Kosala was the ancient kingdom which consisted of 3 important cities - Ayodhya, Saket and Shravasti. Kosala is also mentioned in the great epic stories like Mahabharata, Ramayan and also in Purana. According to a Jain philosophy, Bhagvati Sutri and Buddhist text Anuguttra Nikaya, Kosala was one of the renowned 16 Mahajanpadas. The other Mahajanpadas included cities of Mahabharat times ie Kuru where Kauravas and Bhishma lived, Panchal where Draupadi belonged, Vatsya the place where Pandavas had hidden in their vanvas, Magadh, etc. The capital of Kosala was Sravasti and this Mahajanapada corresponds roughly with the area with the region of Awadh in present-day Uttar Pradesh.
