evidence: The peoples of Mongolia have a long history under a number of nomadic empires dating back to the Xiongnu in the 4th century B.C., and the name Mongol goes back to at least the 11th century A.D. The most famous Mongol, TEMÜÜJIN (aka Genghis Khan), emerged as the ruler of all Mongols in the early 1200s. By the time of his death in 1227, he had created through conquest a Mongol Empire that extended across much of Eurasia. His descendants, including ÖGÖDEI and KHUBILAI (aka Kublai Khan), continued to conquer Eastern Europe, the Middle East, and the rest of China, where KHUBILAI established the Yuan Dynasty in the 1270s. The Mongols attempted to invade Japan and Java before their empire broke apart in the 14th century. In the 17th century, Mongolia fell under the rule of the Manchus of the Chinese Qing Dynasty. After Manchu rule collapsed in 1911, Mongolia declared independence, finally winning it in 1921 with help from the Soviet Union. Mongolia became a socialist state (the Mongolian People’s Republic) in 1924. Until the collapse of the Soviet Union in 1989, Mongolia was a Soviet satellite state and relied heavily on economic, military, and political assistance from Moscow.
