==== Kingdom of Âu Lạc and Nanyue ====
In around third century BC, [[An Dương Vương]] established the capital of [[Âu Lạc]] north of present-day Hanoi, where a fortified citadel is constructed, known to history as [[Cổ Loa]],{{sfn|Taylor|2013|p=14}} the first political center of the Vietnamese civilization pre-Sinitic era,{{sfn|Miksic|Yian|2016|p=111}} with an outer embankment covering 600 [[hectares]]. In 179 BC, the Âu Lạc Kingdom was annexed by [[Nanyue]], which ushered in more than a thousand years of Chinese domination. Zhao Tuo subsequently incorporated the regions into his [[Nanyue]] domain, but left the indigenous chiefs in control of the population.{{sfn|Jamieson|1995|p=8}}{{sfn|Brindley|2015|p=93}}{{sfn|Buttinger|1958|p=92}} For the first time, the region formed part of a polity headed by a Chinese ruler.{{sfn|Kiernan|2019|p=69}}
