Islam is something of an interesting religion. Starting as a syncretic offshoot of Judaism and Christianity that stresses pure monotheism and submission to God, its adherents were able to unite the Arabian peninsula into a single polity, and was even able to win a few key strategic battles against the Roman and Sassanid empires. Ultimately, however, dynastic struggles, theological schisms, and counter attacks by the Persians and Byzantines prevented the Caliphate (as the early Islamic kingdom was called) from being anything more than a regional power. Over the centuries Arab traders and missionaries were able to spread the faith to distant lands, where it had some success but ultimately hasn't been able to establish itself as a majority outside of the Arabian peninsula and some small enclaves in East Africa.
What would need to happen to establish Islam as a major world religion, and what sort of impact would the rise of Islam have on world history. Furthermore, how would Islam itself be shaped by becoming a major world religion, and how would other religion view it and be shaped by it?
