Bimbisara

Bimbisara was the son of Bhattiya and ruled Magadha from roughly 543 to 492 BCE (or by another reckoning, 457 to 405 BCE), belonging to the Haryanka dynasty. His annexation of the kingdom of Anga to the east expanded Magadha's reach and set the stage for the later Mauryan Empire. Buddhist tradition remembers him as a great friend and protector of the Buddha; Jain histories call him Shrenika or Seniya and say he frequently visited Mahavira's Samavasarana for answers, even claiming he would become the first tirthankara of a future cosmic age. The 7th-century Chinese monk Xuanzang credited him with building the city of Rajgir. His son Ajatashatru took the throne after him.
