The ancient country of Loulan appeared more than 2,000 years ago and is also recorded in history. The ancient country of Loulan in history was called "a country with walls" and was one of the 36 countries in the Western Regions at that time. The most prosperous period of Loulan ancient country was when there were 12 tribal villages.
During the Han and Tang dynasties, the ancient country of Loulan became the main traffic artery in the western regions and the transit point of the Silk Road. China's tea, silk, porcelain and other items will be transported to the ancient country of Loulan, and then people here will exchange items with people from the western regions.
Ambassadors and businessmen from all countries will trade in the ancient country of Loulan and stay here. The ancient country of Loulan has such an important geographical position, and the economy is of course very developed and prosperous. Gradually, the ancient country of Loulan has become the most prosperous city and the gathering place of eastern and western civilizations.
However, at that time in the 4th century BC, the once most developed and prosperous ancient city of Loulan mysteriously disappeared at that time, leaving only ruins, covered with yellow sand, and no sight of what had happened.
Later, some archaeologists discovered the remains of an ancient city. After identification, they found that this was the once prosperous ancient country of Loulan. Finally, after being buried by yellow sand 1500 years later, the ancient country of Loulan reappeared. Then, why did Loulan, once a prosperous ancient country, say that it would be gone without it? What did Loulan people experience? Where did Loulan people finally go?
First, foreign invasion of Loulan ancient country.
The first statement that the ancient country of Loulan disappeared was that it was invaded by foreign countries. A large number of documents were unearthed from the site of Loulan ancient country, which recorded a minority named Xianbei, who often attacked and harassed Loulan ancient country.
Therefore, experts speculate that the disappearance of the ancient country of Loulan is because the wealth of Loulan was targeted by foreigners and invaded by Xianbei people, and a huge war took place, which made the ancient country of Loulan disappear in the war.
Second, the plague broke out in Loulan ancient country.
The second theory is that a large-scale plague broke out in the ancient country of Loulan. Archaeologists found many mousetraps in the ruins of Loulan, so experts speculated that the ancient country of Loulan was infested with rats, which led to the outbreak of plague and the people of Loulan were infected with the plague.
With the medical level at that time, it was impossible to treat the plague. Once infected, you have to wait for death, which makes the Loulan people extinct.
Third, the sinister living environment.
Recently, it has also been suggested that the uplift of the Qinghai-Tibet Plateau blocked the warm and humid air currents in the Pacific Ocean and the Indian Ocean, which led to the perennial drought in the ancient country of Loulan, and the Peacock River, the life river of Loulan, was cut off, making it difficult for Loulan to survive without water.
The literature also records the method of Loulan people asking for rain. Bulls were killed and sacrificed, and a large number of trees were cut down, which led to soil erosion and made it more difficult to find water. In desperation, Loulan people can only migrate, but there is no record of where Loulan people migrated in history, and it may be that they merged with other ethnic groups.
