Oil Expropriation Day

Oil Expropriation Day, or Día de la Expropiación Petrolera, is observed every year on March 18. It marks the historic moment in 1938 when President Lázaro Cárdenas announced the nationalization of Mexico's oil industry. At the time, most oil operations were controlled by foreign companies. The workers demanded better wages and conditions, and when talks failed, Cárdenas made the bold move to expropriate the oil resources in favor of the nation.

This decision led to the creation of PEMEX (Petróleos Mexicanos), the state-owned oil company. The move was seen as a powerful step toward economic independence and national pride. Although it faced international pressure, the Mexican people strongly supported it, even raising money to pay compensation. Today, March 18 is remembered as a key moment in Mexico's modern history and its struggle for energy sovereignty.
