Why Argentina celebrates ‘Nueve de Julio’ as its independence day

Argentina celebrates 9 July as its independence day, known locally as “Nueve de Julio.” The date marks 9 July 1816, when the Congress of Tucumán formally declared the country’s independence from Spanish colonial rule, under the name of the United Provinces of the Río de la Plata.

The declaration came after a decade of upheaval that began in 1806, when local militia in Buenos Aires repelled British attacks with little support from Spain, and continued as Napoleon Bonaparte’s occupation of Spain and overthrow of King Ferdinand VII plunged the Spanish crown into crisis. The independence movement, led by figures including José de San Martín and Manuel Belgrano, culminated in the declaration signed at the house of Francisca Bazán de Laguna in Tucumán.

Nueve de Julio is now a federal holiday in Argentina, marked with fireworks, military parades, official speeches and family gatherings across the country. It remains one of the most significant dates on the Argentine calendar, alongside 25 May, which marks the 1810 May Revolution that set the independence process in motion.

Argentina is not the only country with a major national anniversary falling on 9 July. South Sudan marks its own independence day on the same date, having formally separated from Sudan on 9 July 2011 after a referendum in which 98.8 per cent of voters backed independence.

The coincidence means 9 July carries distinct significance on two different continents — a date of nation-founding in both South America and East Africa, separated by nearly two centuries.
