Emergency Defense in the Xifan Area of the Ming Dynasty and the Ruins of the Fortress in Taozhou Wei
During the Hongwu period,due to the rebellion of the eighteen ethnic groups of the Xifan,the Ming court set up Taozhou Wei in the area adjacent to Xifan.During the Jiajing period,the intrusion of the Xihai Mongols intensified;hence,the goverment established Lintao General Army defence system in the Wanli period.In Taozhou,during the early Ming Dynasty,the attack on Xifan was adventitious;therefore,forts were built on the various tributaries on the north bank of the Tao River and garrisons were stationed on different passes,which worked as an emergency defense for the dispatch of troops in any incident.After the eastward disturbance of the Xihai Mongols,Taozhou Wei built border walls,fortress piers and other facilities from the southwest of the Tao River,extending to the bank of the Tao River northeast of Taozhou Wei,forming an independent closed-loop de-fense area composed of the Tao River and the border wall.However,after that,the Taozhou Wei Fortress formed a situation of more abandonment than continuation.The improvement of the defense level of Taozhou from the guard post to the military town has not changed the characteristics of regional emergency defense in the Ming Dy-nasty,though the number of forts built is large,it lacks radiation capacity,which has become the key to the poor continuity of the fortress.
