This decision did not come suddenly. Back on Independence Day celebrations on 24 August 2014, Poroshenko was quoted as saying:President #Poroshenko proclaimed October 14 the Day of Defender of Ukraine http://t.co/fBblrHyZHZ pic.twitter.com/6m1LIz4foI

“The phrase ‘Defender of the Fatherland’ has ceased to be a mere abstract and ritualistic expression. Now it has acquired a concrete significance… In the rich and varied history of Ukrainian armies, there are countless battles and dates worthy of being elevated to a Day of the Defender of the Fatherland. I repeat: Ukraine will never again commemorate this holiday by following a historical battles calendar of a neighboring country. We will honor defenders of our Fatherland, not a foreign country’s!”

Soviet tradition of Defender of the Fatherland Day

Breaking free of the Soviet legacy
Is changing the day of a holiday really such a big deal? There are many reasons to conclude "yes." Going beyond a black-and-white interpretation of the World War II Although the holiday of February 23 was first celebrated in 1919, its modern celebratory tradition is one that draws heavily on the concept of the "Great Patriotic War," as World War 2 in the period of 1941-1945 on the extents of the USSR was dubbed by Soviet historiographers. Referring to the struggle between the Soviet Union and the Third Reich in 1941-1945, this designation is still dominant in the Russian information space. It serves an important ideological and even mythological purpose, propelling and glorifying the notion of Soviet forces fighting off fascist invaders and perpetuating the idea of a still-existant unity of nations that emerged after the fall of the Soviet Union. It also simplifies the story of World War 2, creating the image of the "good" and "bad," ignoring the collaboration between two totalitarian states embedded in the Molotov-Ribbentrop pact and the struggle for independence that national forces such as the UPA were leading, sandwiched from all sides between enemy forces. Celebrating Defenders of Ukraine on October 14 allows to go beyond the black-and-white painted by Soviet historiography. A continuity back to the 10th century
" The events of the past months have become for us a very real, although undeclared, war. Perhaps it will enter the history books as the 2014 War for the Fatherland – a war against foreign aggression, a war to defend Ukraine, its freedoms, its honor and glory, its peoples, its independence.”
