The Vamsas and their country.
It lay to the south of Kosala, and its capital was Kosambí (E.g., J.iv.28) on the Yamuná. Udena, son of Parantapa, also called Vamsarájá (E.g., J.iv.370,390), was its king in the time of the Buddha.
Avanti lay to the south of the Vamsa country. The Vamsá were also called Vatsá (Bud. India, 3, 27; Mtu.i.34). The country formed one of the sixteen Mahájanapadá.
The district of Bhagga, in which was Sumsumáragiri, seems to have been subject to the Vamsá in the Buddha's time, for we find Udena's son, Bodhi, living there (J.iii.157, also Mahábhárata ii.30, 10f). In nominal lists (E.g., D.ii.200) the Vamsá, are generally mentioned with the Cetí.
