In 1979, Iran’s 2,500-year monarchy collapsed in 14 days.

The Shah of Iran, once the U.S.’s closest ally, was exiled.

An exiled cleric, Ruhollah Khomeini, returned.

And the Middle East hasn’t been the same since.

Here’s the story of how Iran’s Islamic Revolution shook the global order:Image
The fall of Iran’s monarchy wasn’t sudden.

It unraveled gradually, then all at once.

For decades, the U.S.-backed Shah of Iran tried to modernize the country at breakneck speed.

But he underestimated the power of religion, resentment, and revolution.
The Shah, Mohammad Reza Pahlavi, took the throne in 1941.

Educated in Switzerland, fluent in French, and a darling of the West, he dreamed of turning Iran into a modern empire.

Oil would fund it. U.S. weapons would protect it. And Westernization would define it. Image
But beneath the glittering surface of modernization, pressure was building.

His land reforms upended feudal structures.

His secular policies angered the clergy.

And his secret police (SAVAK) tortured dissenters.

Even veiling became a political flashpoint. Image
His fiercest opponent?

A quiet, austere cleric named Ruhollah Khomeini.

From exile, Khomeini wrote and preached of an Islamic Republic, where religion and politics were one.

His book, “Islamic Government,” was banned in Iran, so it spread underground.
The Shah thought the clerics were his allies.

After all, they hated communism. But that was his mistake.

By suppressing secular opposition and empowering the religious elite, he unknowingly handed them the infrastructure for revolution. Image
Khomeini was exiled in 1964. First to Iraq, then eventually to France.

But exile gave him power.

From a quiet suburb outside Paris, he recorded speeches, smuggled cassette tapes into Iran, and inspired a generation with his defiance. Image
In 1978, a revolution ignited.

• Mass protests erupted
• Strikes paralyzed the economy
• Demonstrators shouted: “Death to the Shah”

Each funeral turned into a rally. Each crackdown led to more martyrs.

The monarchy was unraveling by the day. Image
On January 16, 1979, the Shah fled Iran.

It was the end of a 2,500-year-old monarchy.

The "King of Kings" boarded a plane into exile.

And just 14 days later, Khomeini returned.

Millions flooded the streets to welcome him home. Image
This wasn’t just a regime change.

It was a total inversion of power:

• The exiled cleric triumphant
• The Westernized emperor gone
• The mosque replacing the palace
• The Quran replaces the constitution

Iran became the world’s first modern theocracy.
The shockwaves were global.

• U.S. officials were stunned
• Saudi Arabia grew nervous
• The Cold War dynamic shifted
• And Iran’s oil, once flowing freely to the West was now weaponized

Khomeini's rise reshaped geopolitics overnight.
But inside Iran, the revolution was complex.

Secular nationalists, communists, and liberals had all helped overthrow the Shah.

But Khomeini moved quickly.

He purged rivals, crushed dissent, and implemented Vilayat-e Faqih, a clerical rule.

His vision was non-negotiable.
In 1980, the Shah died in exile.

A cancer-stricken king, buried in Cairo.

In 1989, Khomeini died in Tehran.

Buried as a hero and surrounded by millions. Image
Image
The 1979 Iranian Revolution wasn’t just an uprising.

It was a turning point.

• It ended the Pahlavi dynasty
• It birthed a new kind of state
• And it challenged the West’s grip on West Asia

The world is still living with its consequences.

In 1982, "God’s Banker" was found hanging from a London bridge.

A $790M scandal, mafia ties & secret Vatican accounts, all leading to one question:

How did the Vatican build a financial empire so powerful yet shrouded in mystery?

Here’s the untold story of power & corruption: Image
Image
The Vatican wasn’t always a financial titan.

In the early 19th century, the church faced its gravest crisis.

After Napoleon invaded Rome in 1798, Pope Pius VI was taken captive, and the Papal States, a key source of income, were lost.

The Vatican was on the brink of collapse.
Enter the Rothschilds.

In 1831, Pope Gregory XVI made a controversial decision to secure the Vatican’s survival: borrowing money from the Rothschild banking dynasty.

This move shocked many within the church. Image

In the 1950s, the CIA drugged Americans with LSD without their knowledge.

They used hypnosis, torture, and electroshock to try to control their minds.

It was called MKUltra.

And this is the story of the most horrifying government experiment in US history: Image
After World War II, the CIA feared the Soviets had mind control technology.

They wanted a weapon to control human behavior, and in 1953, MKUltra was born.

The mission?

Turn science fiction into reality, no matter the cost.
Under MKUltra, the CIA tested LSD, hypnosis, electroshock therapy, sensory deprivation, and even biological agents.

But the most disturbing part?

These experiments were done on unwitting Americans without consent.

In 1860, a French explorer stumbled upon a lost empire buried in the Cambodian jungle.

Angkor Wat—larger than medieval London, built by god-kings, powered by advanced engineering.

Then it mysteriously vanished.

Here’s the untold story of its rise and fall: Image
Mouhot was astonished by the sheer scale of what he uncovered.

Angkor Wat, a 900-year-old religious complex, is the largest religious monument in the world.

Its intricately carved stone reliefs, vast corridors, and lotus-shaped towers rival the great cathedrals of Europe.
But this was only the beginning.

Radar imaging and modern archaeology have revealed that Angkor Wat was part of Angkor Thom, a metropolis as large as modern-day London.

For over 300 years, Barbary pirates enslaved 1 million Europeans & Americans.

They raided ships, burned villages, and sold captives like cattle.

Until 8 U.S. Marines took on a pirate empire and ended the white slave trade forever.

Here’s the untold story that changed history: Image
Between the 16th and 19th centuries, the Barbary corsairs operated from the North African coast, targeting ships from Europe and the Americas.

These pirates from Morocco, Algeria, Tunisia, and Libya loot cargo and enslave crews.
Coastal towns from Ireland to Iceland weren’t safe either.

The corsairs raided villages, kidnapping women, children, and the elderly to sell in bustling slave markets in Algiers and Tripoli.

In 1631, corsairs abducted nearly the entire population of Baltimore, Ireland.

2,500 years ago, Persia ruled the world.

At its heart stood Persepolis—a city so rich that the Greeks called it paradise on earth.

Then, in a single night, it was burned to the ground.

Here's how Persia built the greatest empire in history and how it was erased: Image
In 515 BC, Darius the Great ordered the construction of a new ceremonial capital, Persepolis.

Built on a grand terrace carved into a mountainside, the city was unlike anything the world had seen.

Every detail was designed to project Persian power.
- A 15-meter-high artificial platform overlooking the land

- Enormous palaces with 20-meter-tall cedar columns

- Gold-adorned gates guarded by colossal winged bulls

- Walls covered in dazzling textiles and jewel-studded thrones Image
