Today, our country commemorates Argentine Naval Prefecture Day, a date that honors the legacy of one of the country’s oldest and most prestigious institutions, which for 216 years has been responsible for ensuring the safety of waterways, protecting natural resources, and strengthening national sovereignty.

The celebration commemorates June 30th, 1810, when Mariano Moreno, then Secretary of Government and War of the First Junta, appointed Martín Jacobo Thompson as the first Port Captain of the Río de la Plata. That decree marked the birth of the General Port Captaincy, the predecessor of today’s Argentine Naval Prefecture.

Throughout its history, the institution has undergone a process of consolidation and modernization. In 1882, it adopted the name “Maritime Prefecture,” and in 1969, it was renamed the “Argentine Naval Prefecture”—a name it retains today and which more accurately reflects the scope of its functions.

Under the jurisdiction of the Ministry of National Security, the force serves as the maritime security police and plays a fundamental role in maintaining public order in national waters and ports. In addition, it carries out tasks related to the protection of the aquatic environment, maritime safety, and the enforcement of judicial, immigration, customs, health, and fisheries regulations.

On another anniversary of its founding, Argentine Naval Prefecture Day provides an opportunity to recognize the commitment, dedication to service, and professionalism of the members of this force, whose daily work helps ensure the safety of waterways, preserve natural resources, and reaffirm Argentina’s sovereignty over its maritime and riverine territories.
