In 133 BC, Emperor Wudi of China ordered a series of attacks on the Xiongnu from Mongolia. After conquering the Hexi Corridor3, which was on the Silk Road, the Emperor wanted to protect his vast new empire. Therefore, he decided to build a long wall. He sent two million people to do it, but there were too many obstacles4. They faced attacks from enemies and poor health from bad food. In addition, the weather conditions were terrible. The high temperatures5 in summer and freezing storms in winter caused damage to the wall. Some of the builders even joined the Xiongnu army against the Emperor, and by 99 BC, the wall was abandoned.
