[edit] Events

The island of Aegina and Athens go to war. The island had earned the enmity of Athens by earlier submitting to the Persians. The Spartan King, Leotychides, tries unsuccessfully to arrange a truce in the war.
Athenian Archonship becomes elective by lot from all the citizens, an important milestone in the move towards radical Athenian democracy. There are nine archons and a secretary. Three of the archons have special functions: the basileus, or sovereign; the polemarch (originally a military commander); and the archon eponymous (chief magistrate), who gave his name to the year.
