Historically, the Mongolian nation was composed of two basic parts. Ancient times were divided into "people on the grassland" and "people in the forest". Later, it was Dongmeng (China and Mongolia) and Simon (called Vara in the Ming Dynasty).

The rise of vara

14 14 years, Ming Taizu's ancestor marched north to the west of Mongolia, and suddenly lost temperature in Hulan (east of Ulaanbaatar, Mongolia) during the war with Wala, and Mahamu was defeated. Arutai in eastern Mongolia sent troops to attack again. Mahamu was defeated again, and he died of grief. Mahamu's son took off his joy and attacked, but the Ming court still named him King Shunning.

1423, the relationship between Arutai in eastern Mongolia and the Ming court deteriorated and was defeated by the Ming army. It broke away from happiness and used the gap of Yinma River (now Krulun River) to break its crowd and capture a large number of horses, camels, cattle, sheep and others. The success of Yinmahe greatly enhanced Tuohuan's political, economic and military strength, and unified the various departments of Wallachia.

1434, sent troops to attack Mu Na Mountain (now Wulashan, Inner Mongolia) Arutai, killing Arutai's father and son, all of which were owned by East and West Mongolia. He wanted to be independent and sweaty, but he was strongly opposed by his subordinates because he was not a descendant of Genghis Khan's "golden family". So, Yong Liyuan became a Khan, let him govern the old headquarters of Arutai and live in Hulunbeier grassland; He also married his daughter, took off his wife, became a teacher himself, lived in Mobei, and directly mastered the political and economic power of Mongolia.

1439, Tuoba died of illness, and Zi also succeeded to the throne first. During his reign, Vara reached its heyday.

Vala controlled the ministries of East Mongolia, and at the same time, he used military conquest, official appointment and governance, marriage and alliance to put beggars such as Keith, Hami, Shazhou, Han Dong, Jinchi and Wuliaha under his own rule. In addition, the ministries of Jurchen are well organized and serve them.

In its heyday, the power reached Korea in the east, Dadu River and Taras River in the west, South Siberia in the north and the Great Wall in the south.
