On the morning of 28 October, the Greek population took to the streets, irrespective of political affiliation, shouting 'ohi'. From 1942, it was celebrated as Ohi Day, first mostly among the members of the resistance and after the war by all the Greeks. Oxi Day, also referred to as the “Day of No,” is an important part of modern Greek history celebrated annually. It marks the day when the Greek prime minister rejected an ultimatum given by the Italian dictator Benito Mussolini during World War II.
This ultimatum, which was presented to Metaxas by the Italian ambassador to Greece, Emanuele Grazzi, shortly after 03:00 am on 28 October 1940, who had just come from a party in the Italian embassy in Athens, demanded Greece allow Axis forces to enter Greek territory and occupy certain unspecified "strategic locations" or otherwise face war. In response to Metaxas's refusal, Italian troops stationed in Albania, then an Italian protectorate, attacked the Greek border at 05:30 am—the beginning of Greece's participation in World War II.
