الدور التاريخي للمدن الساحلية في المغرب الأوسط بين العصر القديم و الوسيط : إشكالية تراجع النشاط البحري

الملخص EN

Some historians point out that Islamic conquests have contributed to the disintegration of the unity of the Mediterranean world and therefore to the responsibility of the Arto destroy the civilization of Morocco, inherited largely from Romano-Byzantine civilization, including the Belgian historian Henri Perrin in his famous book Muhammad and Charlemagne.

This led to a change in the balance of power within it, the suppression of the European trade movement in the Mediterranean and the cutting off of trade relations between East and West and the transformation of the Mediterranean Sea from a Roman lake to a Arab-Muslim lake, So the European economy became closed, the ancient world collapsed and the Middle Ages began, but Muslim historians were against this theory, and they proved its futility.
