Development

In Mongolia and China the great wall was constructed by nomadic herders in 200 B.C. In the 14th century the Kingdom was at a decline because of an invasion and warfare. Mongolia is the home of the historic Mongols. The issue has gotten worse over time because action is not being taken about the issue so desertification is worsening.

• 200 B.C Great Wall Constructed
