The word Bangladesh is derived from the word “Vanga” which was first mentioned in the Hindu scripture Aitareya Aranyaka (composed between 500 BC and 500 AD). Bengal was reputedly first colonized by Prince Vanga, the son of King Bali and Queen Sudeshna of the Lunar dynasty. The roots of the term Vanga may be traced to languages in the neighbouring areas. One school of linguists maintain that the word “Vanga” is derived from the Tibetan word “Bans” which implies “wet and moist”. According to this interpretation, Bangladesh literally refers to a wetland. Another school is of the opinion that the term “Vangla” is derived from Bodo (aborigines of Assam) words “Bang” and “la” which connote “wide plains.” The exact origin of the word Bangla or Bengal is unknown, though it is believed to be derived from the Dravidian-speaking tribe Bang/Banga that settled in the area around the year 1000 BCE. Other accounts speculate that the name is derived from Vanga (bôngo), which came from the Austric word "Bonga" meaning the Sun-god. According to Mahabharata, Purana, Harivamsha Vanga was one of the adopted sons of king Vali who founded the Vanga Kingdom. The Muslim Accounts refer that "Bong", a son of Hind (son of Hām who was a son of Prophet Noah/Nooh) colonized the area for the first time. The earliest reference to "Vangala"(bôngal) has been traced in the Nesari plates (805 AD) of Rashtrakuta Govinda III which speak of Dharmapala as the king of Vangala. Shams-ud-din Ilyas Shah took the title "Shah-e-Bangalah" and united the whole region under one government for the first time.
