A large number of ethnicities have inhabited Mongolia since prehistoric times. Most of these people were nomads who, from time to time, formed confederations that rose to prominence. The first of these, the Xiongnu, were brought together to form a confederation by Modun Shanyu in 209 BC.
In 1206, Chinggis Khan (also known as Genghis Khan) founded the Mongol Empire, the largest empire in history. The Mongol Empire’s territory extended from present-day Poland in the west to the Korean peninsula in the east, from Siberia in the north to the Arab peninsula and Vietnam in the south, covering approximately 33 million square kilometers. In 1227, after Chinggis Khan’s death, the Mongol Empire was subdivided into four kingdoms. In 1260, Chinggis Khan’s grandson, Kublai Khan, ascended the throne of one of the four kingdoms that encompassed present-day Mongolia and China. In 1271, Kublai Khan formally established the Yuan Dynasty. The Yuan Dynasty was the first foreign dynasty to rule all of China until it was overthrown by the Chinese Ming Dynasty in 1368.
The Mongol court returned to its native land, however, centuries of internal conflict, expansion and contraction brought them fall into Manchu Qing dynasty. They conquered Inner Mongolia in 1636. Outer Mongolia was submitted in 1691. For the next two hundred years Mongolia was ruled by the Qing Dynasty until 1911. Mongolia declared its independence in 1911 under the Bogd Khan, the spiritual leader of Mongolia’s Tibetan Buddhism. However, the Chinese government still considered “Outer Mongolia” as part of it and invaded the country in 1919.
In 1921, People’s Revolution won in Mongolia with the help of the Russian Red Army and thus Mongolia became the second socialist country in the world. After Bogd Khan’s death in 1924, the Mongolian People’s Republic was proclaimed and the first Constitution was adopted.
Mongolia was under a Soviet-dominated Communist regime for almost 70 years, from 1921 to 1990. In the fall of 1989 and the spring of 1990, new currents of political thought began to emerge in Mongolia, inspired by the glasnost and perestroika in the Soviet Union and the collapse of the Communist regimes in Eastern Europe. In March 1990, a democratic revolution that started with hunger strikes to overthrow the Government led to the peaceful renouncement of communism. Mongolia’s renouncement of communism led to a multi-party system, a new constitution and a transition to a market economy.
