The fall of Constantinople and the rise of the West

The Renaissance era in Western Europe was marked by a flourishing of economic and cultural life that gave rise to numerous discoveries and inventions. This paper studies the role played by Greek migrants in this process. Using a newly constructed dataset on Greek migrants in Europe after the fall of Constantinople in 1453, I show that a Greek presence in the second half of the fifteenth century increased city growth in the sixteenth century. In terms of mechanisms, I find that a Greek presence increased the available knowledge stock in astronomy, mathematics, and medicine - fields in which ancient Greek and Byzantine scholars were especially advanced. Finally, I document an increase in upper-tail human capital and inventions in these cities. In this way, the findings illustrate the important role of Greek migrants in disseminating scientific knowledge in early modern Europe and show their positive impact on city growth during that time.
