( The N in this name is pronounced like 'n'in 'gun'. When an S is added at the end, it indicates plural number., to mean the people of the land.)
VANGA is the name of the one of the provinces of ancient India. It corresponds to the present Bengal in india and Bangladesh.
As was the custom in Samskritham, country names are given by the people that inhabited it and the name is always in plural.
The king of a country derives his name by the country he ruled. E.g. Paanchaala is the ruler of the country Panchaalam,
Chaidya is the ruler of the country Chedi, Maagadha was the ruler of the country Magadha etc. The word Vangas refers to the land of Vanga as well as its people too.
Vanga is mentioned in Aaranya and Ashvamedha parvas as the name of a province .
"After praying to Naaraayana, Nara, Sarasvathi and Vyaasa, then one should read the Jayam."
