Videha was an ancient Indo-Aryan tribe of north-eastern Indian subcontinent whose existence is attested during the Iron Age. The population of Videha, the Vaidehas, were initially organised into a monarchy but later became a gaṇasaṅgha, presently referred to as the Videha Republic, which was part of the larger Vajjika League.
