Answer:
Many Greek scholars fled Constantinopl
left Italy exposed to Ottoman attack
Step-by-step explanation:
The Fall of Constantinople directly affected the start of the Renaissance. Many Greek scholars fled Constantinople before and after the fall of the City due to the Ottoman menace. They went to Italy, where they were welcomed.
The fall of the city was to have immense consequences for the Italian Renaissance.
The Fall of Constantinople also changed the geopolitics of the Mediterranean and it left Italy exposed to Ottoman attacks. The end of the Byzantine Empire also contributed to the decline of the great cities of Genoa and Venice.
The negative side of the impact was that the Black Sea trade crashed as the Ottoman Empire essentially started a monopoly for trade. The Fall of Constantinople severely hurt trades in the European region. The Ottoman conquest affected the highly lucrative Italian trade and gradually reduced trade bases in the region.
