The spread of the Assyrian Empire over the entire Fertile Crescent in the second half of the 8th century BC introduced various forms of cooperation between the neighboring nomadic Arabs and the imperial authorities. The geographical conditions and resultant lifestyle of the Arabs facilitated a mutual dependence and delicate equilibrium between themselves and the Assyrian rulers, eager to capitalize on their unprecedented regional might. Henceforth, the Arabs appear as an organic component of the Fertile Crescent history rather than mere desert raiders.
