The Underworld, in a criminal context, refers to the network of organized crime and illegal activities that operate outside the law. This includes various groups and individuals involved in activities such as drug trafficking, human trafficking, and extortion. The Underworld often has a hierarchical structure, with leaders who control operations and lower-level members who carry out tasks. Criminal organizations within the Underworld, such as the Mafia or cartels, often engage in violence and corruption to maintain power and influence. Law enforcement agencies work to combat these activities, but the Underworld remains a persistent challenge due to its secretive nature and the vast sums of money involved.
