Ancient

Relations between the two people date back from antiquity and well before the Persian invasion of Greece. By the late 6th century BC, the Achaemenid Persian Empire was in control over all of Asia Minor (which included many ethnically Greek areas), as well as many of the Greek islands, Thrace, and the kingdom of Macedonia, the latter two which make up large parts of modern-day northern Greece. There is also the report by Strabo of an Athenian delegation to Persia in 432 BC.^[3]

The relations have evolved from sworn rivalry during the Greco-Persian wars to strong cordiality, since Alexander the Great defeated the Persian Empire. Alexander admired Persian culture, and wanted to create a mixture of Greek and Persian culture which would forever bind and commemorate the two peoples.

This legacy of strong cordiality would thus be found back for many more centuries in various parts of the world named as the Greco-Persian culture. A harmonious blend of both Greek and Persian cultural aspects. The Kingdom of Pontus was a prime example of an entity (in Asia Minor) where Iranian and Greek culture, ethnicity, identity, amongst others, mingled.

In May 2022, Iranian soldiers seized two Greek tankers and took the crew hostage at the Persian Gulf. This move was a punitive action after Greek authorities confiscated Iranian oil held on a Russian-operated ship docked at a port in Greece a month ago, due to European Union sanctions against Russia for the 2022 Russian invasion of Ukraine.^[11]

On June 8, 2022, a Greek court overruled an earlier court order that authorized the United States to seize part of an Iranian oil cargo aboard an Iranian-flagged tanker off the Greek coast.^[12]
