The Sa Huỳnh culture was a culture in modern-day central and southern Vietnam that flourished between 1000 BC and 200 AD. Archaeological sites from the culture have been discovered from the Mekong Delta to Quang Binh province in central Vietnam. The Sa Huynh people were most likely the predecessors of the Cham people, an Austronesian-speaking people and the founders of the kingdom of Champa (by wikipedia)
