For more than forty years, the Sinaloa cartel functioned less like a criminal gang and more like a parallel state inside Mexico, an organization so deeply embedded in the country’s economic, political, and social life that entire regions operated under its authority rather than the government’s. The wealth it generated was measured in the billions of dollars annually, moving through real estate, agriculture, construction, transportation, and finance, funding campaigns, buying silence, and at times proving more reliable as a source of order than the state itself. To understand how this happened, one has to go back to the geography and history of northwestern Mexico. The state of Sinaloa sits on Mexico’s Pacific coast, with the Sierra Madre mountains to the east and the Gulf of California to the west.

For most of the twentieth century, it was an agricultural region, but deep in the mountains, isolated communities had been growing opium poppies since the early 1900s. By mid-century, poppy cultivation was embedded in the rural culture of the Golden Triangle, the mountainous region where Sinaloa, Durango, and Chihuahua meet. Poverty was severe, government presence was minimal, and the crops that grew best in those highlands were the ones the outside world paid the most for. Marijuana and heroin had flowed out of those mountains for decades through networks of families and communities who had built their economic lives around the trade.

Through the 1950s and 1960s, Mexican traffickers began acting as middlemen between South American cocaine producers and the American market to the north. In the 1970s, a new generation of operators emerged from Sinaloa. The key figure was Miguel Ángel Félix Gallardo, known as El Padrino, who built a vast network called the Guadalajara Cartel. At its peak, it functioned as the central coordinating body for almost all major drug trafficking in Mexico, and it operated with a kind of license from the Mexican state.

The federal security directorate acted as a protector for major trafficking operations in exchange for cash and information on political dissidents. The traffickers and the state were not enemies; at various points, they were partners. That arrangement fractured catastrophically in 1985, when agents working for Félix Gallardo tortured and murdered DEA agent Enrique Camarena Salazar. The killing brought enormous American pressure on Mexico, and Félix Gallardo was arrested in 1989.

Before going to prison, from his prison cell and through intermediaries, he divided his empire among his associates. The Pacific corridor through Sinaloa went to a group of traffickers who would form the foundation of what became the Sinaloa cartel. Among them were Héctor Luis Palma Salazar and a man from the mountain village of La Tuna named Joaquín Archivaldo Guzmán Loera, known to the world as El Chapo. Guzmán was born in 1957 into a poor farming family in the Sierra Madre.

He entered the drug trade as a young man working logistics and transportation for Félix Gallardo’s network, and he moved up quickly because he was reportedly precise, reliable, and completely ruthless when he needed to be. When the empire was divided in 1989, he had positioned himself as a key figure inheriting the Sinaloa corridor. But the division did not bring peace; it brought war. A feud developed between the Sinaloa faction and the Tijuana-based Arellano Félix organization.

On May 24, 1993, at the Guadalajara International Airport, gunmen linked to the Arellano Félix organization attempted to assassinate Guzmán. They missed him but killed Cardinal Juan Jesús Posadas Ocampo in the crossfire. The event stunned the nation, and Guzmán was arrested in Guatemala shortly afterward, extradited to Mexico, and sentenced to more than twenty years in federal prison. Prison was barely an interruption.

From inside the Puente Grande maximum security facility, Guzmán allegedly continued managing his operation, cultivating relationships with prison staff and living in conditions that bore no resemblance to what the public imagined. On January 19, 2001, one day before he was scheduled to be transferred to a prison closer to the American border, Guzmán walked out of Puente Grande. The version most commonly told is that he left in a laundry cart. What is certain is that prison staff facilitated his escape, and that he returned to the mountains of Sinaloa, where he spent the next thirteen years rebuilding his organization into something that dwarfed anything that had existed before.

The decade that followed transformed the Sinaloa cartel into a global criminal enterprise. The first track of this expansion was infrastructure. The cartel became famous for sophisticated smuggling methods. American and Mexican authorities documented hundreds of cross-border tunnels attributed to Sinaloa, many with rail systems, ventilation, electricity, and hydraulic doors.

The tunnel discovered beneath the Otay Mesa border crossing in 2011 was described by federal agents as the most sophisticated ever found at that point, nearly a third of a mile long with reinforced walls and a rail cart. The organization also used semi-submersible vessels built in jungle workshops in Colombia and Ecuador, ultralight aircraft flying below radar coverage, commercial shipping containers with false compartments, catapults mounted on border fences, and human couriers. A 2011 United States Senate subcommittee report described Sinaloa as operating with the logistical complexity of a multinational corporation. The second track was financial.

The money was so enormous that laundering it became one of the organization’s most significant challenges. Investigators documented bulk cash smuggling, trade-based money laundering, real estate purchases, agricultural investment, and money service businesses. A 2010 RAND Corporation report estimated that Mexican trafficking organizations collectively generated between nineteen and twenty-nine billion dollars annually from American drug sales alone, and the Sinaloa cartel was widely described as the largest single entity in that ecosystem. The third track was political.

Researchers and journalists documented what they described as a systemic penetration of Mexican institutions at the federal, state, and municipal level. In municipalities across Sinaloa and Chihuahua, police chiefs, public officials, and local judiciaries operated under the same roof as the cartel, providing protection and ensuring business continued without interference. The phrase researchers use is capture, the capture of state institutions by criminal organizations. A joint report published by Mexican academic institutions in 2012 described entire regions where the cartel had effectively replaced the state as the primary provider of order, dispute resolution, employment, and social services, a system researchers called narco governance.

