Humoristic cartoon from <i>Puck</i> on the establishment of diplomatic relations between Greece and Persia. In 499 BC, the Persian <a href="https://en.wikipedia.org/wiki/Achaemenid_Empire" class="extiw" title="w:Achaemenid Empire">Achaemenid Empire</a> tried unsuccessfully to conquer various ancient Greek city-states. Finally in 449 BC a de facto peace was concluded and the <a href="https://en.wikipedia.org/wiki/Greco-Persian_Wars" class="extiw" title="w:Greco-Persian Wars">Greco-Persian Wars</a> effectively ended. In 1902, <a href="https://en.wikipedia.org/wiki/Mozaffar_ad-Din_Shah" class="extiw" title="w:Mozaffar ad-Din Shah">Mozaffar ad-Din Shah</a> of Persia and <a href="https://en.wikipedia.org/wiki/George_I_of_Greece" class="extiw" title="w:George I of Greece">George I of Greece</a> agreed to de jure recognition and after 2393 years established diplomatic relations. This of course ignores a long history of Greco-Persian interactions thereafter throughout Antiquity, not least the <a href="https://en.wikipedia.org/wiki/Peace_of_Antalcidas" class="extiw" title="w:Peace of Antalcidas">Peace of Antalcidas</a>, the conquests of <a href="https://en.wikipedia.org/wiki/Alexander_the_Great" class="extiw" title="w:Alexander the Great">Alexander the Great</a> and the <a href="https://en.wikipedia.org/wiki/Seleucid_Empire" class="extiw" title="w:Seleucid Empire">Seleucid Empire</a>, or even the long history of the <a href="https://en.wikipedia.org/wiki/Byzantine-Persian_wars" class="extiw" title="w:Byzantine-Persian wars">Byzantine-Persian wars</a>.
