Flag of Argentina in the context of Federal Pact

Manuel José Joaquín del Corazón de Jesús Belgrano (3 June 1770 – 20 June 1820), usually referred to as Manuel Belgrano (Spanish pronunciation: [maˈnwel βelˈɣɾano]), was an Argentine public servant, economist, lawyer, politician, journalist, and military leader. He took part in the Argentine Wars of Independence and designed what became the flag of Argentina. Argentines regard him as one of the main Founding Fathers of the country. He was also a supporter of free trade.

Belgrano was born in Buenos Aires, the fourth child of Italian businessman Domingo Belgrano y Peri and of María Josefa González Casero. He came into contact with the ideas of the Age of Enlightenment while at university in Spain around the time of the 1789 French Revolution. In 1794 he returned to the Viceroyalty of the Río de la Plata, where he became a notable member of the criollo population of Buenos Aires; he tried to promote some of the new political and economic ideals, but found severe resistance from local peninsulares. This rejection led him to work towards a greater autonomy for his country from the Spanish colonial regime. At first he unsuccessfully promoted the aspirations of Carlota Joaquina to become a regent ruler for the Viceroyalty during the period when the French imprisoned the Spanish King Ferdinand VII during the Peninsular War (1807–1814). Belgrano favoured the May Revolution, which removed the viceroy Baltasar Hidalgo de Cisneros from power on 25 May 1810. He was elected as a voting member of the Primera Junta that took power after the ouster.
