The Medellín Cartel was a large network of drug smugglers and suppliers founded by Pablo Escobar. At its peak, the cartel spanned over ten countries and was the largest, most successful, and most dangerous cartel in the world. Escobar, during his most successful time, was the richest drug lord in the world, and 7th richest man overall. After escaping from a prison which he had designed, Escobar spent years fleeing from law enforcement, unable to run his cartel to the fullest extent. Eventually, Escobar was killed by Colombian National Police in 1992, ending the cartel's reign once and for all.
