Currently the whole history-description of athens is: On my screen this covers 4 of 5 lines. If there is more then 5 lines there is a scrollbar. So don't worry about a too long text. While at it, the Seleucids could have a longer history-description. Currently it's only:

If I can provide a longer summary, I would suggest this: Ancient Athens rose to imperial power in the mid-fifth century BC after the Persian Wars by transforming the Delian League into the Athenian empire. This empire, which dominated the Aegean through tribute and naval supremacy, collapsed in 404 BC at the end of the Peloponnesian War. Athens later regained some influence in the fourth century BC through the Second Athenian League (378–355 BC) and remained a leading city-state. However, it lost its political independence after the defeat at the Battle of Chaeronea in 338 BC, when Philip II of Macedon imposed the League of Corinth upon Greece. Although Athens subsequently attempted to recover its autonomy -most notably during the Lamian War (323–322 BC), the Chremonidean War (267–261 BC), and its revolt in the First Mithridatic War (88–86 BC) - all efforts failed. The city never regained full sovereignty and eventually became a Roman protectorate.
