Team GB's Nicola Adams fought a strong bout to be crowned the first female boxer to win an Olympic gold.
The 29-year-old from Leeds outclassed her opponent Ren Cancan from China at the start of the first round and went on to win 16-7 in a historic fight.
"It's a dream come true," Adams told BBC Sport after the bout.
"I am so happy and overwhelmed with joy right now. I have wanted this all my life and I have done it. To be taking the gold medal back to Leeds will be special."
Women's boxing pioneer and former world champion Barbara Buttrick was in the crowd watching the first female Olympic final and praised her fellow countrywoman.
There had been doubts that Adams would ever reach the Olympic Games after she suffered a major back injury that left her unable to get out of bed for three months. However, following funding from the National Lottery, Adams and her fellow female boxers were given the chance to train with the male boxers at top-class facilities.
"When I was around, I would never have dreamed women boxers would ever get into the Olympics," said Buttrick.
"But now they've got that credibility and that will bring a lot more girls into it because they'll feel more comfortable going into a gym."
London 2012 has been a major success for British boxers, with four male fighters guaranteed at least a bronze medal – making it the most successful Olympics for the nation since the Melbourne 1956 Games.
There has also been strong support at the ExCel centre, where the crowds, including many staying in central London hotels, have been treated to some thrilling action.
