How does a figure like Richard III or Macbeth ascend to the throne? Such a disaster, Shakespeare suggested, could not happen without widespread complicity. His plays probe the psychological mechanisms that lead a nation to abandon its ideals and even its self-interest. Why would anyone, he asked himself, be drawn to a leader manifestly unsuited to govern, someone dangerously impulsive or viciously conniving or indifferent to the truth? Why, in some circumstances, does evidence of mendacity, crudeness, or cruelty serve not as a fatal disadvantage but as an allure, attracting ardent followers?
