While in most prisons in the world, one of the guards’ main duties is to prevent clashes between prisoners, in Thai penal institutions boxing matches between inmates are allowed and encouraged by authorities. Inmates fight to earn cash and fame or to reduce their sentence. Some of them even have a chance to win a place in the country’s boxing team. There are no restrictions on who can enter a ring – among fighters there are people who are serving a life sentence for most serious crimes. Prison fights in Thailand have a long history that dates back to 18th century when one Thai fighter was pardoned by the king who was impressed by his victories in prison fights.
