History of National Sovereignty Day Argentina
The Battle of Vuelta de Obligado took place on November 20, 1845, when the Anglo-French navy invaded the Paraná River. As the Anglo-French navy went against the will of the Argentine Confederation, a small Argentine army decided to oppose it in a battle. Although the attacking forces emerged victorious on the battleground, the wounds of the fallen soldiers got the best of the enemy’s troops.
Britain and French armies suffered such heavy losses through the whole military campaign that they were forced to surrender on the bargaining table, requesting Juan Manuel de Rosas, the Governor of Buenos Aires, for a peace treaty — despite being victorious.
Consequently, a treaty was signed, marking the day as a historical win for the lost Argentine troops.
National Sovereignty Day is also remembered as a key event in Argentina’s historical calendar in which the country fought against the colonial powers and protected its regions from domination. Although November 20 was enacted as a national observance in 1974, the celebration of the fourth Monday only recently became a national holiday in 2010.
