Âu Lạc
256 BCE – 207 BCE · Capital: Cổ Loa · 140,776 km²

Âu Lạc (chữ Hán: 甌貉 or 甌駱; pinyin: Ōu Luò; Wade–Giles: Wu1-lo4 Middle Chinese (ZS): *ʔəu-*lɑk̚ < Old Chinese *ʔô-râk) was a supposed polity that covered parts of modern-day Guangxi and northern Vietnam. Founded in 257 BCE by a figure called Thục Phán (King An Dương), it was a merger of Nam Cương (Âu Việt) and Văn Lang (Lạc Việt) but succumbed to the state of Nanyue in 179 BCE, which, itself was finally conquered by the Han dynasty. Other historical sources indicate that it existed from 257 BC to 208 BC or from 208 BC to 179 BC.

Origins and Founding
According to folklore, prior to Chinese domination of northern and north-central Vietnam, the region was ruled by a series of kingdoms called Văn Lang with a hierarchical government, headed by Lạc Kings (Hùng Kings), who were served by Lạc hầu and Lạc tướng. In approximately 257 BCE, Văn Lang was purportedly annexed by the Âu Việt leader Thục Phán, who according to traditional Vietnamese historiography, was either the prince or king of Shu. These Âu Việt people inhabited the southern part of the Zuo River, the drainage basin of You River and the upstream areas of the Lô, Gâm, and Cầu Rivers, according to Vietnamese historian Đào Duy Anh. The leader of the Âu Việt, Thục Phán, overthrew the last Hùng kings, and unified the two kingdoms, establishing the Âu Lạc polity and proclaiming himself King An Dương (An Dương Vương).

Government, Society and Religion
Based on evidence from the historical and archaeological records, Kim (2015) believed that a "highly centralized, overarching state-level society with enduring political institutions and structure" between 300 and 100 BCE was responsible for the construction of the Cổ Loa settlement. Its size and the requisite workforce to construct it implied "a strong military force and significant centralized, state-like control". The number of bronze tools also suggested the existence of centralized production, social stratification, and material monopolization. That roof tiles can only be found at Cổ Loa also indicated that the site was the capital. Surrounding villages and communities seem to have paid taxes to the centralized polity.

Economy and Trade
The economy was characterized by agriculture with wet rice cultivation, draft animals, metal plowshares, axes and other tools, as well as irrigation complexes. The cultivation of irrigated rice may have started in the beginning of the second millennium BCE, evidenced by findings from palynological sequences, while metal tools were regularly used before any significant Sino-Vietic interaction. Chapuis (1995) also suggested the existence of line fishing and some specialization and division of labor.

Northern Vietnam was also a major hub of interregional access and exchange, connected to other area through an extensive extraregional trade network, since well before the first millennium BC, thanks to its strategic location, access to key interaction routes and resources, including proximity to major rivers or the coast and a high distribution of copper, tin, and lead ores.

Decline and Fall
In 204 BCE, in Panyu (now Guangzhou), Zhao Tuo established the kingdom of Nanyue. Taylor (1983) believed that when Nanyue and Âu Lạc co-existed, Âu Lạc temporarily acknowledged Nanyue to show their mutual anti-Han sentiment, and this did not imply that Nanyue exerted any real authority over Âu Lạc. Nanyue's influence over Âu Lạc waned after it normalized relations with the Han dynasty. The army Zhao Tuo had created to oppose the Han was now available to deploy against the Âu Lạc.

The details of the campaign were not authentically recorded. Zhao Tuo's early setbacks and eventual victory against King An Dương were mentioned in Records of the Outer Territory of Jiao Region (交州外域記) and Records of the Taikang Era of the Jin (晉太康記).
