-<em> Both had similar geographical settings;</em>

- <em>Both began with settlements in city-states in close proximity;</em>
The Greeks began and ended (by the Macedonians conquering them) as city-states, never managing to create a unified country or empire. The Romans, on the other hand, started in a city-state model, but expanded and became one huge unified empire.

Since both were surrounded by sea, they were concerned with building a naval power. The Greeks were more into it, as they had multiple conflicts on sea, while the Romans had a very powerful navy, but rarely came to use it.
