|The Cabildo at Plaza de Mayo|
The May 25 national holiday in Argentina commemorates the events that culminated in the country’s May Revolution, which in 1810 was the prelude to Argentina’s eventual independence from Spain.
Towards the end of the 18th century revolution was doing the international rounds. Independence for what became the US demonstrated that the colonies in the Americas could go it alone, and the French Revolution in 1789 encouraged many to question the concept of the divine rights of kings.
The Spanish monarchy of course was not so convinced by the liberal and anti-nobility ideas coming out of France, and despite actually aiding the thirteen North American colonies who won freedom from British rule in 1776, was not disposed to relinquishing control over its own colonies in the Americas.
