The Gauls in turn became a part of the Hellenistic world proper after the 3rd century BC, following the Gallic invasion of the Balkans and their establishment in Galatia in Asia Minor.

French troops also occupied the Ionian Islands during the Napoleonic Wars, paving the way for the first independent Greek state of modern times, the Septinsular Republic.

France also played a leading role in the effort to bring Greece into World War I, involving itself in the "National Schism" on the side of Prime Minister Eleftherios Venizelos.

French troops, working together with the Venizelists confronted against the royalist forces in Athens, and finally, in June 1917, helped depose the Germanophile King Constantine.

The two countries have had a friendly and strategic alliance for decades and are full members of many international organizations, including the UN, the European Union, NATO, WTO and OSCE.

The fact that 3 French Presidents (De Gaulle, Sarkozy and Hollande) have been the unique foreign leaders (along with US Eisenhower and Bush) in the history of modern Greece that have had the honor to address the Greek Parliament is a clear certification of the long live connection between the two nations.

On 12 September 2020, Greek Prime Minister Kyriakos Mitsotakis announced an arms deal with France for the purchase of Dassault Rafale fighter aircraft and FREMM multipurpose frigates, as well as the recruitment of 15,000 additional troops, amid tensions with Turkey in the eastern Mediterranean.

[11] The slogan "Grèce-France-Alliance" (also in Greek: Hellas Gallía Symmachía, Ελλάς Γαλλία Συμμαχία), traces its roots back to the political and diplomatic support aid France provided to Greece and Constantine Karamanlis at the time of the return to democracy in 1974,[12][13] and nowadays is often used to denote the deep historical, cultural and political relations and close diplomatic cooperation between the two countries.
