Second Sacred War

After the Five Years' Truce, Sparta embarked on a campaign of truncating "Athens' imperialistic ambitions in Central Greece".

[1] The Second Sacred War (Ancient Greek: ἱερὸς πόλεμος)[1] was a conflict over the occupation of the Temple of Apollo at Delphi.

[3] After the Spartans left, however, an Athenian army led by Pericles took the city and re-installed Phocian rule.

[4] Accepting the writings of the Greek historian Philochorus, a group of historians led by Karl Julius Beloch, Benjamin Dean Meritt, Theodore Wade-Gery and Malcolm Francis McGregor argued that the Spartan ejection of the Phocians occurred in 449 BC, and that the Athenians re-installed them in 447 BC.

[5][6] An alternative view was put forward by historians led by Arnold Wycombe Gomme and Felix Jacoby who rejected Philochorus' chronology.
