Sinaloa Cartel

The Sinaloa Cartel — also known as the Pacific Cartel or the Federation — emerged from the Guadalajara Cartel’s 1989 fragmentation and became the most powerful drug trafficking organization in the world. Led by Joaquín “El Chapo” Guzmán Loera and Ismael “El Mayo” Zambada García from Culiacán, it dominated production and distribution of heroin, methamphetamine, cocaine, and fentanyl to the United States.

The cartel historically preferred corruption over confrontation, pioneered sophisticated cross-border tunnels, and built global operations spanning over 50 countries. El Chapo’s two dramatic prison escapes (2001, 2015), recaptures, and 2019 life sentence at ADX Florence made him the world’s most notorious drug lord. Mayo Zambada’s July 2024 capture — reportedly lured onto a plane to the US by Chapo’s son — fractured the organization into warring factions, triggering severe violence in Sinaloa.
