What would be the earliest possible period for the disintegration of the Ottoman Empire? The Caliphate of Cordoba disintegrated in 1031 which caused many gains for Christian Iberia. Is it possible for that to happen? If the Ottoman Empire disintegrates, would there be a Reconquista-like effect in the Anatolian peninsula? How can an empire be destroyed so early. If it disintegrates, would Anatolia be re-Christianized?
