Communist Academy, there were no specific instructions on how exactly it had to be implemented, except for liquidation of kulaks as a class. Stalin's revolution is often regarded as one of the factors which led to the severe Soviet famine of 1932–33, better known in Ukraine as the Holodomor. Official Soviet sources blamed the famine on counterrevolutionary efforts by the Kulaks, though there is little evidence for this claim. A plausible alternative explanation, supported by some historians, is that the famine occurred at least in part due to poor weather conditions and low harvests. The famine started in Ukraine in the winter of 1931 and despite the lack of any official reports the news spread by word of mouth rapidly. During that time restrictions on rail travel were set by authorities. Only next year in 1932-33 the famine spread outside of Ukraine to agricultural regions of Russia and Kazakhstan, while the "news blackout continued". The famine led to the introduction of the internal passport system, due to the unmanageable flow of migrants to the cities. The famine finally ended in 1933, after a successful harvest. Collectivization continued. During the second five-year plan Stalin came up with another famous slogan in 1935: "Life has become better, life has become more cheerful." Rationing was lifted. In 1936, due to a poor harvest, fears of another famine led to famously long breadlines. However, no such famine occurred, and these fears proved largely unfounded. During the second five-year plan, under the policy of "cultural revolution" , the Soviet authorities established fines that were collected from farmers. Citing Siegelbaum's Stakhanovism in her book Everyday Stalinism, Fitzpatrick wrote: "...in a district in the Voronezh Region, one rural soviet chairman imposed fines on kolkhoz members totaling 60,000 rubles in 1935 and 1936: "He imposed the fines on any pretext and at his own discretion - for not showing up for work, for not attending literacy classes, for 'impolite language', for not having dogs tied up... Kolkhoznik M. A. Gorshkov was fined 25 rubles for the fact that 'in his hut the floors were not washed'". Khrushchev Era 1955-1963 Nikita Khrushchev was a top expert on agricultural policies and looked especially at collectivism, state farms, liquidation of machine-tractor stations, planning decentralization, economic incentives, increased labor and capital investment, new crops, and new production programs.
