The Spanish Empire controlled much of Latin America for over 300 years and was one of the largest empires ever. It spanned from the southern tip of Patagonia in South America to the Southwest of the United States. By the late 18th century, its colonial territory covered 13.7 million square kilometers.
However, between 1808 and 1826, the Spanish imperial regime in Latin America fell apart, and its territories were divided into several independent states. How did such a colossal empire fall after centuries of dominance?
How Deep Social Inequality Fueled Latin American Independence

One of the main causes of the empire’s collapse was widespread discontent among the masses. The Spanish Empire upheld a strict social caste system that valued class over wealth or merit. For hundreds of years, Spain had segregated its people into these social categories.
On top were the Peninsulares born in Spain. They occupied the highest offices of administration, including the Church and the military. Next were the Criollos or Creoles, who were of pure Spanish blood born in the New World. While the Creoles owned the majority of the land and had substantial wealth, they were barred from reaching the highest offices of the land. By the 1700s, the wealthy, educated Criollos felt no personal loyalty to a distant monarch that held them back from power, turning many of them into determined revolutionaries ready to fight for self-rule.
The Mercantilist Greed That Suffocated Imperial Commerce

Although the masses were separated by class, all were angry at economic suffocation. At the time, Spain operated under tight mercantilist policies, such that its colonies were expected to ship cheap raw materials and precious metals to Spain and buy manufactured goods from the mother country. The system helped to ensure that Spain maintained a positive trade balance and accumulated gold and silver wealth. It was regulated by the Casa de Contratación or House of Trade, which was founded in Seville in 1503.
Spain was also keen to prohibit trade between Latin American colonies and any other foreign country such as Great Britain or France, and sometimes even between the colonies themselves. During the 1780s, the Crown under King Charles III began to demand more from its colonies through the Bourbon Reforms. While the strategy increased revenue for Spain, it alienated local colonial elites like the Criollos. What was initially seen as protection from Spain was now seen as economic restriction.
The Power Vacuum That Shattered Spain’s Hold on the Americas

The first immediate spark for the revolution originated across the Atlantic Ocean when Napoleon Bonaparte of France invaded Spain’s holdings in the Iberian Peninsula in 1807, and then deposed the King of Spain, Charles IV, along with his son and heir Ferdinand VII, in 1808. He put his brother Joseph Bonaparte on the throne. As a result of the change, Spanish American colonies were suddenly faced with a constitutional crisis regarding who had legitimate rule over them.
In the absence of a king, local governing bodies known as juntas quickly sprang up in cities such as Caracas, Buenos Aires, and Santiago in 1810. Many of them claimed that they ruled under the authority of Ferdinand VII, while others began to explore their independence. The push for colonial independence, in particular, began in earnest when the priest Miguel Hidalgo y Costilla rang the bell of his church in Dolores, Mexico, on September 16, 1810, initiating Mexico’s long war for independence.
The Bold Military Campaigns That Decisively Defeated Spanish Rule

The push for independence was driven on the battlefield by a collective of military leaders influenced by Enlightenment ideals. One of those great liberators was Simón Bolívar, also known as The Liberator. He dreamt of a united South America and personally led military campaigns that resulted in the independence of Venezuela, Colombia, and Ecuador, while also inspiring the political movement in Panama. Further south, General José de San Martín put together the Army of the Andes and crossed the mountains into Chile in 1817, successfully liberating the country before pushing forward to Peru.
Having been ousted by Napoleon, King Ferdinand VII reclaimed the throne in 1814 and vowed to return Spain to absolute monarchy, while ignoring the liberal Spanish Constitution of 1812. This aggressive course of action alienated even the moderate royalists in the Americas. Spanish military power in South America suffered a final blow at the Battle of Ayacucho on December 9, 1824, where patriot forces under General Antonio José de Sucre defeated the royalist army led by Viceroy José de la Serna. Although facing a somewhat larger force, the enthusiastic patriot forces achieved a decisive victory.

The last Spanish stronghold on mainland South America fell in 1826 when Spain lost its final garrisons at Chiloé in Chile and Callao in Peru, ending more than 300 years of Spanish imperialism in the region. Though Spain tried to maintain power in Europe, it never recovered its former hegemony as the preeminent global power that it had been.
