It began as a demonstration of scale. Two hundred thousand people converged on Trafalgar Square. The mood was festive, indignant, but orderly. The Community Charge, dubbed the Poll Tax, was seen as fundamentally unfair, taxing the duke and the cleaner the same flat rate. By late afternoon, the scale tipped.
The violence was not a single event but a series of fractures. A cordon of police near the Square was breached. A few individuals began throwing placard sticks, then bottles. The response was containment, then dispersal. The crowd, too dense to move, compressed. People were trapped. The sound changed from chants to the smash of glass and the thud of projectiles on riot shields. Fires were lit in the street. The battle lasted for hours, spilling into the West End.
Over 400 people were injured, and 340 arrested. The damage was estimated at £400,000. The government called it the work of a militant minority. The protesters saw it as the inevitable result of a government that would not listen.
The riot was a hinge. It demonstrated that the British tradition of peaceful protest had its limits under perceived injustice. It wounded the Thatcher government irreparably. Within a year, she was gone, and the Poll Tax with her. The event asked a blunt question about governance: how much can you ask of people before they refuse, not with a vote, but with a brick?
