The PRC History Group is a network of scholars with interests in the history of the People’s Republic of China. We define history broadly, to encompass a wide variety of disciplinary approaches, and we understand the history of the PRC to include decades prior to the official change of state power in 1949.

Hoover’s many Chinese collections document political, economic, and social developments during the revolution of 1911, the warlord period, the civil war, and the post-1949 period. Holdings on pre-1949 Republican China, including Nationalist government documents and Chinese Communist Party materials, are particularly robust. Also available are accounts of non-Chinese public servants, military officers, engineers, journalists, and scholars who shaped or witnessed developments in China.
