Iraq and Syria were the bases for two great transnational churches deemed heretical by the Catholic and Orthodox—namely, the Nestorians and Jacobites. Well into the Middle Ages, the Christian strongholds of the Middle East included such currently newsworthy Iraqi cities as Basra, Mosul, and Kirkuk, while Tikrit—hometown of Saddam Hussein—was a thriving Christian center several centuries after the coming of Islam. Nisibis and Jundishapur were legendary centers of learning that kept alive the culture and science of the ancient world, both of the Greco-Romans and of the Persians.
