Meaning and symbolism
Documented symbolism
Decree 10302/1944 codifies the national symbols. The colors derive from the blue and white cockades distributed during the May Revolution of 1810.
The golden Sun of May (Sol de Mayo) commemorates the sun breaking through clouds on 25 May 1810 as the first patriotic government took office.
Common interpretations
Popular tradition views the colors as representing the sky and clouds, or the silver (argentum) of the Río de la Plata.
History and design evolution
The national flag of Argentina was created by General Manuel Belgrano, one of the foremost leaders of the Argentine War of Independence. During the military campaigns along the Paraná River near the city of Rosario, Belgrano realized that his revolutionary troops were wearing ribbons and emblems similar to those of the royalist forces, causing confusion on the battlefield. Belgrano had previously established the light blue and white Escarapela (cockade) of Argentina, which the First Triumvirate had approved in February 1812.
On February 27, 1812, on the banks of the Paraná River, Belgrano raised a new flag made of white and light blue silk for his troops to swear allegiance to the cause of Argentine independence. Although the cautious Triumvirate in Buenos Aires initially ordered Belgrano to suppress the flag out of diplomatic hesitation toward Spain, Belgrano had already carried it into the Army of the North, where it became beloved by the troops after decisive victories at Tucumán and Salta.
The Congress of Tucumán officially declared Argentine independence and formally adopted the Bandera Menor (the light blue and white triband) as the national flag on July 20, 1816. Two years later, on February 25, 1818, the Congress added the golden Sol de Mayo (Sun of May) with 32 alternating straight and wavy rays to the central white stripe to serve as the military war flag (Bandera Mayor). In 1985, Law 23.208 unified the design, granting all Argentine citizens the right to fly the flag bearing the Sun of May, and Presidential Decree 1650/2010 definitively codified its statutory 5:8 proportions, coordinates, and exact CIE color specifications.
