a dynasty that ruled the ancient Indian kingdom of Magadha from approximately 430 B.C. to 364 B.C., or according to some sources, during the seventh and sixth centuries B.C. The dynasty consisted of two rulers: Saisunaga, who seized power through a coup, and his son Kalasoka, whose murder was arranged by Mahapadma Nanda.
Under the Saisunaga dynasty, the Magadhan state grew by subjugating other states, such as the kingdoms of Avanti and Kasi. The Saisunaga rulers supported Buddhism, and, according to tradition, the Buddhist Second Council met at Vesali during Kalasoka’s reign.
