Strategic Locations: Byzantine territories held several strategically important locations, such as forts, harbors, and trade routes. Conquering these areas allowed the Ottomans to gain control over vital land and sea trade routes, increasing their regional power and influence.
Expansion and Prestige: The Ottoman Empire was engaged in a period of expansion and sought to increase its territory and power. Conquering Byzantine lands enhanced the Ottoman's prestige and elevated their status among other regional powers.
Religious and Political Legitimacy: Controlling the former Byzantine territories, including the city of Constantinople (present-day Istanbul), added historical legitimacy to the Ottoman dynasty. It allowed them to claim the mantle of the Roman Empire and position themselves as the rightful heirs to the region.
Weakening the Byzantine Empire: The ultimate goal was to weaken and eventually collapse the Byzantine Empire, their main regional rival. By conquering Byzantine territories, the Ottomans could reduce their opponent's power, isolate them from allies, and pave the way for their eventual defeat.
