Problems of the byzantine defence system which were appeared in the war between Arab and Byzantium in the mid-7th century, concerning the byzantine Egypt

There were several problems of the byzantine defence system concerning the byzantine Egypt in the mid-7th century. They are largely divided in two parts. The one is military defence system, the other is psychological defence system. Military defence system was faced with problems in the decrease of number of army, the absence of positiveness of emperor to be at war, struggle of power at the byzantine court, Great Plague(541, 558 and 573/4), absence of the serious invasion of foreign countries for long times, local recruiting, problem of the arrangement of superior soldiers, and the duality of civil system and military system. Psychological defence system was faced with problems in the oppressive measure of the byzantine government against Monophysites who had a lack of confidence to policy of government, and a psychological unrest on the heavy tax which the byzantine government imposed on local economy which was decreasing in the mid-7th century in the area of Egypt. So military defence system and psychological defence system, concerning the byzantine Egypt in the mid-7th century, which were caused by Great Plague and the war between Byzantium and Persia, mean that the wrong policy of the byzantine government on local area caused troubles which made finally to turn the egyptian people to Arab.
