A person who is considered to be uncivilised or primitive is known as a barbarian (or savage).
In colloquial or figurative usage, the term "barbarian" can also apply to an individual who is callous, ruthless, and warlike.
The word was used by the Greeks to refer to people who did not speak Greek or practise traditional Greek practises.
Barbarians are mentioned as far back as the Shang Dynasty and the Spring and Autumn Annals in Ancient China.
Due to Sinocentrism, the Emperor were frequently referred to as "Barbarians" or "uncivilised".
Therefore, the barbarians were gruff, illiterate, and strong people—the very antithesis of what the term has come to represent in modern times.