The Sinaloa cartel also operated in the context of a brutal multi-sided war between Mexican trafficking organizations. Through the 1990s and 2000s, the Gulf Cartel, the Juárez Cartel, the Tijuana Cartel, and the Zetas all fought for control of trafficking corridors and border crossings. According to DEA reporting and Mexican government analyses, the Sinaloa cartel was frequently the most capable combatant and more willing to use strategic alliances to gain advantages over its enemies. At the height of his power, Guzmán operated out of a series of compounds spread across remote areas of the Golden Triangle.

Accounts from people who visited described properties with satellite dishes, stables of thoroughbred horses, security perimeters staffed by armed men, kitchens with cooks who prepared food to order, and communication and intelligence infrastructure that would have been impressive for a small government agency. Court documents from his eventual trial described houses with hidden rooms and escape tunnels, some with hydraulic doors in the floor of bathroom showers that opened into underground corridors. Around this world grew what became known as narco cultura, which fused traditional norteño identity with conspicuous consumption. Expensive boots, custom belt buckles with gemstones, gold watches and chains worn as declarations, and the narcocorrido ballad form that celebrated specific cartel figures by name.

Private aircraft became potent symbols of cartel wealth, and the rancho carried a specific cultural meaning of identity and roots. Major cartel figures invested heavily in ranches that served as staging grounds and connections to a narrative of the self-made man of the land. The cartel also functioned as an economic engine and social welfare provider in its home territory. In communities where poppy cultivation was the primary economic activity, the cartel provided stability, employment, dispute resolution, and a rough order that the state never provided.

Stories circulated of Guzmán appearing in rural villages to distribute cash and mediate disputes. Whether literally true or mythological, these stories reflected a genuine dynamic: the cartel as patron and protector in places where the government was absent. Guzmán was recaptured by Mexican Marines in February 2014. He was held at the Altiplano maximum security prison, and within seventeen months, he escaped again through a tunnel that ran approximately one and a half kilometers from a construction site to a hole cut through the floor of his shower room.

The tunnel had electricity, ventilation, and a small rail system with a motorcycle. The escape made front pages around the world. Guzmán was recaptured a third time in January 2016, extradited to the United States in January 2017, and convicted in February 2019 in a federal trial in Brooklyn. More than fifty witnesses testified, including former associates who described delivering suitcases of cash to Mexican government officials on Guzmán’s behalf, the scale of cocaine shipments measured in aircraft loads, and a methodical, patient, cold-blooded executive who had built a criminal enterprise intended to last.

Then came October 17, 2019. Mexican security forces attempted to arrest Ovidio Guzmán López, one of El Chapo’s sons, at a house in Culiacán. Within hours, armed cartel members flooded the streets. Convoys blocked major roads, gunfights erupted across the city, and soldiers were captured and used as bargaining chips.

Facing the prospect of a full-scale urban battle, the Mexican government released Ovidio Guzmán and stood down. The cartel had faced down the Mexican state in broad daylight in a major city and won. The event became known as El Culiacanazo. The Sinaloa cartel did not collapse when Guzmán was arrested.

It had been for years a federated structure with significant operational autonomy at the regional level. The man who co-founded the cartel alongside Guzmán was Ismael Zambada García, known as El Mayo. Where Chapo was celebrated, El Mayo was invisible. Born in 1948, he spent decades building his side of the organization with a focus on institutional relationships, financial connections, and political contacts.

He avoided public displays of wealth, invested heavily in legitimate businesses, and survived through the entire arc of the drug war until July 2024, when he was brought to the United States under circumstances that immediately became one of the most sensational and disputed stories in the history of Mexican organized crime. On July 25, 2024, El Mayo Zambada was arrested in New Mexico after arriving on a private plane. Reporting suggested he had been lured or deceived onto the plane by Joaquín Guzmán López, El Chapo’s son, who then cooperated with American authorities. The arrest touched off a period of internal conflict among the most violent in the organization’s history.

The cartel fractured into two major factions: those loyal to the Zambada family, known as Los Mayos, and those aligned with the Guzmán family, known as Los Chapitos. Journalists in Sinaloa described gun battles in the streets of Culiacán and the displacement of civilian communities. The modern Sinaloa cartel is best understood not as a single hierarchical organization but as a network of semiautonomous factions that share a common origin and certain operational infrastructure but compete as much as they cooperate. This model is more resilient in some respects, because removing any single node does not bring down the network.

But the period of fracture produced a level of violence that affected civilian populations in ways that contradicted the cartel’s historical self-presentation as a protective force. When internal conflict erupts, the rough peace breaks down, and communities that had come to rely on it are caught between factions. The cartel also became a global cultural phenomenon. Narcos: Mexico brought a version of these events to tens of millions of viewers.

Guzmán’s biography, escapes, tunnels, and meeting with actor Sean Penn generated celebrity coverage unprecedented for a criminal figure. Social media accelerated this, with Instagram accounts linked to cartel figures accumulating millions of followers who admired images of wealth and power. The people who paid the highest price for the empire were almost never those at the top. They were the farmers who grew the poppies under conditions of coercion and debt, the migrants taxed for using cartel-controlled roads, the journalists who covered the organization and paid with their lives, and the community members caught in crossfire during territorial disputes.

The empire was real, the money was real, the power was real, but the cost was distributed almost entirely downward. While the arrests of El Chapo and El Mayo represented genuine law enforcement victories, they did not represent the end of the empire those men built. The cartel is not finished. The conditions that produced it have not disappeared: the poverty of the Golden Triangle, the demand for drugs, the institutional weaknesses of the Mexican state, and the cultural infrastructure that provides cover for trafficking organizations.

The empire continues, managed by different hands, structured differently, but rooted in the same geography and the same fundamental economics that created it in the first place. The story of the Sinaloa cartel is not finished being written.
