Philip IV of Spain: What Most People Get Wrong About the Planet King

Philip IV of Spain: What Most People Get Wrong About the Planet King

He stood so still that people thought he was a statue. Seriously. Philip IV of Spain had this weird, almost supernatural ability to remain perfectly motionless during public appearances. To the crowds in 17th-century Madrid, he was the "Planet King"—the fixed center around which a global empire revolved. But if you look behind the heavy velvet curtains of the Alcázar palace, the man was a mess of contradictions.

He was arguably the greatest art patron in European history, the guy who "discovered" Velázquez. Yet, he presided over a slow-motion car crash of an empire. He was deeply, almost neurotically religious, but he couldn't stop having affairs, eventually fathering somewhere around 30 illegitimate kids.

Basically, Philip IV is the ultimate "it’s complicated" figure of the Spanish Golden Age.

The King Who Never Smiled (Except Three Times)

There’s a legend that Philip IV only laughed three times in his entire public life. Whether that’s literally true or just great PR for his "royal dignity," it tells you everything about the vibe he wanted to project. He was coached from a young age by his right-hand man, the Count-Duke of Olivares, to be the model of Baroque kingship: somber, pious, and utterly untouchable.

But that rigid exterior was a mask.

In private, he was obsessed with the theater. He’d sneak out to literary salons called "academies" to hear poets roast each other. He was a man of intense, almost frantic energy when it came to his hobbies, which included hunting and, well, women.

The Olivares Factor

You can't talk about Philip IV without talking about Gaspar de Guzmán, the Count-Duke of Olivares. If Philip was the face of the brand, Olivares was the CEO working 20-hour days in a back office.

  • The Vision: Olivares wanted to make Spain great again (literally). He pushed for the "Union of Arms," trying to get all the different parts of the Spanish empire to pitch in for the military.
  • The Reality: People hated it. Portugal and Catalonia eventually revolted because they didn't want to pay for Castile's wars.
  • The Fall: By 1643, the pressure was too much. Philip finally fired his lifelong friend and mentor, who died shortly after, basically from a broken heart and a lost mind.

Why the Art Matters More Than the Wars

Most kings are remembered for the land they conquered. Philip IV is remembered for the canvases he bought. If you’ve ever stood in front of Las Meninas at the Prado Museum, you’re looking at the peak of Philip’s legacy.

He didn't just hire Diego Velázquez; he befriended him. He made Velázquez a knight, which was a huge deal back then because painters were seen as manual laborers, not "gentlemen." Philip saw something in Velázquez that mirrored his own melancholy.

He also went on a shopping spree across Europe. He bought up Peter Paul Rubens’ estate and commissioned works from Titian and Raphael. He turned the Buen Retiro Palace into a massive art gallery. While the Spanish treasury was literally going bankrupt—multiple times—Philip was still finding the cash for a new masterpiece.

Was it irresponsible? Probably.
Is it the reason we still care about him today? Absolutely.

The Inbreeding Problem and the End of the Line

We have to talk about the family tree. In the 17th century, the Habsburgs treated marriage like a game of musical chairs where the chairs never left the family. Philip’s first wife was Elisabeth of France. They had several kids, but only one son, Balthasar Charles, who was supposed to be the savior of the dynasty.

Then Balthasar died of smallpox at 16.

Desperate for an heir, a 44-year-old Philip married his 14-year-old niece, Mariana of Austria. If that sounds icky, it was. This is where the famous "Habsburg Jaw" became a genetic disaster. Their only surviving son was Charles II, a boy so physically and mentally fragile he could barely chew his own food.

Philip knew the empire was slipping. You can see it in his later portraits. The eyes are heavier, the face is sagging, and he looks like a man who knows he’s the penultimate chapter of a dying story.

What You Should Do Next

If you want to really "get" Philip IV, you have to look at the world he built, not just the dates of his reign. History isn't just a list of wars; it's the stuff that survives them.

  1. Visit the Prado (Virtually or In-Person): Look at the portraits Velázquez painted of Philip over 40 years. You can literally watch the king age and the "statue" begin to crack.
  2. Read "The Count-Duke of Olivares" by J.H. Elliott: If you want the gritty political details of why Spain went broke, this is the gold standard. Elliott is the expert who basically redefined how we see this era.
  3. Explore the Buen Retiro: While much of the palace is gone, the gardens remain in Madrid. It gives you a sense of the sheer scale of Philip’s "theatrical" life.

Philip IV wasn't a great general or a brilliant economist. He was a flawed, deeply human man who tried to hold onto a crumbling world through sheer willpower and a lot of oil paint. He proves that even if you lose the war, you can still win the culture.
