The Chinese Communist Revolution of 1949 was one of the most massive revolutions in world history, let's understand why:
During the last decades of the Empire of China, it was discussed which political system would lead China to become a powerful, modern and economically strong nation, in other words, overcome the "backwardness" of China's culture. The answer came with the strength of the Communist troops after the end of the WWII. In a clever move in 1949, they proclaimed the People's Republic of China and took control of China over the Nationalists troops.
As mentioned before, the main goal of the government modernized the country, and the Communist party attempt to achieve this was the Great Leap Forward (1958-1962), a campaign to organize its vast population to meet China's industrial and agricultural dilemmas.
