The earliest traces of armed conflict in the territory that constitutes modern Cambodia date to the Iron Age settlement of Phum Snay in north-western Cambodia. Sources on Funan's military structure are rare. Funan represents the oldest known regional political entity, formed by the unification of local principalities. Whether these events must be categorized as conflict remains unclear More information is available for Funan's successor state - Chenla, which has been characterized as distinctly bellicose as it was established by the military subjugation of Funan. Chenla's early aristocrats heralded authority by public display of their noble genealogies carved onto stone stelae all over Indochina. Later, rulers increasingly embraced the concept of divine Hindu kingship.
