But they are not the first. Humans have lived, and thrived, through more than one great realignment. What makes an age a revolutionary one? And how do they end? In this major new work, Fareed Zakaria masterfully investigates eras that have shattered and shaped humanity. Four such periods hold profound lessons for today. The “Glorious Revolution” in Britain showed that major political change could happen peacefully. Next, the French Revolution, a dramatic decade and a half that devoured its ideological children and left a bloody legacy that haunts us to this day. Finally, the mother of all revolutions, the Industrial Revolution, which catapulted Britain and the US to global dominance and created the modern world. As few public intellectuals can, Zakaria combines intellectual range, deep historical insight, and uncanny prescience to reframe and illuminate a turbulent present.
