This document summarizes different theories and typologies of followership. It discusses the work of Abraham Zaleznik, Robert Kelley, Ira Chaleff, and Barbara Kellerman in categorizing different types of followers based on factors like motivation, behavior, level of engagement, and degree of support/challenge towards leaders. Kellerman's typology identifies five types of followers: isolates, bystanders, participants, activists, and diehards. The document concludes that good followers actively support effective leaders and oppose ineffective ones, while bad followers do nothing or take opposing stances regardless of the leader's effectiveness. Good leadership requires understanding different followers and creating more leaders.
