Kosala, sometimes referred to as Uttara Kosala (lit. 'Northern Kosala') was one of the Mahajanapadas of ancient India.^[2][3] It emerged as a small state during the Late Vedic period^[4][5] and became (along with Magadha) one of the earliest states to transition from a lineage-based society to a monarchy.^[6] By the 6^th century BCE, it had consolidated into one of the four great powers of ancient northern India, along with Magadha, Vatsa, and Avanti.^[2][7]

Kosala belonged to the Northern Black Polished Ware culture (c. 700–300 BCE)^[1] and was culturally distinct from the Painted Grey Ware culture of the neighboring Kuru-Panchala region, following independent development toward urbanisation and the use of iron.^[8] The presence of the lineage of Ikshavaku—described as a raja in the Ṛgveda and an ancient hero in the Atharvaveda^[9]—to which Rama, Mahavira, and the Buddha are all thought to have belonged—characterized the Kosalan realm.^[10][11]

One of India's two great epics, Ramayana is set in the "Kosala-Videha" realm in which the Kosalan prince Rama marries the Videhan princess Sita.

After a series of wars with neighbouring kingdoms, it was finally defeated and absorbed into the Magadha kingdom in the 5th century BCE. After the collapse of the Maurya Empire and before the expansion of the Kushan Empire, Kosala was ruled by the Deva dynasty, the Datta dynasty, and the Mitra dynasty.
