The word 'barbarian' comes from the Greek word 'Βάρβαρος' (pronounced 'varvaros') people couldn't understand what others were saying, and every word sounded like 'βαρ βαρ' (pronc: 'var var'), thus βάρβαρος. They thought that everyone else was a barbarian. For instance, this also happened in ancient Greece.

I think a lot of ancient civilizations believed that they were the center of the world.


The idea of the Wall was inspired Hadrian's Wall, but resembles a lot the Great Wall of China.
