Boxing Day 1920, and 53,000 men, women and children pack inside Goodison Park. The extraordinary crowds have come to watch two local rivals play a match for charity. But this is no ordinary charity fixture. Eleven of the players are international celebrities and their team is the biggest draw in British - and world - football. Yet they are all full - time factory workers - and they are women. They are the ladies of Dick Kerr electrical works. And the male football establishment is terrified by them. With the men away fighting from 1914 - 1918, most of the workers in the factories of northern England were women. And many factories had a ladies' football team. In December 1917, the team from the Dick Kerr factory challenged the ladies of the nearby Arundel Coulthard Foundry to a charity match. It was the first of 828 games for Dick Kerr Ladies as over the decades they scored more than 3,500 goals and raised the equivalent of GBP1 million for an array of charities. By 1920, ladies football was a major spectator sport. But away from the cheering terraces are bastions of professional men's football viewed the mass popularity of women's soccer with increasing alarm.On 5 December 1921 the Football Association met in London. After a brief debate behind closed doors it unanimously passed an urgent resolution: women's football was banned from all professional football grounds. Dick Kerr Ladies did not give in, playing their matches on parkland with thousands of spectators turning up to watch. But constant pressure from the FA meant that one by one, teams began to fold,. It would take until 1971 for the FA to life its ban. Today, women's football has once again claimed a place in the global games. But it came too late for the pioneers of the sport: Preston Ladies - nee Dick Kerr Ladies - played their last match in 1969.
