A kingdom in northern Vietnam, founded by a warlord, Thuc Phan, who combined Van Lang, a state he conquered and united it with his kingdom in 258 BC, and called the new state Au Lac - which he then ruled under the name An Duong. Au Lac existed only until 207 BC when it was incorporated by a former Chinese general, Trieu Da, into the kingdom of Nam Viet. The end of Au Lac marks the end of legendary history and the beginning of Vietnamese history, as recorded in Chinese historical annals.
