i disagree, yakuza and triads were formed respectively at the ending of 1800 and beginning of 1800, i'm talking of facts, not legends according to legends italian mafias (cosa nostra/camorra/ndrangheta) were formed in 1300, but it's just a legend, if we look historical facts sicilian mafia and camorra beginning of 1800 and ndrangheta ending of 1800 i've never see any real proof yakuza and triads were active in 1700, and any of thieves in law active outside prisons
