Bhúmanyu means Emperor. Bhúmanyu / Bhoomanyu / Bhuvmanyu was the successor of first emperor of India, Bharata. Emperor Bharata, one of the greatest kings of ancient India, and founder of the eponymous dynasty, had nine sons from three wives. No son was worthy to become the next Emperor, Bhúmanyu was born out of a great sacrifice that Bharata performed for the sage Bharadwaja. Bhúmanyu was adopted by Bharata as his son.
Bhumanyu was made the next emperor. Bhumanyu's lineage is the story of the Mahabharat.
