Medal summary

The distinction of Taekwondo at these Olympic Games was that this was the first time in the sport that eight gold medals were awarded to eight different NOCs. Europe took the lead and South Korea lost its dominance. The 2008 Olympics was the second time that South Korea, failed to medal in Taekwondo.
