Mongolia is a landlocked country in East and Central Asia. It borders Russia to the north and the Inner Mongolia region of China to the south, east and west. Ulan Bator, the capital and largest city, is home to about 45% of the population. Mongolia’s political system is a parliamentary republic.
The area of what is now Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the Gökturks and others. In 1206 Genghis Khan founded the Mongol Empire, and his grandson Kublai Khan conquered China to establish the Yuan Dynasty. After the collapse of the Yuan, the Mongols retreated to Mongolia and resumed their earlier pattern of constant internal conflict and occasional raids on the Chinese borderlands. In the 16th and 17th centuries, Mongolia came under the influence of Tibetan Buddhism. At the end of the 17th century, all of Mongolia had been incorporated into the area ruled by the Qing Dynasty. During the collapse of the Qing Dynasty in 1911, Mongolia declared independence.
