This chapter explores the ideas and political movements of the CYP in warlord China through three sections. The first section characterizes the CYP’s ideology by its cultural conservatism, political intellectualism, and integral nationalism based on a combination of transformed federalism and corporatism specific to the Chinese sociopolitical context, particularly through the ideological debates of the CYP founders with Communists between 1924 and 1927. The second section delves into the CYP’s mass political movements of different types. Finally, as a precondition for the CYP’s rapid development in north China and Manchuria, the third section explores how the CYP created friendly political environments by collaborating with leading regional warlords in different periods.
