The entire history of Europe for the past 4,000 years is of migrations from the East to the West. First the Lusitaninans, Basques, Etruscans, and Belgae, then the Celts (let's include the Gauls in that group), then the Mycenaeans, then the Greeks, then the Romans (who were Latins,), then the Franks, Angles, Saxons, and other Germanic tribes, then the Huns and Slavs. Roughly.
