The flag would be finally declared the national flag by the Congress of Tucumán on July 20, 1816, shortly after the declaration of independence. The proposal was made by the deputy Juan José Paso and the text written by the deputy of Charcas, José Serrano. On February 25, 1818, the Congress (now working at Buenos Aires) included the Sun of May in the war flag, after the proposal of deputy Chorroarín. The sun was copied after the one that the first Argentine coin featured in 1813. It was subsequently decided to keep it as part of the regular flag afterwards, and thus the sun no longer represents war.
