Abstract

This paper addresses the history of Bezant and the important role allied Arab Tribes had played with it. Those tribes were represented by Lakham, Gutham and Kaleb under the leadership of Chachans that ignated the first conflect between the lamic State and Bezant.
This paper ,also, addresses the relationship between the Roman and Arab Muslims before and after the emissary of prophet Mohammed (peace and prayer upon him). The paper had shown, after collecting many references, that the relationship between the Roman and Muslims was intimate until after Al-Hudaibia’ Agreement. It had shown, moreover, that the military campaigns headed towards Levant in the 5th, 8th and 9th years B.C where prophet Mohammed had led two of them namely; Dwmat Al-Jandal in (5.B-C) and Tobook in (9.B.C) did not aim to conquer the Roman States as Orientalists claim, but a necessary campaign to defend selves and protect the Muslim nation against the Bezant attack when news had come to Al- Madinah that it was imminent.
