Inner Mongolia (Mongolian: s , Öbür Monggol and c Өвөр Монгол, Övör Mongol; Chinese: 内蒙古; pinyin: Nèi Měnggǔ, but officially romanized to Nei Mongol) is an autonomous region of the People's Republic of China, located in the northern region of the country. Inner Mongolia shares an international border with the countries of Mongolia and the Russian Federation. Its capital is Hohhot and the largest city is Baotou.

Inner Mongolia Autonomous Region was established in 1947 on the area of former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei and Xing'an along with the northern parts of Gansu and Ningxia. It is the third-largest subdivision of China spanning about 1,200,000 km² (463,000 sq mi) or 12% of China's total land area. It has a population of about 24 million as of 2004. The majority of the population in the region are Han Chinese, with a substantial Mongol minority. The official languages are Chinese and Mongolian, the latter written in the Mongolian script, as opposed to the Mongolian Cyrillic alphabet used in the state of Mongolia.

Mongolia ⁱ/mɒŋˈɡoʊliə/ (Mongolian:  Монгол улс (help·info), literally Mongol country/state) is a landlocked country in East and Central Asia. It is bordered by Russia to the north and China to the south, east and west. Although Mongolia does not share a border with Kazakhstan, its western-most point is only 38 kilometres (24 mi) from Kazakhstan's eastern tip. 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. The Mongol Empire was founded by Genghis Khan in 1206. After the collapse of the Yuan Dynasty, the Mongols returned to 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, but had to struggle until 1921 to firmly establish de facto independence from the Republic of China, and until 1945 to gain international recognition.
