Why is the fall of Constantinople connected with the background of Renaissance and exploration?

Correct answer: It affected eastern trade routes and movement of Greek scholars to Europe

The direct answer is D: it affected eastern trade routes and helped Greek scholars move toward Europe. Constantinople fell to the Ottoman Turks in 1453. It had been an important centre connecting Europe with Asian trade. Ottoman control changed the conditions of some eastern routes, encouraging European powers to search for alternative sea routes. At the same time, Byzantine and Greek-speaking scholars carried manuscripts and knowledge to Italian and other European centres, helping intellectual activity associated with the Renaissance. Option D is correct because it describes these economic and cultural effects. Option A is wrong because the United Nations was founded in 1945. Option B is wrong because the First World War began in 1914. Option C is wrong because American independence was declared in 1776. The event did not single-handedly cause the Renaissance or exploration, but it formed part of their background. Memory cue: 1453 means Constantinople falls; trade routes and learning shift.
