The Civfil War that erupted between nationalists and communists after the Bolshevik revolution ended in 1921, with the communist Red Army winning.
In 1946, tensions escalated between the Nationalist government, led by Chiang Kai-shek, and the Communist Party of China, led by Mao Zedong, following the end of World War II. After a brief period of cooperation during the war, civil war erupted again as both sides sought control over China. The Nationalists aimed to consolidate power, while the Communists gained popular support, particularly in rural areas. This conflict ultimately led to a full-scale civil war that would last until 1949, ending with the establishment of the People's Republic of China under Communist rule.
In the Chinese civil war, the communists had a superior strategy of guerrilla warfare, ability to win the hearts of and extract resources (as well as intelligence) from the people in the countryside and better discipline in the party. The nationalists over-spread their forces, concentrated on holding important cities (to which they were later surrounded, their weapons being taken by the communists and troops being assimilated to the Red Army). The nationalists had weapons and equipment from the US, but they failed to use them effectively; the communists had equipment taken from the defeated Japanese in the north (as well as the nationalists). The nationalists mis-administered areas under their control, alienating most of the population, resulting in corruption and having huge inflation.
Mao Zedong preached a philosophy that appealed to China's poor. (He promised to end oppression from landlords and government officials, etc.)
In 1908 the last emperor of China, Xuangtong Emperor of the Great Qing, Kangde Emperor of Manchukuo was born. In 1918, the USS Monocacy incident happened after the Chinese fired on an American ship.
Hebrew Communists ended in 1948.
Chinese peasants supported the communists and Mao Zedong primarily because the communists promised land reforms and an end to the feudal system, which directly addressed their economic hardships. In contrast, the Nationalists under Chiang Kai-shek were seen as corrupt and largely focused on urban elites, often neglecting the needs of rural populations. Additionally, the communists effectively mobilized peasant support through grassroots organizing and by promoting social equality, which resonated deeply with the agrarian majority. This combination of land promises and grassroots appeal ultimately swayed peasant loyalty towards the communists.
