Lạc Việt
Âu Lạc (Hán tự: 甌貉/ 甌駱/ 甌雒; Chinese pinyin: "Ōu Luò"; Wade–Giles: "Wu1-lo4" Middle Chinese (ZS): *"ʔəu-*lɑk̚" &lt; Old Chinese *"ʔô-râk") was an ancient kingdom that covered parts of modern-day Guangxi and northern Vietnam to Hoành Sơn Range. Founded in 257 BCE, it was a merger of the former states of Nam Cương (Âu Việt) and Văn Lang (Lạc Việt) but succumbed to the state of Nanyue in 180 BCE, which, itself was finally conquered by the Han dynasty. Its capital was in Cổ Loa, roughly 17 kilometers north of present-day Hanoi, in the upper plain north of the Hong River.
