Ванланг
Văn Lang ended BC when Shu prince Thục Phán, the ruler of the neighbouring upland Âu Việt tribes, overthrew the last Hùng king in approximately 258 BC. After conquering Văn Lang, Thục Phán united the Lạc Việt tribes with the Âu Việt tribes to form a new kingdom of Âu Lạc. He proclaimed himself An Dương Vương and built his capital and citadel, Cổ Loa Citadel, in the modern-day Dong Anh district of Hanoi.
