Which form of govement was created by the Athenians?
The answer they are looking for is democracy.
After the reforms of Solon, all male landowners of property
gained the vote, and any such man could be elected into office,
women, slaves, and xenoi (resident foreigners, Greeks, but not
Athenians) could not vote. Practically everything was decided by
some form of election, and it has been estimated that every male
landowner in Athens will have served in the administration at some
point in his life.
