Funny part is so many folks get Greece wrong it actually tells you what major geopolitical influence they have.
Greece comes from the Romans calling them "Graeci" or "Like Graia" because the first greeks they had significant contact with were Graian colonists in Cumae.
But everyone from Turkey to India calls them something along the lines of "Yunan", because that's how the Persians started refering to them, because the major greek city state they first had significant contact with was Ionia.
