What is the legacy of ancient greece and rome?

E Rome gave the world the idea of a republic. Rome also adopted from the Greeks the notion that an individual is a citizen in a state rather than the subject of a ruler. Perhaps Rome’s greatest and most lasting legacy was its written legal code and the idea that this code should be applied equally and impartially to all citizens. Rome preserved and added to Greece’s idea of democracy and passed on the early democratic tradition to civilizations that followed.
