Ancient Athensball was an ancient countryball that was credited with inventing every modern form of philosophy, science, art and politics as we know it. Many would admit it as being way more advanced than what Greeceball has become now. He is the most important city-stateball and second capital city of Ancient Greeceball
Athensball was the one to win the war against Persiaball. At that time he had become the de-facto leader of the Greek states. He led the other greek cityballs to victory against Persiaball, although some of the other cities didn't like his leading (like Spartaball).
After he won the Greco-persian War, he continued acting like the "Leader of Ancient Greeceball" which made him disliked by many. After a big conflict with Corinthball and Spartaball (and as we all know, having war with Spartaball isn't the best thing that could happen to you), Thebesball and Macedonball joined. Athensball ultimately lost and it became a client state to Spartaball and to Macedonball later.
