This book examines and theorizes the dynamics and complexities of leadership in citizenship education in junior secondary schools in Shanghai, China. Specifically, it examines from a macro- and micro-political theoretical perspective the interactions between principals and school party secretaries (SPSs), and how they respond to the demands of macro- and micro-political actors. This qualitative empirical research found four major school leadership/citizenship education scenarios in which principals and SPSs addressed the interests of different macro- and micro-political actors. Moreover, principals and SPSs enjoyed a complicated working relationship at the micro-political (school) level in which they collaborated to fulfill their responsibilities and respond to school macro- and micro-political actors, while competing for power over leadership in citizenship education. Principals’ and SPSs’ leadership in citizenship education was shaped by inter-related factors, including diverse influences in a multi-leveled world, the integration of politics and education, the demands of macro- and micro-political actors, and personal factors. To interpret these findings, this study proposes a theoretical framework for understanding leadership in citizenship education in China as a political exercise. This theoretical framework is useful for understanding the complexity of school and citizenship education leadership, the micro-political relationship between Chinese principals and SPSs, and their dynamic and complex interactions with macro- and micro-political actors.
