History of National Flag Day in Argentina

The Argentine flag was created by Manuel Belgrano during the struggle for independence in the early nineteenth century. On February 27, 1812, Belgrano had a light blue and white flag raised for the first time on the banks of the Paraná River, in what is now Rosario. The colors were connected with the national cockade already in use by patriots of the period. Argentina’s Congress later gave official recognition to the light blue and white flag after independence, and the Sun of May was added to the central white stripe in 1818.

National Flag Day itself was established by Argentina’s National Congress in 1938 through Law 12.361, which set June 20 as the day to honor the flag and remember Belgrano. The date marks his death in Buenos Aires in 1820, so the observance links the national symbol with the life of the person most closely associated with its creation. Later rules confirmed June 20 as an immovable commemoration, keeping it tied to the anniversary rather than moving it for convenience. Today, the day is officially known in Spanish as the “Passing to Immortality of General Manuel Belgrano,” while many people also refer to it simply as Flag Day.
