When the Egyptian Empire was at its full apogee, in Europe people lived in caves. When China was a great civilization, Europe was the land of matriarchy. After Aurelian retreat in 400 AD, the torrent of migratory people could no longer been held back. Slavs, Bulgarians, Hungarians, Huns, Vandals, Goths, Visigoths, Franks, Wales, Angles and many others, have occupied all Europe.
The formed kingdoms in Europe were mostly formed by barbarians. The ancestors of modern French are Gauls, Goths and Visigoths, the ancestors of Germans are Angles and Saxons etc. The British existed when the Roman conquest was taking place. We know that because the Roman general who won the battle added at his name the appellative Britanicus. That’s why most European peoples were warrior and had colonies: because they are descended from barbarians.
The today’s people of Egypt are different people than those of ancient Egypt and the hieroglyphic writing from the pyramids was deciphered by Champollion during Napoleon’s campaign in Egypt. The oldest known nation that kept its ethnic purity is Jew nation.
Europe triggered the two world wars as well. When I think that I am descendants of an invader (Roman Empire), pigmented with some DNA from migratory people and some local Dacian! When the Roman army conquered Dacia, just few soldiers were Latins, Sabians or have roots in ancient Etruscans. Most of the soldiers were Asian or African mercenary and slaves of the same origin.
