'Kosala' (
Sanskrit: कोशल) was an ancient
Indian
Aryan kingdom, corresponding roughly in area with the region of
Oudh. In sixth century BCE, Kosala formed one of the sixteen powerful realms of India (
Mahajanapadas) of Buddhist traditions, and its cultural and political strength earned it the status of
great power.
Shravasti was the capital of Kosala Kingdom between 6th century BC to 6th century AD. However, it was later weakened by a series of wars with the neighboring kingdom of
Magadha and, in the 4th century BC, was finally absorbed by it.
Kosala was the setting of much
Sanskrit epic literature including the
Ramayana, being ruled by the
Raghuvamsa (Dynasty of
Raghu) the family from which
Rama hails.
Buddha and
Mahavira, founder of
Jainism, taught in the kingdom. The King of Kosala was named King
Pasenadi, and who was a follower of Buddha.
