To this day, New Year's Eve is a bigger deal than Christmas in Russia. That's when the Russian version of Santa — Ded Moroz, or Father Frost — gives presents to all the good kids.
After the October Revolution, public religious displays, including Christmas celebrations, were largely eliminated. The practice of discouraging, persecuting, and completely banning religious practice also spread to Soviet satellite states, like Albania, Romania, and East Germany.
But replacing the festivities was easier said than done. Foreign Policy reports Soviet efforts to introduce a brand new holiday failed.
Under Josef Stalin, in 1935, the tree and Ded Moroz became attached to the New Year.
"It became a civic, celebratory holiday, one that was ritually emphasized by the ticking of the clock, champagne, the hymn of the Soviet Union, the exchange of gifts, and big parties," writes Emily Tamkin in Foreign Policy.
