Question

Quizplus · Accepted Answer

The Japanese occupation of China (1937-1945) weakened the authority of the Nanjing government and created a power vacuum in many parts of China. The Communists, who were already engaged in guerrilla warfare against the Nationalists, were able to capitalize on the chaos and gain support from peasants, workers, and intellectuals. The Communists also formed alliances with other anti-Japanese forces, such as the guerilla forces led by Zhu De and Peng Dehuai, which helped them to expand their influence and control over rural areas. By the end of World War II, the Communists were in a strong position to challenge the Nationalists for control of China.
