History of Mongolia in the context of "Beijing"

East Asia is a geocultural region of Asia. It includes China, Japan, Mongolia, North Korea, South Korea, and Taiwan, plus two special administrative regions of China, Hong Kong and Macau. The economies of China, Japan, South Korea, and Taiwan are among the world's largest and most prosperous. East Asia borders North Asia to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To its east is the Pacific Ocean.

East Asia, especially Chinese civilization, is regarded as one of the earliest cradles of civilization. Other ancient civilizations in East Asia that still exist as independent countries in the present day include the Japanese, Korean, and Mongolian civilizations. Various other civilizations existed as independent polities in East Asia in the past but have since been absorbed into neighbouring civilizations in the present day, such as Tibet, Manchuria, and Ryukyu (Okinawa), among many others. Taiwan has a relatively young history in the region after the prehistoric era; originally, it was a major site of Austronesian civilisation prior to colonisation by European colonial powers and China from the 17th century onward. For thousands of years, China was the leading civilization in the region, exerting influence on its neighbours. Historically, societies in East Asia have fallen within the Chinese sphere of influence, and East Asian vocabularies and scripts are often derived from Classical Chinese and Chinese script. The Chinese calendar serves as the root from which many other East Asian calendars are derived.

Mongolian names have undergone a number of changes in the history of Mongolia, both with regard to their meaning and their source languages. In Inner Mongolia, Buryatia and Kalmykia, naming customs are now similar to Mongolia but with some differences.

Subutai (c. 1175–1248) was a Mongol general and the primary military strategist of Genghis Khan and Ögedei Khan. He ultimately directed more than 20 campaigns, during which he conquered more territory than any other commander in history as part of the expansion of the Mongol Empire, the largest contiguous empire in human history. He often gained victory by means of sophisticated strategies and routinely coordinated movements of armies that operated hundreds of kilometers apart from each other. Subutai is regarded as one of the greatest military commanders in history, and the single greatest in Mongolian history. He was instrumental in the conquests of Genghis Khan and Ögedei Khan.
