Being a football fan is both a privilege and a burden. When you're winning, it's the best thing on Earth, and when you're not, it's the end of the world. And the thing about being a football fan is, whichever way fortune swings, you're stuck with the game and your team for life. We've come to accept the great hold football has on us. But how did this happen? How did we become so entirely wrapped up in the game? How did we become football fans?

Savage Enthusiasm traces the evolution of the football fan from the sport's earliest origins right up to the present day, exploring how football became the world's most popular spectator sport, and why it became the undisputed game of the people.

The history of the football fan is also a social history, a political history, a history of the media, and a history of the game itself. Primarily, though, it's a history of people going out to watch their teams, win or lose, then going back again and again. It's a celebration of watching football, dedicated to anyone who has ever had their heart gladdened or saddened by the game.
