Mao Zedong and the twelve other young men who founded the Chinese Communist Party in 1921 could hardly have imagined that less than thirty years later they would be rulers. On its hundredth anniversary, the party remains in command, leading a nation primed for global dominance. Tony Saich tells the authoritative, comprehensive story of the Chinese Communist Party-its rise to power against incredible odds, its struggle to consolidate rule and overcome self-inflicted disasters, and its thriving amid other Communist parties' collapse. Saich argues that the brutal Japanese invasion in the 1930s actually helped the party. Once in power, however, the Communists faced the difficult task of learning how to rule. Leninist systems are thought to be rigid, yet the Chinese Communist Party has proved adaptable. From Rebel to Ruler shows that the party owes its endurance to its flexibility. But is it nimble enough to realize Xi Jinping's "China Dream?" Challenges are multiplying, as the growing middle class makes new demands on the state and the ideological retreat from communism draws the party further from its revolutionary roots. The legacy of the party may be secure, but its future is anything but guaranteed.
