The Kanva dynasty replaced the Sunga dynasty in Magadha, and ruled in the eastern part of India from 75 BCE to 30 BCE. The last ruler of the Sunga dynasty,Devbhooti, was overthrown by Vasudeva of the Kanva dynasty in 75 BC. The Kanva ruler allowed the kings of the Sunga dynasty to continue to rule in obscurity in a corner of their former dominions. Magadha was ruled by four Kanva rulers. Their dynasty was brought to an end by the ruler of the Satavahana Dynasty or 'Andhra bhritya' dynasty in Pratishthan or Paithan in Maharashtra.
