The island of Delos was both relatively geographically central to the entire Hellenic world, and uninhabited at the time, so it was viewed as neutral territory by, and therefore a good location for, an association of Greek city states.

Athens eventually commandeered the Delian league, using its navy for its own purposes, something that oftentimes aggrieved the smaller city states, but the original site was not in Athens.

Sparta was never the site of the Delian League, although Sparta's role was of great importance.

Sinope was never the site of the Delian League, although Sinope's legacy as a Greek colony conquered by the Persian empire was a prime example of why many Greeks thought a Delian League necessary.

Crete was not the site of the Delian League as it was inhabited, and therefore considered not neutral.

The Delian League was formed in 477 BCE It was an alliance of Greek city-states under the control of Athens that was formed to deter and protect against a Persian invasion of Greece. Over time Athens took more and more control over the league, leading to the formation of the Peloponnesian League by Sparta. Eventually these two alliances would be pitted against each other in the Peloponnesian War.

The Roman Empire started with the city of Rome. Greece was a nation containing multiple city states such as Sparta and Athens, which had risen and fallen before the expanding Romans conquered what remained of Greece and integrated its culture, history, and beliefs.

The Delian League was founded by Athens and more than a hundred other Greek city-states in 477 BCE. Its original purpose was to provide for the mutual protection of Greek city-states against the threat of the Persian Empire. Over the years the Delian League morphed into an extension of Athenian power and hegemony, and a rival Peloponnesian League, led by Sparta, emerged to challenge the authority of Athens.

The Zulu kingdom was a 19th-century state based in South Africa that fought a series of wars with expansionist Boer and British forces primarily during the 1860s.
