Definition
Organised crime refers to durable, structured groups that profit primarily from illegal markets — narcotics, trafficking, gambling, extortion, fraud — and that maintain internal hierarchies, division of labour, and methods of dispute resolution outside the law. Typical referents include Italian and Sicilian mafias, Latin American cartels, Russian-language criminal networks, Japanese yakuza, and the larger urban street-gang structures.
The category is contested. Legal definitions, beginning with the U.S. RICO statute (1970) and the UN Convention against Transnational Organized Crime (2000), set thresholds of group size, durability, and seriousness of conduct. Sociologists from Diego Gambetta to Federico Varese have argued that the most coherent mafias are best understood as private providers of protection in markets where the state cannot or will not enforce contracts.
Why it matters
How it works
Analytically, organised-crime scholarship asks how an illegal enterprise sustains itself. Markets in prohibited goods generate disputes that cannot be settled in court; the actors that earn most are those that can credibly enforce agreements, deter theft, and discipline competitors. Long-lived mafias accumulate this capacity through reputation, ritualised initiation, kinship ties, and selective violence; cartels add control of production and trafficking corridors.
The framework has policy and conceptual limits. Policy-wise, criminalising the structure rather than the markets it serves often fragments large groups into more dispersed and harder-to-trace networks without reducing supply. Conceptually, lumping street gangs, traffickers, white-collar conspiracies, and political-corruption networks under one label can obscure the very different incentive structures that produce each. The category remains useful when it stays specific about the organisational form under study.
