Question: What caused a large migration of Greek refuges in the 1450s?
Sentence: Instead, after the fall of the Byzantine Empire to the Turks in 1453, which brought a flood of Greek Orthodox refugees to Italy, humanist scholars increasingly turned to the study of Neoplatonism and Hermeticism, hoping to bridge the differences between the Greek and Roman Churches, and even between Christianity itself and the non-Christian world.
Answer in sentence: no
