The Decline of Spanish Imperial Power in the 17th Century

The Spanish Monarchy could not maintain its dominance over England, France, and the Netherlands. The royal treasury (Hacienda) was deeply in debt, and resources from the Americas were not effectively utilized. A few privileged social groups dominated society, living off land rents and failing to stimulate a productive economy.

Internal Weaknesses and Economic Decline

• Monarchs' Disinterest and Delegation

  Monarchs showed little interest in governance, prioritizing personal income and prestige. They dedicated their time to hunting, palace receptions, and other leisure activities. They delegated their functions to their validos (royal favorites), who acted as heads of government.

• Corruption and Inefficient Administration

  Many validos exploited their power for personal gain, leading to increased corruption and inefficient administration. Favorites accumulated so much power that the court became a web of intrigue. The validos' governments often sold positions in state administration and honors for lucrative personal gain.

• Economic Crisis and Bankruptcies

  The 17th-century economy suffered a significant decline. A rise in prices led to widespread poverty, American mines began to deplete their precious metals, and fiscal measures failed to generate sufficient revenue. The crown declared bankruptcy multiple times.

Major Conflicts and Territorial Losses

• The Thirty Years' War (1618-1648)

  During the reign of Philip III, agreements were made with England, and the Twelve Years' Truce (1609) was signed in the Netherlands. The reign of Philip IV coincided with the Thirty Years' War (1618-1648), a major religious conflict and a struggle for dominance in Europe. German Protestant princes confronted the Catholic Emperor of Austria.

  The Count-Duke of Olivares advocated for Spain's entry into the war to support Austria, aiming to maintain Habsburg dominance in Europe and limit France's growing influence. The war ended with the defeat of Imperial and Spanish troops. The Peace of Westphalia (1648) recognized the independence of the Northern Netherlands from the Spanish Crown and marked a significant decline for the Spanish Empire in Europe.

• Revolts of 1640

  Increased fiscal pressure and the 'Union of Arms' policy led to widespread crisis, sparking major revolts:

  • Portugal: A rebellion driven by leaders demanding independence proclaimed the Duke of Braganza as King John IV. Portugal received support from France and England, enemies of the Spanish Monarchy. In 1668, Spain formally recognized Portuguese independence.
  • Catalonia: The imposition of new taxes and the quartering of troops provoked a peasant uprising. Catalonia briefly placed itself under the sovereignty of the King of France. The armed insurrection lasted until 1652, when Philip IV's army retook the city of Barcelona.

• Emergence of French Dominance

  Clashes between Spain and France continued. The Peace of the Pyrenees (1659) saw the Spanish Empire lose territories in the Netherlands, on the Rhine, and Roussillon and Cerdanya. During Charles II's reign, further wars with France occurred. The Treaty of Nijmegen resulted in France annexing Franche-Comté and other Spanish territories. These agreements marked the beginning of French dominance in Europe and the eclipse of Spanish power.
