July 9 across history: From Tucumán’s independence declaration to Juba’s new flag

9 July connects two moments of nation-building nearly two centuries apart: the Congress of Tucumán’s 1816 declaration of Argentine independence, and the raising of South Sudan’s new flag in Juba in 2011.

In Tucumán, Argentina, delegates gathered on 9 July 1816 to declare independence from Spanish colonial rule, under the name of the United Provinces of the Río de la Plata. The declaration, signed at the house of Francisca Bazán de Laguna, followed years of unrest that included the repulsion of British attacks on Buenos Aires in 1806 and the crisis triggered by Napoleon Bonaparte’s occupation of Spain. The date, “Nueve de Julio,” remains a federal holiday in Argentina today.

In Juba, South Sudan, hundreds of thousands of people gathered on 9 July 2011 to celebrate as the country’s new flag was raised for the first time, marking its formal separation from Sudan after a January 2011 referendum in which 98.8 per cent of voters backed independence. South Sudan became Africa’s 54th independent state and joined the United Nations on 14 July 2011.

The date also holds significance in North America. Canada observes 9 July as Nunavut Day, marking the 1993 Nunavut Land Claims Agreement, while the United States marks 9 July 1868 as the date the 14th Amendment to its Constitution was ratified, granting citizenship and equal protection under the law to formerly enslaved people.

Taken together, the events reflect how a single date on the calendar can mark distinct chapters of national and constitutional history on different continents.
