Secular celebrations of the New Year in Russia, also known as Novy God, are derived from traditions associated with Christmas; New Year trees (yolka) are put up in homes and in public, and Ded Moroz (Grandfather Frost) delivers presents to children for New Year's Day in a similar manner to Santa Claus. The practices date back to the early 20th century: due to the Communist Party's stance of state atheism and a larger series of anti-religious policies, the celebration of Christmas and other religious holidays was widely discouraged. In particular, Christmas trees were singled out for originating from World War I enemy Germany, and being a symbol of the bourgeoisie. In 1935, Soviet politician Pavel Postyshev and other high-ranking officials began to promote the concept of New Year trees as a wide, secular tradition—representing happiness and prosperity among youth. Even with the reinstatement of religious holidays after the dissolution of the Soviet Union, Novy God has remained a popular celebration in modern Russia
