Across continents and cultures, football derbies ignite passions like nothing else in sport. But when fierce loyalty curdles into violence, the results can be catastrophic. Derby Day Disasters is a harrowing exploration of the dark underbelly of world football's greatest rivalries-from the blood-soaked terraces of Glasgow and Belgrade to the riotous streets of Buenos Aires and Cairo.

With minute-by-minute breakdowns of deadly matches, forensic examinations of fan cultures like firms, ultras, and torcidas, and detailed analyses of political, social, and institutional failures, this book lays bare the fragile line between devotion and destruction.

Drawing on over a century of chaos-from the earliest pitch invasions to the tragedies of modern mega-stadiums-Derby Day Disasters is a global journey through the stadiums, streets, and scars left behind when football's tribalism turns fatal. This is not just a book about hooliganism-it's a chronicle of history, humanity, and how football mirrors society's deepest divides.
