The real Peaky Blinders were not middle-aged crime lords running an empire after the First World War. They were a street gang of teenagers and young men in the slums of late Victorian Birmingham, grown out of the loose slogging gangs that fought police crackdowns on gambling and street sports. Their public debut came in March of 1890, when a gang led by Thomas Mucklow fractured the skull of George Eastwood with belt buckles as he sat drinking a ginger beer in a Small Heath pub. Then they wrote to national newspapers to claim the attack under their new name.

This episode traces how that act of branding worked, how tailored jackets, bell-bottom trousers, silk scarves, and flat caps became an armor of status in a filthy slum, and how the gang moved into protection rackets, extortion, and illegal bookmaking. It also follows their collapse, squeezed between Billy Kimber’s Birmingham Boys at the racecourses, a disciplinarian police chief named Rafter who arrived in 1899, stricter sentencing, better schooling, and the First World War. By the 1920s the survivors had fled the city center, and by the 1930s the Sabini gang held the region’s rackets.

• The razor blade legend fails on dates alone. Gillette introduced its replaceable safety razor in 1903, and the first British factory making them opened in 1908, years after the gang took its name in 1890.
• Peaky was common slang for a peaked flat cap, and blinder was Birmingham slang for someone strikingly well dressed.
• Arrest records show how young they were: David Taylor carried a loaded firearm at 13, and Baby-Faced Harry was arrested at 19 in 1904 for stealing a bicycle.
• A tactic called constable baiting, championed by a member known as Kevin Mooney, left officers dead in 1897 and 1901, injured hundreds more, and drove many to quit the force.
• Henry Lightfoot, the first person named in print as a Peaky Blinder, went on to fight at the Battle of the Somme in 1916.
