 After the reign of Emperor Heraclius and the loss of all of its overseas territories, Byzantine territories were limited to the Balkans and Anatolia, both largely Greek-populated areas.When Byzantium began to recover after a series of conflicts in the 8th century and its territories stabilized, its population began to recover.By the end of the 8th century there were 7,000,000 Byzantines, a figure that climbed to 12,000,000 Byzantines by 1025.
