Where do German people originate from?

Answer 1

Die Bundesrepublik Deutschland (The Federal Republic of Germany)

That's where they live now. The Proto Indo-Europeans began in the Kuban River valley in South Russia. They split in half. The Satems went to live where the Don and Volga Rivers draw together, near Volgograd. The Centums went to live at the mouth of the Danube. Some Centums went to live in Bohemia, and mixed with the Caucasic Iberoi they found living there. These became the Theudi, the very first Germans. But the Theudi were driven out of Bohemia by a Celtic invasion. Moving past the Venedi (Tocharians) that lived in North Germany, the Theudi went to live in Jutland and Scandinavia, where they mixed with Ligurians and Sami. After a while, they came out and seized Germany from the Celts. Then they overran most of Europe, but were absorbed everywhere except Germany.

Answer 2

German people have diverse origins, including various Germanic tribes and later influences from Romans, Celts, and Slavs. The formation of the German nation as we know it today began in medieval times with the consolidation of various Germanic tribes and the Holy Roman Empire.
