The wars of Spanish-American independence were a series of military campaigns that took place in the Americas between 1809 and 1825, which resulted in the creation of more than a dozen republics in the territories that had previously been part of the Hispanic monarchy. Triggered in the short term by the Napoleonic invasion of the Spanish peninsula in 1808, there were more deep-seated reasons, however, that led to the collapse of an empire that had existed for three hundred years. Classic historiography has stressed the importance of the Bourbon Reforms that brought to the fore the contradictions within the Hispanic monarchy and gave rise to a sense of proto-nationalism. These interpretations have given much importance to the role of the Enlightenment and the fear brought by possible social revolution. Some authors consider that these wars were the result of the Americans’ long-held contempt for Europeans. These views consider that struggle for liberation had begun much earlier, possibly as far back as the 1780s, inspired by the American and French Revolutions. More recent historiography has highlighted the war that engulfed Spain itself between 1808 and 1814 as the crucial event that led to fighting in the Americas. This event is seen as not just the trigger for the events to unfold, unleashing conflicts that had been simmering for much longer, but what shook to the ground the archaic but surprisingly durable composite Hispanic monarchy. This article will discuss the main events that caused the wars, the moments each national historiography has identified as the ones linked to the independence of their particular region, as well as the events themselves. It begins by looking at the historical antecedents, including the Bourbon Reforms, the American, French, and Haitian revolutions, and at the Napoleonic invasion of the Spanish peninsula. It then discusses the creation of juntas in the Americas and how the confrontation between different jurisdictions resulted in war. The article discusses who were the people involved in the wars and the main events that took place.
