Banditry is the life and practise of bandits. The New English Dictionary on Historical Principles (NED) defined "bandit" in 1885 as "one who's proscribed or outlawed; hence, a lawless desperate marauder, a brigand: usually applied to members of the organised gangs which infest the mountainous districts of Italy, Sicily, Spain, Greece, Iran, and Turkey". In modern usage the word might become a synonym for "thief", hence the term "one-armed bandit" for gambling machines that can leave the gambler with no money.
Origin of the word
The term bandit (introduced to English via Italian around 1590) originates with the early Germanic legal practise of outlawing criminals, termed *bannan (English ban). The legal term in the Holy Roman Empire was Acht or Reichsacht, translated as "Imperial ban". In modern Italian the equivalent word "bandito" letterally means banned or a banned person.
Marauding was one of the most common peasant reactions to oppression and hardship. The growth of warlord armies in China was additionally accompanied by a dramatic increase in bandit activity in the republican period; by 1930 the total bandit population was estimated to be 20 million.
"Social banditry" is a term invented by the historian Eric Hobsbawm in his 1959 book Primitive Rebels, a study of popular forms of resistance that additionally incorporate behaviour characterised by law as illegal. He further expanded the field in the 1969 study Bandits. Social banditry is a widespread phenomenon that has occurred in a large number of societies throughout recorded history, and forms of social banditry still exist, as evidenced by piracy and organized crime syndicates. Later social scientists have additionally discussed the term's applicability to more modern forms of crime, like street gangs and the economy associated with the trade in illegal drugs.
