The Slim Dynasty: When A Middle Eastern Family Owns Mexico

In 1902, a 14-year-old Maronite Christian boy named Khalil Salim Haddad Aglamaz stepped off a steamship onto the dock at the Mexican port of Veracruz, alone, speaking not a single word of Spanish, carrying nothing but the instructions his mother had given him before she sent him out of the Ottoman Empire forever. His mother had sent him away to keep him out of the Ottoman army. His four older brothers were already in Tampico, 300 miles up the Gulf coast, working inside the Lebanese trading community that had been quietly assembling itself across the Mexican Caribbean for the previous decade. Khalil Salim Haddad Aglamaz changed his name to Julián Slim Haddad to make it pronounceable to Mexican customers, learned Spanish inside his brothers' Tampico market stalls, moved to Mexico City in 1904, opened a dry goods store on the central commercial corridor of the Mexican capital, named it La Estrella de Oriente, and built it into one of the most successful Lebanese-Mexican commercial operations of the early 20th century. He died in 1953, leaving behind a 13-year-old fifth child named Carlos Slim Helú. That 13-year-old would grow up to become the richest person on Earth from 2010 through 2013. In this in-depth episode of Old Money Luxury, we trace four generations of the Slim dynasty — from a Maronite teenager fleeing Ottoman conscription, to a Mexico City dry goods store, to a 1982 debt-crisis bet that swallowed a country, to the $125 billion telecommunications empire ordinary Mexicans now simply call Slimlandia. ------------------- Gain FREE access to secret full-length documentaries on wealthy families "too scandalous for YouTube" by joining our newsletter: https://www.substack.com/@oldmoneyluxury ------------------- We open on the Slim family today — an aggregate net worth of approximately $125 billion, controlling positions in Grupo Carso, América Móvil, Telmex, and Grupo Financiero Inbursa, and a private commercial footprint that as of the 2026 Forbes Billionaires List equals roughly 6.7 percent of Mexico's entire gross domestic product. We trace the family's ancestral origins in the Mount Lebanon region of the late Ottoman Empire — the Maronite Christian community, the merchant lineages, and the pressures that pushed one generation of young men out of Beirut and into the port cities of the Caribbean between 1890 and 1914. We follow Julián Slim Haddad through his early life in Mexico — the Tampico apprenticeship inside his older brothers' market stalls, the 1904 opening of La Estrella de Oriente on the central commercial corridor of Mexico City, the marriage to Linda Helú, and the household discipline he built around a set of handwritten ledgers that would outlive him by seven decades. We watch Julián and Linda raise a family of six on a set of operating principles that would become the entire mental infrastructure of the next generation — the ledger discipline, the pricing discipline, the anti-debt discipline, and the reinvestment discipline that Carlos Slim Helú learned as a boy sitting on the floor of the family store. We reconstruct the first great crisis of the arc — the 1953 death of Julián when Carlos was 13, the family holding together under Linda's stewardship, and the boy who by 15 was already tracking his personal spending in a notebook and by 17 had made his first documented investment in a Banco Nacional de México bond. We trace Carlos Slim's building years — the engineering degree at UNAM, the marriage to Soumaya Domit, the founding of Inversora Bursátil in 1965, the Grupo Galas construction acquisition in 1966, and the disciplined accumulation of small industrial companies through the 1970s under an operating theory that markets would eventually reprice everything he was buying. We follow the second-generation collision with history — the 1982 Mexican peso devaluation, the Herzog default, the collapse of the Mexican industrial sector, and the moment Carlos Slim spent every liquid peso the family had accumulated buying entire Mexican industrial companies at prices no international investor was willing to pay. We reconstruct the 1990 privatization of Teléfonos de México — the winning consortium of Grupo Carso, France Télécom, and Southwestern Bell, the operating control that ran through Slim's hand, the 20-year regulatory shield that came with the deal, and the transformation of a state telephone monopoly into a private continental empire. We trace the family's peak-power decade — América Móvil's expansion across 18 countries, the 2010-2013 seasons at the top of the Forbes list, the 2015 stake in The New York Times, and the moment ordinary Mexicans stopped calling their country Mexico and started calling it Slimlandia.
