the fact.
During the period of Kapilendradeva, his eldest son Hamvira had accompanied him in almost all his expeditions and brought laurel to the former. His claim to the throne was set aside by Kapilendra, perhaps, due to the persuasion of the mother of Purusottama who was a Phula-Vivahi wife (a position between queens and concubines) of Kapilendradeva. Since the legitimate claim of Hamvira to the throne of Odisha was relegated to back-ground, he proceeded to settle his score with Purusottamadeva.
The Madala panji narrates him as an adopted son of Matta Bhanudeva or Bhanudeva IV, the last Ganga king who was childless. On the other hand, the Gangavamsanucharitarn of Vasudeva Ratha describes that Kapilendradeva usurped throne of the Gangas when Bhanudeva IV was fighting in a distant place.
