Its seat was originally at Suidezhou (绥德州), with the counties of Mizhi (米脂) and Wubu (吴堡) lying outside its direct control[1](https://zh.wikisource.org/wiki/明史/卷178). \n\n| Key fact | Detail |\n|---|---|\n| Original seat | Suidezhou, with Mizhi and Wubu outside it[1](https://zh.wikisource.org/wiki/明史/卷178) |\n| Formation as a garrison | Early Zhengtong reign, according to modern scholarship[2](https://ming.cnhis.ncnu.edu.tw/wp-content/uploads/2007/10/Pp16.pdf) |\n| Fortified camps | about 30 castles along the border (one study counts 30+)[3](https://www.loc.gov/item/2021666330/) • [4](https://doi.org/10.1080/02529203.2010.503073) |\n| Military farmland | 48,161.83 qing held by the three guards in the 35th year of Wanli (万历三十五年)[5](https://www.dlyj.ac.cn/article/2016/1000-0585/1000-0585-35-4-790.shtml) |\n\n## Founding and history\n\nAccording to a conference paper on the evolution of the northern frontier military command system during the Hongwu and Yongle reigns, the exact date at which Yansui became a formal garrison is disputed. Modern scholarship on the northern defense system holds that Yansui had formed a military garrison by the early Zhengtong reign[2](https://ming.cnhis.ncnu.edu.tw/wp-content/uploads/2007/10/Pp16.pdf). The Kangxi-era *Gazetteer of Yansui Garrison* gives a later sequence: after the Tumu crisis of the 14th year of Zhengtong (正统十四年), when Mongol forces under A Luo Chu and others began raiding, the court ordered the grand defender-in-chief [Wang Zhen](https://www.edgepedia.org/wang-zhen) (王祯, not to be confused with the eunuch Wang Zhen 王振 of the Tumu crisis) to defend Yansui[10](https://www.newton.com.tw/wiki/%E9%99%9D%E8%A5%BF%E6%A6%86%E6%9E%97%E5%9F%8E%E7%89%86/12780551); he pursued the enemy out of the border with 3,000 light cavalry, covering 500 li day and night, and then memorialized to build the city of Yulin (榆林). In the seventh year of Chenghua (成化七年) the regional inspector Wang Rui (王锐) memorialized to establish the [Yulin Guard](https://www.edgepedia.org/yulin-guard)[6](https://www.shidianguji.com/zh/book/HY0145/chapter/1k53qruedr0gr).\n\n## Structure, functions, and personnel\n\nThe garrison's command structure, as recorded in the Kangxi gazetteer, placed a single grand defender-in-chief over three routes of troops, stretching from Huangfuchuan (黄甫川) to Dingbian (定边), with the camps of Yan'an (延安), Yijun (宜君) and others subordinate within[8](https://www.shidianguji.com/book/HY0145/chapter/1k53qr6q30gti). Each route was led by a vice commander-in-chief: the central route's post was created in the mid-Wanli years and stationed at the garrison city (moved to Boluo (波罗) in the tenth year of Shunzhi under the Qing), the eastern route's was also created in the mid-Wanli years at Gushan (孤山) (moved to Shenmu (神木) in the thirteenth year of Shunzhi), and the western route's was created during the Jiajing reign at Dingbian[8](https://www.shidianguji.com/book/HY0145/chapter/1k53qr6q30gti).\n\nThe *History of Ming* records the case of a man long enrolled in the Yansui Garrison as a soldier who, condemned to death for breaking the law, was spared because the commanding officer Chen Hongfan (陈洪范) admired his appearance and petitioned the grand defender-in-chief [Wang Wei](https://www.edgepedia.org/wang-wei) (王威) on his behalf; the man then fled[9](https://zh.wikisource.org/wiki/明史/卷309).