This day is celebrated throughout Greece, Cyprus and the Greek communities to commemorate the rejection by the Greek dictator Ioannis Metaxas of the ultimatum made by Italian dictator Benito Mussolini on 28th October 1940 and the subsequent Hellenic counterattack against the invading Italian forces. This was the day that the Greeks entered World War 2, and the Greek population that day took to the streets to shout ‘ohi’ which means no.
