The Kosalas in Ancient India

Summary

This comprehensive study traces the history of the Kosala kingdom from its earliest mentions in Vedic literature to its later portrayal in the epics and Puranas. The author begins by noting that the Rgveda does not mention Kosala, but later Brahmana and Kalpasutra texts identify it as one of the sixteen mahājanapadas or great realms. In the Buddha’s time, Kosala was a prosperous monarchy located in what is today eastern Uttar Pradesh, with its capital at Sravasti. The article reconstructs the lineage of the Ikshvaku dynasty, including legendary rulers like Ikshvaku himself, Harishchandra and Sagara, whose exploits – such as the rescue of his ancestor’s horse and the bringing down of the Ganges – are narrated in epic and puranic lore. The author examines the division of the realm into northern and southern Kosala, the latter corresponding roughly to modern Oudh, and tracks its interactions with neighbouring powers like Videha, Kashi, Magadha and the Paurava dynasty. Kosala’s decline is linked to the rise of Magadha and later to the annexation by the Nanda and Maurya empires. By correlating literary narratives with geographic and archaeological evidence, the article offers a synthetic account of Kosala’s political and cultural significance.
