扶南
According to modern scholars drawing primarily on Chinese literary sources, a foreigner named "Huntian" [pinyin: Hùntián] established the Kingdom of Funan around the 1st century CE in the Mekong Delta of southern Vietnam. Archeological evidence shows that extensive human settlement in the region may go back as far as the 4th century BCE. Though treated by Chinese historians as a single unified empire, according to some modern scholars Funan may have been a collection of city-states that sometimes warred with one another and at other times constituted a political unity.
