I won't write the entire paragraph for you but the Greeks had a pure democracy that any free man could vote it. This is of course in Athens at the time. The Romans had a republic and dictatorship at two different times. Well, first, Rome had kings, then, it had an Emperor under a dictatorship rule, lastly there is the Roman Republic which allowed people to vote like the Greek Democracy. The biggest differences were the senate as well as the people who were allowed to vote as not every man was.
