The Amphictyonic League was a religious association of Greek tribes that was formed in the times before the Greek city-states existed. The institution was already a particularly old element of Greece by the time the first written records emerge. This league was responsible for civil tasks such as caring for temples. This differed from the Delian League because the Delian League has larger political and military implications. The Delian League was a way in which Greek city-states could remain free from Persia. This was also significantly different than the Near Eastern empires. The empires experienced more interconnection, as well as more conflict. Moreover, these empires were generally ruled by a single powerful leader.
Finally, the Greek city-states evolved from separate states to an empire in a slow way. First, each city-state needed to become fully developed and independent in order for everyone to benefit from its presence.The turning point came with the union of two powerful city-states, Athens and Sparta, motivating other city-states to join.
