Alwhich of the following is believed to have played a role in the collapse of the soviet union

Joseph Stalin

Georgian-born revolutionary Joseph Stalin rose to power upon Lenin’s death in 1924. The dictator ruled by terror with a series of brutal policies, which left millions of his own citizens dead. During his reign—which lasted until his death in 1953—Stalin transformed the Soviet Union from an agrarian society to an industrial and military superpower.

Stalin implemented a series of Five-Year Plans to spur economic growth and transformation in the Soviet Union. The first Five-Year Plan focused on collectivizing agriculture and rapid industrialization. Subsequent Five-Year Plans focused on the production of armaments and military build-up.

Between 1928 and 1940, Stalin enforced the collectivization of the agricultural sector. Rural peasants were forced to join collective farms. Those that owned land or livestock were stripped of their holdings. Hundreds of thousands of higher-income farmers, called kulaks, were rounded up and executed, their property confiscated.

The Communists believed that consolidating individually owned farms into a series of large state-run collective farms would increase agricultural productivity. The opposite was true.
