Quick questions on Pericles and the Athenian empire: HSC Ancient History

The single most symbolic step was the transfer of the League treasury from the sacred island of Delos to Athens in 454 BC. The traditional justification, reported in the later tradition, was security: after the destruction of a large Athenian and allied fleet supporting an Egyptian revolt against Persia, Delos looked exposed. Whatever the motive, the effect was decisive. The allies' pooled reserve now sat on the Athenian Acropolis, under the eye of the Athenian assembly and its officials, the hellenotamiai.

Alongside coercion, Pericles projected a panhellenic image. Around 449 BC, according to Plutarch (Pericles 17), he proposed a Congress Decree inviting all Greek states to a conference at Athens on rebuilding the temples destroyed by Persia and securing the seas; Sparta's bloc refused to attend, and the plan collapsed. Its historicity rests entirely on Plutarch writing over five centuries later, so it is itself a case study in thin evidence. In 444/443 BC Pericles helped found the colony of Thurii in southern Italy, drawing settlers from across the Greek world, a project that could be read either as genuine panhellenic leadership or as an extension of Athenian influence dressed in panhellenic clothes.
