Vatsa

Vatsa or Vamsa (Pali and Ardhamagadhi: Vaccha, literally "calf" ) was one of the sixteen Mahajanapadas (great kingdoms) of Uttarapatha of ancient India mentioned in the Aṅguttara Nikāya.

Location
The territory of Vatsa was located to the south of the Gaṅgā river, and its capital was the city of Kauśāmbī or Kosāmbī, on the Yamunā river and corresponding to the modern-day location of Kosam.

The early period
The Vatsas were a branch of the Kuru dynasty. During the Rig Vedic period, the Kuru Kingdom comprised the area of present day Haryana/ Delhi and the Ganga-Jamuna Doab, till Prayag/ Kaushambi, with its capital at Hastinapura. During the late-Vedic period, Hastinapura was destroyed by floods, and the Kuru King shifted his capital and all his subjects to a newly constructed capital that was called Kosambi or Kaushambi. In the post Vedic period, when Aryavarta consisted of several Mahajanapadas, the Kuru Dynasty was split between Kurus and Vatsas. The Kurus controlled the Haryana/ Delhi/ Upper Doab, while the Vatsas controlled the Lower Doab. Later, The Vatsas were further divided into two branches—One at Mathura, and the other at Kaushambi.

The Puranas state that after the washing away of Hastinapura by the Ganges, the king, the great-great grandson of Janamejaya, abandoned the city and settled in. This is supported by the and the  attributed to. Both of them have described the king Udayana as a scion of the family. The Puranas provide a list of ’s successors which ends with king. Other Puranas state that the Vatsa kingdom was named after a king, Vatsa. The Ramayana and the Mahabharata attribute the credit of founding its capital to a Chedi prince  or.

The Mahabharata and the Harivansa states the close connection between the Vatsas and the Bhargas (Bhaggas).

II married a princess of Videha, who was the mother of Udayana. He also married, a daughter of the Licchavi chieftain. He attacked, the capital of during the rule of.

The wife of Śatānīka and the mother of Udayana was Queen Mṛgāvatī (in Sanskrit) or Migāvatī (in Prakrit). She was the daughter of Chetaka, the leader of Vaishali. It is recorded that she ruled as a regent for her son for some period of time, although sources differ about the specific circumstances. According to the Jain canonical texts, Udayana was still a minor when Śatānīka died, so "the responsibility of governing the kingdom fell on the shoulders of queen Migāvatī ... till her son grew old enough". On the other hand, Bhāsa's Pratijñāyaugandharāyaṇa says that she took "full charge of the administration" while Udayana was held as a prisoner by King Pradyota of Avanti, and "the way in which she discharged her duties excited the admiration of even experienced ministers". Mrigavati, is notable for being one of the earliest known female rulers in Indian history.
