Ionia rises against the Great King

Via Wikimedia Commons The Greek cities of Ionia throw off Persian rule, and Athens sends ships to their aid.
From the Ionian cities' revolt against the Great King and the burning of Sardis, through Darius's punitive expedition broken on the plain of Marathon, to Xerxes' vast invasion — the doomed stand at Thermopylae, the wooden walls that triumphed at Salamis, and the deliverance at Plataea. Slide across half a century in which a handful of quarrelsome city-states turned back the greatest empire on earth, and Greece found the confidence that would shape its golden age.
