Vietnamese civilization traces to the Lac Viet — one of the ancient "Hundred Yue" (Bai Yue) peoples. Legend says the Vietnamese descend from Lac Long Quan (Dragon Lord) and Au Co (a mountain fairy). Their union produced 100 eggs hatching into 100 sons — half went to the sea, half to the mountains — encoding Vietnam's dual lowland-highland heritage.

The Dong Son culture (700–1 CE) produced the iconic Dong Son bronze drums — decorated with geometric patterns and ceremonial scenes, among the finest bronze artifacts of the ancient world. These drums were used in rain rituals and as chiefly symbols across Southeast Asia.

Around 258 BCE, An Duong Vuong conquered Van Lang and established Au Lac, with its capital at Co Loa (Snail Citadel) — a spiral fortification near modern Hanoi still partially visible today.

The legendary Hong Bang Dynasty and the Hung Kings ruled the kingdom of Van Lang — the first Vietnamese state. Although largely mythical, archaeological evidence confirms sophisticated Bronze Age settlement in the Red River Delta by 2000 BCE.
