The first woman to win an Olympic boxing gold medal became the first to repeat the feat on Saturday when Britain's Nicola Adams retained her flyweight title by beating France's Sarah Ourahmoune.
Adams, 33, became the first British boxer to win two successive golds since London policeman Harry Mallin won the middleweight division at the 1920 Antwerp and 1924 Paris Games.
Ourahmoune's silver was France's fifth medal of the tournament.
Ren Cancan of China, the 2012 silver medallist, and Colombia's Ingrit Valencia Victoria took bronze as losing semi-finalists.
Women's boxing was introduced to the Olympics at the 2012 London Games, with Adams the first of three champions.
"The gold rush continues," she told the BBC. "I'm now officially the most accomplished amateur boxer Great Britain has ever had. I can't believe it."

Adams, from Leeds, has won Olympic, European and Commonwealth golds.
She started strongly against the 15th-ranked Ourahmoune, winning the first of four two-minute rounds on all three judges' scorecard.
She improved further in the second, again winning across the board after pinning back her opponent with speed and accuracy.
Ourahmoune, who won bronze at this year's World Championships, battled back to take the third and also produced a spirited performance in the final round.
Both boxers celebrated at the final bell, but it was Adams whose arm was raised in victory after again impressing all three judges.
