The hot killing of Nemesio Oseguera Cervantes, the chief of the Cártel de Jalisco Nueva Generación (CJNG) who was once regularly referred to by means of his alias “El Mencho”, has as soon as once more introduced international consideration to drug-related violence in Mexico. His demise by the hands of the Mexican safety forces induced a wave of retaliatory violence that affected a number of states.
This case will certainly happen once more. Below Donald Trump, america executive has been ramping up power at the Mexican government to take more potent motion towards the cartels that visitors medicine around the border. So now is a superb second to mirror at the primary cartels running in Mexico and the underlying elements that maintain their operations.
For many years, Mexico had 3 primary drug trafficking teams: the Milenio cartel, the Sinaloa cartel and the Golfo cartel. Those organisations ruled drug trafficking till the Nineteen Eighties when the Mexican executive, below power from america, intensified its operations towards them. This power adopted the 1985 killing of American Drug Enforcement Management agent Enrique Camarena by means of organised crime figures.
However it wasn’t till 2006 that Mexico’s cartel panorama actually started to switch. That yr noticed the then-Mexican president, Felipe Calderón, deploy the Mexican military towards the cartels in a militarised “war on drugs”. The federal government’s process of concentrated on senior cartel figures led to those organisations to fragment into smaller teams.
For instance, a bunch of former Mexican particular forces commandos who had in the past acted because the enforcement arm for the Golfo cartel broke away to shape Los Zetas in 2010. More than a few different factions in different places in Mexico additionally arrange their very own organisations. Those integrated Beltrán Leyva, L. a. Familia Michoacana, Knights Templar (Caballeros Templarios), CJNG and Guerreros Unidos.
In 2014, following the kidnapping of 43 pupil academics within the Pacific state of Guerrero by means of Guerreros Unidos, President Enrique Peña Nieto escalated the offensive towards Mexico’s cartels. This resulted in additional fragmentation, with some more recent organisations akin to Santa Rosa de Lima specializing in oil robbery. Andrés Manuel López Obrador got here to energy in 2018 and pressed exhausting towards the Sinaloa cartel.
The detention of senior figures akin to Joaquín “El Chapo” Guzmán and Ismael “El Mayo” Zambada led to the Sinaloa cartel to damage into two factions: Los Chapitos which is led by means of El Chapo’s sons and Los Mayos which is headed by means of El Mayo’s lieutenants. CJNG took benefit of this second to amplify, positioning itself on the centre of Mexican drug trafficking.
The militarised warfare on medicine has no longer simply led to the collection of Mexican drug trafficking organisations to amplify, it has additionally resulted in a surge in violence. All through the Nineteen Nineties and early 2000s, violence in Mexico was once in truth declining. However since 2006, when Calderón first deployed the Mexican military towards the cartels, homicides have higher from round 10,000 in line with yr to over 30,000.

The upward push in violence may be in large part a result of the planned concentrated on of cartel leaders. Casting off management produces a surprising succession fight in an affected organisation, with violence ceaselessly therefore hired to forestall or reply to competitors trying out the brand new management.
Mexico’s cartel violence is most often extremely concentrated, with northern Mexico and the Pacific states experiencing the easiest murder ranges. This development displays trafficking routes. Mexico’s northern states are a key hall for smuggling medicine into america, whilst the Pacific coast serves as a significant access level from Asia for the chemical compounds used to provide fentanyl.
Maintaining cartel operations
The violence perpetrated by means of the cartels is enabled in large part by means of guns which can be smuggled into Mexico. Consistent with figures printed by means of america Bureau of Alcohol, Tobacco, Firearms and Explosives, greater than part of the guns seized from legal teams in Mexico come from america.
Analysis displays how shut the connection between US firearms and Mexican cartel violence is. One learn about from 2019 discovered that any building up in firearm manufacturing in america will increase violence in Mexico. And any other, printed a number of years previous, found out there was once a spike in homicides in Mexico’s northern states when america executive lifted restrictions at the sale of positive attack guns in 2004.

The Mexican executive filed a lawsuit in 2021 that sought to carry American gun makers in command of their contribution to the emerging violence in Mexico. Whilst the lawsuit was once rejected unanimously by means of america ultimate court docket in 2025, the Mexican government have persisted to press their US opposite numbers to take more impregnable motion towards fingers smuggling from north of the border.
Mexico’s president, Claudia Sheinbaum, made a speech days after El Mencho’s killing by which she asserted that if america executive needs Mexico to forestall drug trafficking, they “have to do their part” and get rid of the go with the flow of guns.
And, in spite of everything, it’s vital to recognise that the operations of the Mexican cartels are sustained largely by means of drug intake in america. Knowledge printed by means of the UN Place of job on Medicine and Crime means that drug seizures, in particular of fentanyl, have higher considerably since 2019.
Till america takes steps to extra successfully scale back call for for medicine amongst its personal electorate, Mexico’s fight towards cartel violence will proceed.
