Corinthian War
Book 4 narrates events of 395–388 BC, and is primarily concerned with the Corinthian War. Book 4 recalls King Agesilaus' Ionian campaign against Persia of 396–395 BC. During this time, Satrap Pharnabazus bribed Greek states into revolting against Sparta. This eventually led to the Corinthian War, with the states of Athens, Corinth, Argos, and Thebes united against Sparta. This led to the recall of the Spartan king Agesilaus and his army in 394 BC from his campaign against Persia. This period saw the beginning of the Corinthian War, with the Persian Empire siding with Athens against Sparta. The Persian satrap Pharnabazus let the exiled Athenian general Conon lead the Persian navy in a number of battles, including the Battle of Cnidus in 394 BC. Conon then convinced Pharnabazus to allow Athens to keep the Persian fleet and to fund the rebuilding of the long walls at Athens.
