Since gambling pre-dates recorded history it comes as little surprise that evidence of match fixing is found throughout recorded history. The ancient Olympic Games were almost constantly dealing with allegations of athletes accepting bribes to lose a competition and city-states which often tried to manipulate the outcome with large amounts of money. These activities went on despite the oath each athlete took to protect the integrity of the events and the severe punishment sometimes inflicted on those who were caught. Chariot racing was also dogged by race fixing throughout its history.
