Based on Mahabharata evidence, the kingdom of the Angas roughly corresponded to the districts of Lakhisarai,Begusarai, Bhagalpur, Banka, Purnia, Munger, Katihar and Jamui in Bihar and districts of Deoghar, Godda, and Sahebganj in Jharkhand; later extended to include Malda and Uttar Dinajpur in Bengal.
Sabhaparava of Mahabharata (II.44.9) mentions Anga and Vanga as forming one country.
