From El Mencho to El Chapo to Pablo Escobar: How the world’s most notorious drug lords built global empires

Nemesio Oseguera Cervantes, known as El Mencho, died after a security operation aimed at arresting him in Jalisco state. The defence ministry said he was seriously injured during clashes between the army and members of the Jalisco New Generation cartel, or CJNG, and later died while being transferred to Mexico City. Four cartel members were killed in Tapalpa, and three soldiers were injured. Vehicles and heavy weapons were seized. The United States had offered a 15 million dollar reward for information leading to his capture and said it provided intelligence support. His death removes one of the most wanted drug traffickers in the world and closes a chapter in Mexico’s long conflict with organised crime.

El Mencho built a major drug empire comparable to El Chapo and Pablo Escobar

Nemesio Oseguera Cervantes rose from a former police officer to the head of the Jalisco New Generation Cartel, widely known as CJNG. Over the past decade the group expanded rapidly across Mexico and into international drug markets. Authorities in Mexico and the United States accused it of trafficking large amounts of cocaine, methamphetamine and fentanyl.




CJNG became known for open confrontations with security forces. Roadblocks, burned vehicles and coordinated attacks were part of its method. In response to the operation that led to Oseguera’s death, violence was reported in several states. That pattern had been seen before during attempts to capture senior figures.

The US government listed him among its most wanted fugitives. A reward was offered and sanctions were imposed on businesses linked to the cartel. Despite this pressure, he managed to avoid arrest for years.

Joaquín Guzmán ‘El Chapo’ built the Sinaloa cartel into a global network

Before El Mencho, the name most associated with Mexican drug trafficking was Joaquín Guzmán, widely known as El Chapo. He led the Sinaloa Cartel, which became one of the most powerful trafficking groups from the late twentieth century onwards.

Guzmán began in the 1980s within the Guadalajara cartel and later helped shape the Sinaloa organisation after that group split. Under his leadership, the cartel refined smuggling routes into the United States. Tunnels under the border, concealed shipments and maritime routes were used to move marijuana, cocaine, heroin and methamphetamine.

He was first arrested in 1993 and later escaped from prison in 2001. A second dramatic escape followed in 2015 through a tunnel built beneath his cell. Each escape damaged public confidence in Mexico’s prison system. He was finally captured in 2016 and extradited to the United States. In 2019 he was sentenced to life imprisonment in a US federal court.

In parts of Mexico, his image took on a strange cultural weight. Songs were written about him. Some communities viewed him as a benefactor. At the same time, the violence linked to cartel rivalries led to thousands of deaths.

Pablo Escobar turned cocaine trafficking into a global business

Years earlier in Colombia, Pablo Escobar had already shaped the model of the modern drug empire. As leader of the Medellín Cartel, he dominated the cocaine trade during the 1980s and early 1990s.

Escobar controlled supply chains that moved cocaine from South America into North America and Europe. At the height of his power he was believed to be among the richest criminals in the world. His wealth funded private estates, aircraft and even a zoo on his property in Colombia.

Violence defined his campaign against the state. Bombings, assassinations and intimidation were used to resist extradition to the United States. More than one hundred people were killed in the bombing of a commercial flight in 1989, an attack widely attributed to his network.

He was shot dead by Colombian security forces in 1993 after months in hiding. Soon after, the Medellín cartel fragmented.

Drug cartels continue to reshape organised crime in Latin America

The deaths or imprisonment of high-profile figures have not ended the trade. Instead, organisations have splintered, reformed and shifted routes. Synthetic drugs such as fentanyl have altered the economics of trafficking, reducing reliance on traditional coca cultivation.

Mexico remains a central corridor for drugs entering the United States. Colombia continues to face challenges linked to coca production. Enforcement efforts have intensified, yet demand abroad persists.

From El Mencho to El Chapo and Pablo Escobar, each figure marked a different stage in the evolution of organised crime. Their names became shorthand for wider systems built on smuggling, corruption and violence. Removing one leader rarely dismantles the structure beneath. Quietly, others tend to step forward.
