A report on Inner Mongolia, Hebei and Liao dynasty

He was given great responsibility in Hebei, which allowed him to rebel with an army of more than 100,000 troops.

Control over parts of northeast China and Manchuria by the Liao dynasty of the Khitan people also stemmed from this period.

In the year 630, Tang armies captured areas of the Ordos Desert, modern-day Inner Mongolia province, and southern Mongolia from the Turks.

Ögedei offered his nephew Kublai a position in Xingzhou, Hebei.

He adopted as his capital city Kaiping in Inner Mongolia, later renamed Shangdu.

One of his successful projects was to finish the long-stalled official histories of the Liao, Jin, and Song dynasties, which were eventually completed in 1345.

Liaoning is also known in Chinese as "the Golden Triangle" from its shape and strategic location, with the Yellow Sea (Korea Bay and Bohai Sea) in the south, North Korea's North Pyongan and Chagang provinces in the southeast, Jilin to the northeast, Hebei to the southwest, and Inner Mongolia to the northwest.

Eventually, Liaoning was conquered by the Khitan Liao dynasty, followed by the Jurchen Jin dynasty and the Mongol Empire.

During the Liao dynasty, they dominated a vast area of Siberia and Northern China.

The man came from the Tu River (Lao Ha river in modern-day Jilin, Manchuria) and the woman from the Huang River (modern day Xar Moron river in Inner Mongolia).

The Tang Empress, in what scholars consider a major strategic error, formed an ill-fated alliance with the Turkic leader Qapaghan Qaghan to punish the Khitan for raiding Hebei province.

It usually corresponds specifically to the three provinces east of the Greater Khingan Range, namely Liaoning, Jilin, and Heilongjiang, but historically is meant to also encompass the four easternmost prefectures of Inner Mongolia west of the Greater Khingan.

Historically, the area was also known as Liaoyang (from its capital at Liaoyang) under the Yuan; as Nurgan (from its capital at Tyr) under the Ming dynasty; and as Guanwai or Guandong, meaning "Lands beyond" or "Lands East of the Pass" in reference to the strategic Shanhai Pass between Hebei and Liaoning.

The region came under the rule of various states throughout history, including Yan, Jizi Chaoxian, Weiman Chaoxian, Fuyu, Western Han, Gaogouli, Xin dynasty, Eastern Han, Gongsun Yan, Cao Wei, Western Jin, Former Yan, Former Qin, Later Yan, Tang dynasty, Wu Zhou, Bohai, Liao dynasty, Jin dynasty, Eastern Liao, Later Liao, Eastern Xia, Mongol Empire, Yuan dynasty, Northern Yuan, Ming dynasty, Qing dynasty, and Republic of China.

Rehe was once at the core of the Khitan-led Liao Dynasty.

In 1955, the administration of the People's Republic of China divided the area between Hebei province, Liaoning Province, Tianjin Municipality, and the Inner Mongolia Autonomous Region.

Nevertheless, its built-up area, the third largest in China after Guangzhou and Shanghai, is slightly bigger, including three districts in Hebei (Sanhe, Dachang Hui and Zhuozhou) being conurbated but with Miyun and Pinggu Districts in Beijing not agglomerated yet.

In 938, after the fall of the Tang, the Later Jin ceded the frontier territory including what is now Beijing to the Khitan Liao dynasty, which treated the city as Nanjing, or the "Southern Capital", one of four secondary capitals to complement its "Supreme Capital" Shangjing (modern Baarin Left Banner in Inner Mongolia).

One of its older Mongolian names was the "Black River", because the river runs clear before it enters the Loess Plateau, but the current name of the river among Inner Mongolians is Ȟatan Gol (, "Queen River").

These accounts show that after the river passed Luoyang, it flowed along the border between Shanxi and Henan Provinces, then continued along the border between Hebei and Shandong before emptying into Bohai Bay near present-day Tianjin.

A similar proposal from the Song engineer Li Chun concerning flooding the lower reaches of the river to protect the central plains from the Khitai was overruled in 1020: the Chanyuan Treaty between the two states had expressly forbidden the Song from establishing new moats or changing river courses.
