This book is an accessibly academic exploration of the history of the Communist Party of China. Employing a wealth of reliable primary sources and a professional theoretical framework, the author conducts a thorough analysis of the pivotal period in the transformative era from the December Conference of 1937 to the Sixth Plenary Session of the Party's Sixth Central Committee in 1938, and thus, makes a detailed portrayal of how the first generation of central Party leadership, with Mao Zedong at its core, was established and consolidated.
