The Great Migration

The Great Migration was an event that occured between 2100 and 2500, where many different ethnic groups across the world migrated south after their ancestral homelands became tundra in the wake of the New Ice Age. These huge migrations southwards often displaced or eradicated local populations that already resided in the area, and lead to further displacement, until by 2500, the ethnic map of the world had completely changed, and so did some ethnic groups' way of life.

In Europe
The Great Migration in Europe began around 2150, as the Germans, Swedes, Norwegians, and English migrated out of their ancestral homelands, now frigid tundra, for more fertile and temperate lands. The Germans and Scandinavians mostly migrated into Hungary, Northern Italy, Moldavia and the coast of the Black Sea, while the English moved to France and Northern Spain. This first movement is called the First European Exodus. The second big movement was around 2200, as the native Hungarians, Romanians, Ukranians, French and Catalan peoples began moving to escape these new peoples, thus most of these peoples moved south into what was the Balkans, the Iberian Peninsula and the now fused islands of Corsica and Sardinia. This was further increased by migrations of Poles, Czechs, Slovaks, Lithuanians, and Russians into either the Balkans or the Caucasus Mountains, around the same time. This prompted the native Serbs, Croats, Bosniaks, Montenegrins, Albanians, Macedonians, Georgians, Armenians, Chechynyans, Dagestanis and Bulgars to either move to Greece, Anatolia or join the Germans, Hungarians and Romanians in the steppe. This is called the 2nd European Exodus. The 3rd European Exodus, and the last, is characterized by the Irish, Scottish, Welsh, Cornish and Highlander people claiming the British Isles, the Sapmi colonizing the now deserted Scandinavia and Germany, and the Finns, Karelians, Estonians, Latvians, and Uralic peoples now populating the depopulated Eastern Europe. The fleeing Turks, Greeks, and Italians would later spark the Great Migration in Africa and the Middle East.
