Final answer:
The Chinese revolution was successful primarily due to popular support for the Communist leaders.
Step-by-step explanation:

Mao Zedong and other Communist leaders appealed to the landless and poor farmers by promising equal distribution of land and wealth. The message of Mao resonated with the majority of the Chinese population, especially in contrast to the corruption and inefficiency of the Nationalist regime under Chiang Kai-shek.
