National Sovereignty Day is an Argentine holiday observed on every fourth Monday (or ideally, the closest one to November 20) in November — this year on November 24. Like other holidays celebrating battles, National Sovereignty Day in Argentina marks the anniversary of the Battle of Vuelta de Obligado — but there’s a twist to it. The Argentine army did not win the battle. Yet the day is nationally celebrated as a public holiday with citizens taking pride in their country’s historic defeat, which went on to become their triumph. They bask in the glory of the statement — “lose the battle but win the war.”

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.