\n\n[Land tenure](https://www.edgepedia.org/land-tenure) underpinned the garrison. The two guards of Yansui held very extensive military farmland: the Yan'an Guard bordered Huanqing on the west, and the Suide Guard reached the [Yellow River](https://www.edgepedia.org/yellow-river) on the east, spanning six or seven prefectures and counties[8](https://www.shidianguji.com/book/HY0145/chapter/1k53qr6q30gti). Reclaimable figures show growth through the late sixteenth century: the three guards held 37,717.23 qing of military farmland in the Jiajing period, 39,753.42 qing in the tenth year of Wanli (万历十年), and 48,161.83 qing by the 35th year of Wanli (万历三十五年)[5](https://www.dlyj.ac.cn/article/2016/1000-0585/1000-0585-35-4-790.shtml). The Wanli-era gazetteer records 162,330.3 qing of pasture land across the 36 border castles[5](https://www.dlyj.ac.cn/article/2016/1000-0585/1000-0585-35-4-790.shtml).\n\n## Political influence\n\nThe garrison was embedded in the civilian-directed command system that the Ming developed from the Yongle and Zhengtong reigns onward, in which civil officials (the regional inspector and grand coordinators) controlled the generals; this arrangement has been assessed as having a positive effect on Ming history[2](https://ming.cnhis.ncnu.edu.tw/wp-content/uploads/2007/10/Pp16.pdf). The Yansui regional inspectorate, seated at Yulin, became one of the fixed provincial-level offices of the northwest[7](https://www.daowen.com/lilun/1563544.html).\n\nStrategically, the gazetteer's own assessment was stark: by abandoning [Dongsheng](https://www.edgepedia.org/dongsheng) (东胜) in favor of Yansui, the dynasty was shielding a frontier of over a thousand li with a single face of territory, and could only be thankful that it held[6](https://www.shidianguji.com/zh/book/HY0145/chapter/1k53qruedr0gr). \n\n## Assessment and legacy\n\nThe Great Wall section and fortified camps of Yansui were built in the course of fighting between Mongols and Han, and served for over three hundred years of Ming and Qing rule as centers of politics, economy, and transport, before falling into disuse in the late Qing and Republican periods; most are now ruins[4](https://doi.org/10.1080/02529203.2010.503073). A study of their decline argues that the main reason was that the sites had been chosen purely for defensive value, so that the later incorporation of the frontier into the interior and structural changes in the border economy hastened their abandonment[4](https://doi.org/10.1080/02529203.2010.503073).\n\nThe garrison's agricultural record is debated. One geographical study finds that Ming military reclamation was concentrated inside the \"Great Border\" line and occupied only a low share of the pasture corridor, so it had little effect on the southward shift of the Mu Us sandy land, and that natural causes were probably the fundamental driver of desert change[5](https://www.dlyj.ac.cn/article/2016/1000-0585/1000-0585-35-4-790.shtml). The same study documents the collapse of the system at the Ming-Qing transition: the near-border farmland of the three guards fell to 2,312.361 qing, only 5 percent of the late-Wanli total of 42,555.13 qing, an abandonment rate of 95 percent[5](https://www.dlyj.ac.cn/article/2016/1000-0585/1000-0585-35-4-790.shtml).\n\nSeveral facts remain disputed among sources: whether the garrison dates from the early Zhengtong reign or from later events such as the Jingtai inspectorate; and whether the line held some 30 to 40 fortified camps[2](https://ming.cnhis.ncnu.edu.tw/wp-content/uploads/2007/10/Pp16.pdf) • [7](https://www.daowen.com/lilun/1563544.html) • [6](https://www.shidianguji.com/zh/book/HY0145/chapter/1k53qruedr0gr) • [3](https://www.loc.gov/item/2021666330/) • [4](https://doi.org/10.1080/02529203.2010.503073). \n\n## References\n\n1. 《明史》卷一百七十八, Wikisource transcription. https://zh.wikisource.org/wiki/明史/卷178\n2. 明代洪武永乐时期北部边防军事领导体制的演变 (Ming Studies conference paper). https://ming.cnhis.ncnu.edu.tw/wp-content/uploads/2007/10/Pp16.pdf\n3.
