Question

Which empire's rise contributed to the loss of Byzantine territories in the 600s and 700s?

The Roman Empire

The Mongol Empire

The Islamic Caliphates

The Persian Empire

Answer 1

The rise of the Islamic Caliphates contributed significantly to the loss of Byzantine territories in the 600s and 700s. During this period, the Caliphates expanded rapidly, conquering large parts of the Byzantine Empire, including territories in the Levant, North Africa, and later parts of Anatolia. This expansion weakened Byzantine control and influence in these regions.
