Reaction of the Peasants
The problem was that many peasants hated the idea. The way they saw it, the old regime had been destroyed to give them land, not make them share it with everyone else. Stalin had to make collectivisation obligatory in 1930 to get the programme off the ground. Even then, some peasants refused, and some even set fire to the food they produced rather than hand it over to the government. Stalin used his propaganda machine to identify these people as capitalist kulaks who were trying to destroy the Soviet Union. Individuals were sent to the gulag (prison camps in frozen Siberia), or, where whole villages resisted, all their food was taken and they were left to starve.
The End Result
By World War 2, pretty much all of the Soviet Union’s land had been collectivised. And the supply of food to the rapidly growing industrial cities increased significantly. The USSR even began to export food for the first time. The only black mark against the programme was the small matter of the 3 to 5 million people who were either executed or imprisoned as Stalin enforced the scheme. Oh, and the 5 million more who died of starvation between 1930 and 1933. But Stalin wasn’t so bothered about that. He’d increased food production and, maybe even more importantly for him, terrified the USSR’s peasants and broken their ability to oppose him.
Stalin Tightens his Grip on Power
Although Stalin had attained a pretty secure grip on power by the late 1920s, he wasn’t fully satisfied. In fact, he was downright paranoid that opposition forces were gathering to take him down. Importantly, he didn’t just believe that there were figures in the Party who were out to get him, but also that many ordinary Russians, connected in a worldwide capitalist conspiracy to destroy the Soviet Union, were looking to remove him. Well, that’s how he explained it to the world, anyway. Really no such conspiracy existed, and was merely an excuse to terrorize the population into obedience and remove the rivals who allegedly were behind this plot.
