Flag of Argentina: Who first hoisted the Argentine flag?

Flag of Argentina

The Argentinean flag is one of my favorites.

The flag of Argentina is horizontally striped celeste-white-celeste, often it includes including a highly symbolic central golden sun. Its width-to-length ratio varies: proportions of 1 to 2 and of 9 to 14 are commonly used on land, while the ratio 2 to 3 is used at sea.

I have read much information about this flag and it is most likely that the celeste-white-celeste stripes originated from the blue cockades worn by patriots 10 May 1810, when the Spanish viceroy in Buenos Aires yielded authority to the Buenos Aires Cabildo, and the uniforms worn by the Argentine militias in 1806 & 1807, when the British attacked Buenos Aires and were repelled. The celeste-white-celeste horizontally striped flag was first hoisted on February 12, 1812, by General Manuel Belgrano.

On July 9, 1816, Argentina, then part of the United Provinces of the Río de la Plata, the remnants of the old Viceroyalty of the Rio del la Plata, proclaimed its independence from Spain after the conference of Tucuman. However, it was not until February 25, 1818, that the golden 'Sun of May' was added to the center of the flag in reference to the events of 10 May 1810, when the sun supposedly broke through black clouds casting an amazing light on Buenos Aires as the porteños exiled the Spanish Viceroy who had shown unprecedented cowardice in fleeing two British invasions with his garrison.

At first there were struggles between those who wanted a strongly centralized Argentina and those who favored broad autonomy for individual provinces, many of which had their own flags and ruling classes of their own. This period saw many battles between the Unitarians and Federalists whose opposing colors of red and white eventually gave the color pink to la Casa Rosada, home of the Argentine executive branch. Finally, in 1860 definitive unification firmly established the celeste-white-celeste as the sole flag of Argentina. On August 16, 1985, after the end of Military rule, permission was granted to private citizens to fly the version that is famous throughout the world today, which incorporates the Sun of May in the centre, a right previously restricted to the government and military.
