This chapter lays the groundwork by examining the fundamental relationship between leadership, power, and influence. It traces the concept of power from classical philosophy to Max Weber’s foundational sociological definition. The analysis then shifts from a leader-centric view to explore power as a complex social process, examining its sources, psychological impacts, and the dynamics of micro-politics. The chapter culminates in a case study of Taylorism and Henry Ford to illustrate how abuses of power become normalized.
