Arabian and Islamic expansion
In the 6th century Quraysh—the noble and holy house of the confederation of the Hejaz controlling the sacred enclave (ḥaram) of Mecca—contrived a chain of agreements with the northern and southern tribes that opened the highways of Arabia to commerce. Under Quraysh aegis, caravans moved freely from the southern Yemen coast to Mecca and thence northward to Byzantium or eastward to Iraq. Another agreement made trade with Axum (in what is now Ethiopia) and the African coast secure, as was also the Arabian coastal sea route. Furthermore, members of the Quraysh house of ʿAbd Manāf concluded pacts with Byzantium, Persia, and rulers of Yemen and Ethiopia, promoting commerce outside Arabia. The ʿAbd Manāf house could effect such agreements because of Quraysh’s superior position with the tribes. Quraysh had some sanctity as lords of the Meccan temple (the Kaʿbah) and were themselves known as the Protected Neighbours of Allah; the tribes on pilgrimage to Mecca were called the Guests of Allah.
In its ḥaram Quraysh was secure from attack; it arbitrated in tribal disputes, attaining thereby at least a local preeminence and seemingly a kind of loose hegemony over many Arabian tribes. Temple privileges held by Quṣayy, who established the rule of Quraysh, passed to his posterity, the ʿAbd Manāf house of which collected the tax to feed the pilgrims. The Kaʿbah, through the additions of other cults, developed into a pantheon, the cult of other gods perhaps being linked with political agreements between Quraysh—worshipers of Allah—and the tribes.
