Step-by-step explanation:
Several groups of migrants originated just north of the Black Sea in different historical periods. In ancient times, there were migrations of Greek-speaking tribes known as the Dorians after the Trojan War. There were also migrations of groups like the Philistines, Akawasha, Lukka, Shardana, and Tursha during the Late Bronze Age Collapse. In more recent history, instability in Iraq and Syria led to a flood of refugees making their way across the Mediterranean to Europe in 2015. Additionally, during the nineteenth and twentieth centuries, millions of Europeans, including Italians, Jews, and political dissidents, migrated to the United States seeking economic opportunities and to escape persecution.
