Lạc Việt
The Dong Son culture or the Lạc Việt culture (named for Đông Sơn, a village in Thanh Hóa, Vietnam) was a Bronze Age culture in ancient Vietnam centred at the Red River Valley of northern Vietnam from 1000 BC until the first century AD. Vietnamese historians attribute the culture to the states of Văn Lang and Âu Lạc. Its influence spread to other parts of Southeast Asia, including Maritime Southeast Asia, from about 1000 BC to 1 BC.
