The autochthon of the region has a unique culture that reflects its long history.
Autochthon is formed from "auto-" (meaning self) and "chthon" (from Greek "chthonios", meaning of the earth or ground). The word refers to someone or something that is native to a particular place, literally meaning 'self-born from the earth'.
Think of 'self' ('auto-') and 'earth' ('chthon') to remember that an autochthon is someone who is native to the land.
