1929

The ruling PRI party establishes an informal accommodation with drug traffickers, allowing cartel operations in exchange for political loyalty and controlled violence — a system that holds for seven decades.

2000

PRI loses the presidency for the first time, ending 71 years of single-party rule and collapsing the managed accommodation structure that had kept cartel violence in check.

2006

President Felipe Calderón deploys the military against cartels, launching the modern drug war; the offensive kills and arrests top leaders but fragments large cartels into dozens of smaller, more violent successor groups.

2008

Cartel violence surges as fragmented groups compete for territory; over 6,000 drug-war deaths are recorded this year alone, marking the conflict's first major escalation beyond manageable levels.

2010

CJNG is founded by Nemesio Oseguera Cervantes ("El Mencho") as a Sinaloa Cartel offshoot, rapidly expanding using military-style tactics including armored vehicles and explosive-laden drones.

2016

Sinaloa Cartel leader Joaquín "El Chapo" Guzmán is captured and extradited to the United States in 2017, triggering an internal power struggle between his sons (Chapitos) and co-founder Ismael "El Mayo" Zambada.

2019

The government's botched attempt to arrest a Chapo son in Culiacán triggers a cartel military assault on the city, forcing security forces to retreat and release him — exposing severe limits of state authority.

2024

El Mayo Zambada is arrested in the United States, deepening the Sinaloa Cartel's internal fracture between the Chapitos and Mayo factions, intensifying intra-cartel warfare alongside ongoing CJNG and Cartel del Noreste expansion.

US: Primary market for drugs ($50B+/yr). US fentanyl precursor demand drives supply chain. US Treasury/OFAC sanctions. Trump FTO designations Jan 2025. US conducts naval strikes on drug boats near Latin America (2025).

CHINA: Fentanyl precursor chemical suppliers (primarily Sichuan-based companies) supply cartels. No direct state sponsorship but Chinese chemical companies are structural enablers.

Cartels operate as de facto sovereigns in controlled territories (30-35% per NORTHCOM). Culiacan 2019: Sinaloa overrode Mexican state decision. Trump FTO designation creates legal framework for potential US unilateral operations. Sinaloa internal war (2024): Chapitos faction vs. 'Los Mayos' faction split after arrest of El Mayo Zambada — created unprecedented cartel-on-cartel violence. CJNG is most aggressive expansion force.

Analyzed in depth in prior session as sovereignty gap case study. ACLED ranks Mexico top-10 globally for conflict severity. Gang violence in Ecuador and Haiti connected to Mexican cartel supply chains and organizational models.
