The formative years of the Chinese Communist Party (CCP) have long remained one of the most obscure periods in the recent past of China. There remain many puzzles about why and how the alliances, between the CCP and the Kuomintang (KMT) on the one hand and Soviet Russia on the other, came about in the early 1920s.
For the last four years I have been studying the establishment and first years of the CCP, at the same time paying attention to the foundation and first years of the Indische Sociaal Democratische Vereniging (ISDV), which was later to become the Partai Kommunis Indonesia (PKI). In this connexion I have been specially interested in outlining the origins of that strategy whereby Communist Party members entered a nationalist mass movement and tried to capture it from within.
