Manuel Belgrano, a prominent leader in the Argentine War of Independence, raised the Flag of Argentina for the first time in the city of Rosario. This event symbolized a critical turning point for the revolutionary movement against Spanish colonial rule. The flag, which consisted of light blue and white horizontal stripes, was inspired by the colors of the Virgin Mary and was a source of inspiration for the burgeoning sense of national identity among the people of the United Provinces of the Río de la Plata. Belgrano's actions were not only about raising a flag; they represented a call for unity and resistance against oppression, galvanizing support for the cause.At the ceremony, Belgrano addressed the gathered crowd, reinforcing their commitment to fight for independence and sovereignty. This moment contributed to fostering a collective spirit among the diverse inhabitants of the region. The event took place just a year before the May Revolution, which would further escalate the fight for independence and lead to the formal declaration of autonomy from Spanish rule. This act of raising the flag is commemorated in Argentine history, serving as a symbol of aspiration for freedom and self-determination.The significance of this event extends beyond its immediate context; it underscores Belgrano's role as a patriot and strategist in the independence movement. The flag raised that day would later become a symbol of Argentine nationalism, used in multiple military campaigns against Spanish forces. Today, the date is celebrated in Argentina as a moment that encapsulates the spirit of independence and national pride that characterized the early 19th century struggles.
