Pre-Dynastic era

The area now known as Vietnam has been inhabited since Paleolithic times, and some archaeological sites in Thanh Hoa Province purportedly date back several thousand years. Archaeologists link the beginnings of Vietnamese civilization to the late Neolithic, Early Bronze Age, Phung-nguyen culture, which was centered in Vinh Phuc Province of contemporary Vietnam from about 2000 to 1400 BCE. By about 1200 BCE, the development of wet-rice cultivation and bronze casting in the Ma River and Red River plains led to the development of the Dong Son culture, notable for its elaborate bronze drums. The bronze weapons, tools, and drums of Dongsonian sites show a Southeast Asian influence that indicates an indigenous origin for the bronze-casting technology. Many small, ancient copper mine sites have been found in northern Vietnam. Some of the similarities between the Dong Sonian sites and other Southeast Asian sites include the presence of boat-shaped coffins and burial jars, stilt dwellings, and evidence of the customs of betel-nut-chewing and teeth-blackening.
