The practice of polytheistic religion dominated in pre-Islamic Arabia until the fourth century.[1] Inscriptions in various scripts used in the Arabian Peninsula including the Nabataean script, Safaitic, and Sabaic attest to the practice of polytheistic cults and idols until the fourth century, whereas material evidence from the fifth century onwards is almost categorically monotheistic.[2] It is in this era that Christianity, Judaism, and other generic forms of monotheism (variously described as "gentile monotheism", "pagan monotheism", "Himyarite monotheism", "Arabian monotheism", "hanifism", "Rahmanism" and so on) become salient among Arab populations.[3] In South Arabia, the ruling class of the Himyarite Kingdom would convert to Judaism (though a more neutral form of monotheism was maintained publicly) and a cessation of polytheistic inscriptions is witnessed. Monotheistic religion would continue as power in this region transitioned to Christian rulers, principally Abraha, in the early sixth century.
