The War of the Spanish Succession

It is the year 1700, and in the Alcázar of Madrid, the atmosphere is suffocating. Charles II, nicknamed “the Bewitched”, lies dying without having managed to father an heir. It is not just the death of a man; it is the collapse of a dynasty, that of the Habsburgs, which has ruled half the world for two centuries. What lies ahead is not a simple transition, but a shockwave that will change the map of Europe and the identity of the peninsula. If you are wondering what the War of the Spanish Succession is, the short answer is that it was the conflict that decided who got to keep the enormous pie of the Spanish Empire, but the long answer is much more fascinating and complex.

That power vacuum not only triggered the ambitions of local nobles, but also put Versailles and Vienna on alert. The king’s final will designated Philip of Anjou, grandson of Louis XIV of France, as his successor. But in international politics, gifts usually come with a catch. By crowning a Bourbon in Madrid, France would become an unbeatable superpower, something that England and the Netherlands were not willing to allow.

A will and two candidates

To understand this summary of the War of the Spanish Succession, one must look at the two men who personified the dispute. Philip of Anjou represented the French model: absolutism, centralization, and a modern but relentless administration. Opposite him was Archduke Charles of Austria, who defended the continuity of the model of the Habsburgs, where each kingdom maintained its own laws and privileges.

This was not just a diplomatic battle. When Philip V entered Madrid, half of Europe began to tremble. The Grand Alliance of The Hague was formed, a bloc led by England, Austria, and the Netherlands, with a clear objective, which was to prevent the French fleur-de-lis and the Spanish crown from merging into a single hand. Thus, what began as a bedchamber crisis ended up being a world war “avant la lettre”.

The two sides and their visions of the State

Candidate	Dynasty	Main support	Model of government
Philip V	Bourbon	France, Crown of Castile	Centralization and unified command
Archduke Charles	Habsburg	Austria, England, Crown of Aragon	Pactism and respect for regional privileges

Causes and consequences of the War of the Spanish Succession

If we scratch the surface, the causes and consequences of the War of the Spanish Succession reveal a total paradigm shift. The causes were not only biological (the sterility of Charles II), but deeply economic. England wanted to break Spain’s commercial monopoly with America. France, for its part, needed Spanish resources to suffocate its continental rivals.

The peninsula fractured. Castile, in general, remained loyal to Philip V, seeing in him the possibility of a regeneration after years of decline. On the other hand, the Crown of Aragon (Catalonia, Aragon, Valencia, and the Balearic Islands) ended up supporting Archduke Charles. Why? Not out of personal sympathy, but out of fear. French absolutism was famous for crushing any local autonomy, and the Aragonese did not want to lose their centuries-old institutions.

An unexpected turn in the consequences

What came after 1713 was not just a change of king. The main international consequence was the end of Spanish hegemony in Europe. Spain ceased to be a European empire and became “only” an Atlantic power. Internally, the country underwent a traumatic transformation with its unification under a single command, eliminating the legislative diversity that had characterized the Hispanic monarchy since the Catholic Monarchs.

Stages of the War of the Spanish Succession

We cannot speak of a linear conflict. The stages of the War of the Spanish Succession are clearly divided between what was happening outside our borders and what was occurring in the mud of the peninsular trenches.

1. The international outbreak (1701-1705): The early years were a give-and-take in the Low Countries and Italy. In 1704, an event would mark Spanish history to this day: an Anglo-Dutch fleet captured Gibraltar. What was meant to be a temporary base to support the Archduke ended up becoming an open wound in Spanish geography.
2. The civil war (1705-1710): The conflict fully entered the peninsula. Archduke Charles even managed to enter Madrid on two occasions, but failed to hold the city due to the hostility of a largely pro-Bourbon population. In 1707, the Battle of Almansa changed the course: Philip V’s victory opened the doors of Valencia and Aragon to him.
3. The diplomatic outcome (1711-1714): Sometimes, death is the best diplomat. The Emperor of Austria died, and Archduke Charles inherited the imperial throne. Suddenly, England was no longer pleased with the idea of Charles being King of Spain and Emperor of Austria at the same time. That would mean returning to the days of Charles V. London decided it was time to negotiate peace.

The Battle of Almansa and the beginning of the end

If there is one moment that defines the fate of the peripheral kingdoms, it is April 25, 1707. Almansa was not merely a military victory; it was the legal pretext that Philip V needed. Considering that Valencia and Aragon had rebelled, the king used the “right of conquest” to abolish their regional privileges.

That was a warning to all. Resistance then concentrated in Catalonia, which held out until the very last breath. The siege of Barcelona in 1714 is, perhaps, the rawest episode of the war. A city bombarded and abandoned by its English allies, who preferred to negotiate commercial benefits rather than defend the Archduke’s cause.

The distribution of territories after the conflict

Lost territory	New owner	Strategic reason
Gibraltar and Menorca	Great Britain	Control of the Mediterranean
Low Countries and Milan	Austria	Compensation for the lost crown
Sicily	Savoy	Strengthening of the House of Savoy
American territories	España (Borbones)	Philip V retained the bulk of the Empire

The Treaty of Utrecht, the price of the crown

The question of who won the War of the Spanish Succession is a trick question. If you look at the throne, Philip V won. If you look at global power, Great Britain won. The Treaty of Utrecht (1713) was the document that put the new world order in black and white.

España tuvo que ceder mucho para que Felipe fuera reconocido. No solo perdió sus posesiones en Italia y Flandes, sino que tuvo que abrir una grieta en su monopolio americano. Se concedió a los ingleses el «asiento de negros» (el permiso para vender esclavos en las Indias) y el «navío de permiso» (un barco de 500 toneladas que podía comerciar anualmente con las colonias). Fue el inicio del fin del aislamiento comercial español.

The Nueva Planta Decrees and the new Spain

With the war over, Philip V lost no time. The design of the new State was embodied in the Nueva Planta Decrees. What did this mean in practice?

• Abolition of local laws (fueros): Aragon, Valencia, Majorca, and Catalonia lost their own laws.
• Centralization: The intendancy system was imposed, and the figure of the captain general was created to govern the provinces.
• Language: Castilian Spanish became the mandatory language in administration and justice.

It was radical surgery. Spain went from being a confederation of kingdoms united under a single crown to a centralized state. Many see in this the seeds of contemporary territorial conflicts, while others view it as a necessary step toward 18th-century modernization and administrative efficiency.

Who actually won the War of the Spanish Succession?

If we make a final assessment, the outcome is bittersweet. Philip V remained in the Royal Palace of Madrid, yes, but he did so at the expense of dismembering his predecessors’ European empire. Spain became a second-tier power on the continent, although it experienced a curious internal recovery.

Britain was the winner in the shadows. It kept Gibraltar, Menorca (which Spain would later recover), and, above all, the keys to Atlantic trade. Austria, for its part, took the Italian territories, slaking its thirst for expansion. In short, the war served to establish a balance of power in Europe where no single nation was too strong, at the cost of Spain ceasing to be the giant it once was.

The legacy of a 14-year conflict

The War of the Spanish Succession was not an event that can be dismissed in two paragraphs. Its legacy lives on in the architecture of our cities, the structure of our government ministries, and today’s political debate. It was the moment when Spain decided (or was forced to decide) that its future lay in centralization and French influence, leaving behind the polysynodal model of the Habsburgs.

Today, more than three hundred years later, the echoes of 1714 are still present. Whether through the persistence of local civil law (derecho foral) in some regions or the presence of a British flag on the Rock, the War of the Succession is a living lesson in how the interests of great powers can redraw the destiny of an entire country.
