The emergence of modern Brazilian criminal organisations can be traced back to the boom in incarceration and prison overcrowding in the 1990s. During this period, important changes were forged within prison spaces including the emergence of prison groups that, years later, would become criminal organisations. This development reconfigured local criminal dynamics by connecting organised criminality to incarceration. Among the groups that emerged within local prisons, the Primeiro Comando da Capital – PCC [The First Capital Command] – is undoubtedly the most relevant in terms of its scope, size, economic resources, and stability.
