在前两期,我们简单回顾了一下拜占庭帝国文化和军事教育以及从其中走出来的若干帝王和将军,时间线最终是来到了公元7世纪的中叶。我们关于明君名臣名将的话题还没有说完,但如果要继续谈下去,就要对中世纪的军事形势做一个简单梳理,才能继续之前的话题,所以本期我们插登一篇背景介绍。 In the first two periods, we briefly reviewed the Byzantine Empire culture and military education and the emperors and generals that came out of it. The timeline eventually came to the mid-seventh century. We have not finished talking about the famous Mingchen famous star, but if we want to continue talking about it, we must make a brief review of the military situation in the Middle Ages in order to continue the previous topic. Therefore, we will insert a background introduction in this issue.
