How did planned economy start?

Planned economies emerged in the early 20th century, primarily in response to the perceived failures of capitalism, particularly during the Great Depression. The most notable example is the Soviet Union, which implemented a centrally planned economy following the Russian Revolution of 1917. Governments aimed to control production, distribution, and prices to achieve economic stability and equality. This model was later adopted by various countries, often with the goal of rapid industrialization and social welfare.
