Jalisco New Generation Cartel
The Jalisco New Generation Cartel (Spanish: Cártel de Jalisco Nueva Generación, pronounced [ˈkaɾtel ðe xaˈlisko ˈnweβa xeneɾaˈsjon]), also known as CJNG, is a Mexican criminal syndicate based in Jalisco founded and headed by Nemesio Oseguera Cervantes, commonly known as El Mencho, until he was killed by the Mexican Army in 2026. The cartel has been characterized by extreme violence and public relations campaigns. Though the CJNG is known for diversifying into various criminal rackets, drug trafficking (primarily cocaine and methamphetamine) remains its most profitable activity. The cartel has been noted for cannibalizing some victims during the training of new sicarios or members, as well as using drones and rocket-propelled grenades to attack enemies.
CJNG started in 2009 as one of the splits of the Milenio Cartel, the other being La Resistencia. CJNG defeated La Resistencia and took control of Milenio's smuggling networks. CJNG expanded its operation network from coast to coast in six months, making it one of the criminal groups with the greatest operating capacity by 2012. Following the emergence of the cartel, homicides, kidnappings and discoveries of mass graves spiked in Jalisco. By 2018, the CJNG was believed to have over 100 methamphetamine labs throughout Mexico. Based on average street value, its trade could net upwards of $8 billion for cocaine and $4.6 billion for crystal meth each year. The CJNG are fighting the Nueva Plaza Cartel for control of Guadalajara; La Unión Tepito for Mexico City; Los Viagras and La Familia Michoacana for the states of Michoacán and Guerrero; Los Zetas in the states of Veracruz and Puebla; Cártel del Noreste in Zacatecas; the Sinaloa Cartel in Baja California, Sonora, Ciudad Juárez, Zacatecas and Chiapas; as well as the Santa Rosa de Lima Cartel in Guanajuato. They have an alliance with the Cártel del Golfo in Zacatecas and La Línea in Juárez.
CJNG is considered by the Mexican government to be one of the most dangerous criminal organizations in Mexico and the most powerful drug cartel in Mexico. It is also considered the cartel with the most paramilitary firepower. CJNG is heavily militarized and more violent than other criminal organizations. It has a special operations group for specific types of warfare. Its hitman training program is strict and professional. The cartel is best known for its fights against the Zetas and Templarios, it has fought La Resistencia for control of Aguililla, Michoacán, and its surrounding territories.
In later time, it would be revealed that a major part of El Mencho's influence in the CJNG actually came through his marriage to Rosalinda González Valencia, herself highly involved in drug trafficking.
From 2018 to 2020, the CJNG engaged in 298 reported acts of gang-related violence, more than any other cartel. By 2020, US officials considered CJNG its "biggest criminal drug threat" and Mexico's former security commissioner called it "the most urgent threat to Mexico's national security". The group was designated as a terrorist organization by the United States Department of State during Trump's second term in February 2025.
