Abstract
The study of social security in the Arab countries and what threatens them from ethnic conflicts and conflicts pushes us mainly to search for the origins and causes of these conflicts, especially if we know that the Arab world has distinguished for decades peace and coexistence of its various sects and denominations, which made it an ethnic, religious and even cultural mosaic, which was a title For its cohesion in various chapters of history, however, with the development of societies and the emergence of a trend of belonging and loyalty in the interest of these groups, the Arab world, especially in both Iraq and Sudan, was exposed to many forms of ethnic conflicts that expressed their primary loyalties and demanded recognition of their identity.The most important point raised when talking about ethnic conflict is its link to the issue of national unity and the stability of societies, as these conflicts have threatened community security in Iraq and Sudan, including their political stability, especially since there have been trends and speeches calling for division and spreading discord among the people of one country, by stirring up ethnic exploits exploiting In that instability that these countries know, and in that it calls for disintegration and the resulting threat to the foundations of the Iraqi and Sudanese societal system, whose foundations are based on the grouping of heterogeneous peoples nationally.
