The Medellín Cartel is the Columbian drug cartel formed in the 1970s and is the primary criminal organization featured in Narcos. Originating in the city of Medellín, the cartel operated across Bolivia, Colombia, Honduras, Peru, and the United States, and later expanded into Canada and Europe.
It was founded and run by Ochoa Vázquez brothers Jorge Luis, Juan David, and Fabio, together with Pablo Escobar and José Gonzalo Rodríguez Gacha.
At the height of its operations, the Medellín Cartel smuggled tons of cocaine each week into countries all over the world and profited over $420,000,000 per week. For a short span of time, the Medellín Cartel supplied 84% to 90% of the United States market and 80% of the global cocaine market.
