The ancient kingdom of Loulan is located in Mongolia, and on the Silk Road, the kingdom of Loulan is regarded as an ancient kingdom in the Western Regions and belongs to the Xiongnu.
In the Western Han Dynasty, it belonged to the Western Regions of the Han Dynasty. The Western Han Dynasty and the Xiongnu have been fighting for wars over the years, and Loulan is located in the middle, so they often look left and right, and are uneasy to be located in the middle of the two countries.
In order to fight for the Western Regions, the Xiongnu wanted to control Loulan, at first surrendered to the Xiongnu and attacked the envoys of the Han Dynasty, and later the Han Dynasty sent troops to attack and capture the king of Loulan, and Loulan returned to the Han Dynasty.
However, it is difficult for Loulan to do, so they adopt a two-sided tendency, one is to pay tribute to the Western Han Dynasty, and the other is pro-Xiongnu, so that the ancient country of Loulan has become a big problem for the Western Han Dynasty.
During the reign of Emperor Zhao, he sent envoys to assassinate the king of Loulan, re-established a new king, and changed the name of Loulan to Shanshan. The threat of Loulan no longer exists.
In the 4th century AD, the Northern Wei Dynasty successfully destroyed the Shanshan Kingdom, and from then on, the Shanshan Kingdom (Loulan Kingdom) perished.
The ancient country of Loulan, an important town on the Silk Road, slowly disappeared into the clouds of history.
