National Sovereignty Day

November 20, Wednesday

The National Sovereignty Day is a national public holiday of Argentina, celebrated during November 20. It commemorates the Battle of Vuelta de Obligado, when a small Argentine army stood against an Anglo-French navy that broke into the Paraná River on November 20, 1845, against the will of the Argentine Confederation. Although the battle itself ended with an Argentine defeat, the losses of Britain and France in the whole military campaign were so high that both countries were forced to the bargaining table and signed a treaty with Juan Manuel de Rosas. The day was enacted as a national observance in 1974, following a request from the revisionist historian José María Rosa, and promoted into a national holiday in 2010.
