Mongolian is the principal language of the Mongolic language family that originated in the Mongolian Plateau. It is spoken by ethnic Mongols and other closely related Mongolic peoples who are native to modern Mongolia and surrounding parts of East and North Asia. Mongolian is the official language of Mongolia and Inner Mongolia and a recognized language of Xinjiang and Qinghai. The number of speakers across all its dialects may be 6.2 million, including the vast majority of the residents of Mongolia and many of the ethnic Mongol residents of the Inner Mongolia of China. In Mongolia, Khalkha Mongolian is predominant, and is currently written in both Cyrillic and the traditional Mongolian script. In Inner Mongolia, it is dialectally more diverse and written in the traditional Mongolian script. However, Mongols in both countries often use the Latin script for convenience on the Internet.

Mongolia is a landlocked country in East Asia, bordered by Russia to the north and China to the south. The western extremity of Mongolia is only 37 km from Kazakhstan, and this area can resemble a quadripoint when viewed on a map. It covers an area of 1,564,116 square kilometres, with a population of just 3.3 million, making it the world's most sparsely populated sovereign state. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, the Second Turkic Khaganate, the Uyghur Khaganate and others.
