Inner Mongolia, officially the Inner Mongolia Autonomous Region, is a landlocked and Mongolic autonomous region of the People’s Republic of China. Its border includes most of the length of China’s border with the country of Mongolia. Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos.
The Autonomous Region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing’an, along with the northern parts of Gansu and Ningxia.
Its area makes it the third-largest Chinese administrative subdivision, constituting approximately 1,200,000 km2 (463,000 sq mi) and 12% of China’s total land area. Due to its long span from east to west, Inner Mongolia is geographically divided into eastern and western divisions. The eastern division is often included in Northeastern China (former Manchuria), with major cities include Tongliao, Chifeng, Hailaer, Ulanhot. The western division is included in Northwestern China, with major cities include Baotou, Hohhot.
The majority of the region’s population is Han Chinese, with a sizeable Mongol minority close to 5,000,000 (2019), the largest Mongolian population in the world (bigger than that in the Republic of Mongolia). The official languages are Mandarin and Mongolian, the latter of which is written in the traditional Mongolian script, instead of the Mongolian Cyrillic alphabet, which is used in the state of Mongolia (formerly often described as “Outer Mongolia”).
