Buli (tribe)
Buli was an ancient Indo-Aryan tribe of north-eastern South Asia whose existence is attested during the Iron Age. The population of Buli, the Bulayas, were organised into a [Gaṇasaṅgha|], presently referred to as the Buli Republic.
Location
The territory of the Bulayas was said to be located "near Magadha", and their neighbours were the Brāhmaṇa tribe of Veṭhadīpa-Droṇagrāma.The capital city of the Bulayas was the city of Allakappa and some scholars have attempted to identify this city with modern-day Bettiah and other places in Champaran district however these are considered to be just guesses.
Name
The exact origin of the name of the Buli tribe is unknown, although it might have been derived from the Sanskrit root, meaning to "cause to sink" or "to submerge."The name of the Bulaya capital of Allakappa might have been a compound of the terms, meaning "moist" or "wet," and, meaning "anything made with a definite object in view" or "that which is fit and suitable." The name would thus have meant "suitably damp" or "almost damp."
