"The people who took part in the Poll Tax rebellion are Working Class heroes"
Andy Murphy - Class War

The UK Poll Tax Riots were a series of mass disturbances, or riots, in British cities during protests against the Community Charge (commonly known as the poll tax), introduced by the Conservative government led by Prime Minister Margaret Thatcher. By far the largest occurred in central London on Saturday March 31, 1990, shortly before the poll tax was due to come into force in England and Wales.

The disorder in London arose from a demonstration which began at 11am. The rioting and looting ended at 3am the next morning. This protest is called the Battle of Trafalgar because much of the rioting took place in Trafalgar Square.
