1. Under Stalin's leadership, the Soviet Union implemented rapid industrialization and collectivization programs through Five-Year Plans. Collectivization aimed to merge small farms into larger collective farms to more efficiently supply food and labor for industrialization, though it faced resistance and led to famine. Rapid industrialization established a planned economy with strict production targets and worker incentives to transform the Soviet Union into a self-sufficient, militarily strong state. While coordination issues caused over and underproduction, the programs ultimately gave the Soviet Union a strong industrial base and modernized the economy.
