The creation of the flag of Argentina is generally attributed to Manuel Belgrano, who made a flag at the beginning of 1812 using the colors white and light blue according to those of the already official rosette, but it is unknown what the intensity of the light blue color was and what it was its design —which varies in the number of two to three stripes and in its horizontal or vertical location— since the official flag finally adopted is the smallest one that was established by the Congress of Tucumán —as a patriotic symbol of the United Provinces del Río de la Plata—through the law of July 26, 1816, divided it into three horizontal stripes of equal size, the upper and lower ones light blue and the central one white, to which el Sol de mayo was added , established by the law of February 25, 1818.
