Why were the straits between the Aegean and the black seas so important to the byzantine?

The straits between the Aegean and Black Seas, particularly the Bosporus Strait, were crucial to the Byzantine Empire for several reasons. They served as a strategic maritime route for trade, allowing the empire to control vital shipping lanes between Europe and Asia. Additionally, the straits provided a natural defense against invasions, as they could monitor and regulate naval traffic. This control over the waterways helped maintain economic stability and military security for the empire.
