History of the Mongols: Invasion of Jin
2020/03/09
Columns of Mongol rider, armed with bow, lance and mace, march through the dark defiles and narrow valleys of the Yan mountains, a confined route for warriors used to the open steppe. Here, the valleys were marked by towns and villages in close proximity, a track for their army to follow, falling upon terrified settlements whose newly collected harvests now fed hungry Mongols. After days of this claustrophobic territory, of surprising and outwitting the garrisons of the forts blocking their path, the mountains suddenly gave way, opening up to the Northern Chinese Plain: low, open country, marked by the great Yellow River, farmland and the capital of the mighty Jin Empire: Zhongdu, modern day Beijing. Northern China was now open to the Mongol horde, and the Mongol conquests were about to begin in earnest. I’m your host David and welcome to Ages of Conquest: a Kings and Generals Podcast. This is the Mongol Conquests.
After returning from the Tangut Kingdom in early 1210, and shortly thereafter disrespecting the envoys of the new Jin Emperor, Wei Shao Wang, Chinggis Khan began his preparations, reviewing his forces and gathering intelligence. Alongside Muslim, Uighur and Ongguds merchants and travelers who brought him information on the Jin, a few Khitan and Chinese officials had already defected to Chinggis, bringing him detailed intelligence and urging an attack. Though still mighty, the 13th century had not been kind to the Jin Dynasty. The 1190s saw a huge flood of the Yellow River, so severe it changed its course; once entering the ocean north of the Shandong peninsula, it now spilled to the south, a drastic shift which displaced entire villages, destroyed cropland and sowed discontent. War with the Song Dynasty from 1206-1208 drained Jin finances, and inflation caused the paper currency of the Jin to be near worthless. The Jin armies, though large and their horsemen still fierce, were past their prime, many having become quite sinicized and lost the biting edge of their grandfathers. The time was as good as any for an assault upon the Altan Khan, the Golden Khan, as the Mongols called the Jin Emperors.
At the start of 1211, the Qarluqs (Kar-luk) of Almaliq (alma-lik) and Qayaliq (kaya-lik) submitted to Chinggis Khan, providing their own Turkic horsemen as auxiliaries. Chinggis positioned his son-in-law, Toquchar, in the west of Mongolia, doubtless with Qarluq forces, to act as a guard against roaming tribes or the Naiman prince Kuchlug (whooch-loog), who usurped power in Qara-Khitai that year. Feeling himself secure and that he had the favour of Eternal Blue Heaven, Chinggis Khan was ready. He marched south early in the spring of 1211 with as many men as he could muster, around 100,000 split into two armies, one commanded by himself, the other by his three oldest sons, Jochi ( Джучи, Зүчи, Züchi) Chagatai (Цагадай) and Ogedai (Өгэдэй). By May 1211, they had crossed the Gobi desert, entering what is now modern Inner Mongolia, the band of steppe between the Gobi and the Yanshan mountains which shield north China.
You may be anticipating the Mongols cinematically bursting through the Great Wall of China, or the popular internet variation wherein the Mongols ‘just went around it.’ But the Great Wall of China as it exists today was built by the Ming Dynasty in the 15th and 16th centuries, well after Chinggis’ invasion. There had been sections of walls built prior, most notably in the Qin and Han dynasties a millenium prior, but the 1000 odd years between the Han and the Ming saw only sporadic building, generally of rammed or stamped earth, which erodes comparatively quickly over time in unmaintained. The Jin Dynasty in the late 12th century had ordered the creation of several dozen kilometres of wall built in Inner Mongolia, a ditch before a rammed earth wall, marked by gates and a few forts. The base of this is still extant, a long, low, grass covered ridge which today
