Episode Summary

With nationalization passed, Britain’s response came not at the negotiating table but on the water. Warships moved toward Abadan as London made clear it had no intention of accepting the law as final. Internally, the British pushed the Shah to appoint Sayyed Zia (a familiar face from the 1921 coup) as prime minister, hoping to steer Iran back toward compromise.

In the confirmation hearing, right-wing deputy, Jamal Emami, rose to mock Mosaddegh: “If Mosaddegh thought everyone else was failing, why not run the government himself?” The chamber fell silent. Then, Mosaddegh accepted. Seventy-nine deputies voted for him and afterwards the Majlis unanimously passed his follow-up nationalization legislation, establishing the National Iranian Oil Company and setting terms for auditing Anglo-Iranian’s books.

On May 1st, 1951, the Shah signed it into law.

Britain responded with an embargo. Anglo-Iranian’s general manager ordered tankers to leave Abadan empty rather than submit to Iranian oversight. The refinery ground to a halt.

America offered a mediator instead, Averell Harriman, carrying a letter from Truman himself. He spent ten days shuttling proposals between Tehran and the British. Every formula preserved some foreign role in managing Iranian oil. Mosaddegh rejected them all, warmly and completely.

When Iranian delegations moved into Anglo-Iranian’s offices, they found files being burned in a fireplace … but not quickly enough. What remained revealed decades of quiet interference: deputies bought, ministers managed, newspapers paid to undermine the National Front, a Radio Department official recruited as an asset. Mosaddegh released everything.

In Washington, Truman’s National Security Council heard the warnings plainly. The refinery was shutting down. British warships were already positioned off Abadan. Intelligence suggested an invasion was being considered. The Western alliance and Iran’s future hung in the balance.

The world was now deciding whether to let Iran’s nationalization stand … or crush it.

Episode Summary

In the early 1950s, Iran entered a period of rapid political upheaval. After disputed elections, a group of nationalists led by Mohammad Mosaddegh entered parliament, determined to challenge a revised oil agreement with the Anglo-Iranian Oil Company. Though framed as a financial improvement, the agreement left the core structure of foreign control intact. For Mosaddegh and his allies, the issue was not revenue, but sovereignty.

A parliamentary committee formed in 1950 turned the agreement into a national confrontation. While Prime Minister Ali Razmara sought compromise with Britain, proposing transparency and limited reforms, London refused to concede. The deadlock shifted momentum toward rejection, uniting unlikely factions across Iran’s political and religious spectrum.

Among them was Abolqasem Kashani, a cleric with deep anti-British convictions. His alignment with Mosaddegh signalled a broader transformation: oil was no longer just policy, but a national and moral cause.

Public opinion hardened further after news from Saudi Arabia, where a 50–50 oil profit-sharing agreement set a new benchmark. Iranian demands escalated beyond reform toward full control.

By early 1951, mass demonstrations filled the streets, calling for nationalization. Razmara warned of economic and political consequences, but his position collapsed as public anger intensified. On March 7, he was assassinated by a member of a militant religious group, removing the last advocate for compromise and deepening uncertainty around the balance of power.

With Razmara gone, momentum became irreversible. Under Mosaddegh’s leadership, the parliamentary oil committee voted unanimously to recommend nationalization. Days later, both the Majlis and Senate approved it without opposition. Iran’s oil industry was formally nationalized.

Across the country, celebrations followed. Diverse groups, clerics, nationalists, elites, and ordinary citizens, briefly united around a shared vision of independence. For a moment, Iran asserted control over its resources and its future.

But the decision also set the stage for confrontation. What began as a domestic dispute over oil had now become an international crisis.

Book One – Episode 8: Anglo-Persian Oil Company

Book Two – Episode 4: Anglo-Iranian Oil Company

Episode Summary

Abadan was not just a refinery. It was a world divided.

British managers lived behind garden walls and tennis courts. Iranian workers lived in Paper Cities, built from flattened oil drums, without water, without electricity, without shade.

In July 1946, they went on strike.

Fifty thousand workers walked off the job before dawn, and the refinery fell silent. For a day, it looked like organized defiance: crowds gathering, speeches about wages, dignity, legal rights. Then the atmosphere shifted. Street fighting broke out. The army moved in and declared martial law.

The strike was crushed. The structure remained untouched.

In the years that followed, the Anglo-Iranian Oil Company offered minor adjustments and symbolic gestures. Sir William Fraser, its chairman, saw the workers of Abadan as labour units, nothing more.

When formal talks produced a Supplemental Agreement in 1949, he declared the offer final, boarded his plane, and left.

Inside the Majlis, deputies were furious. The agreement left British control intact. But the Shah pushed for the passage of the supplemental agreement.

Stuck between their constitutions and the crown, Majlis stalled, filibustered, and let the parliamentary term expire without a vote.

But one figure was done with the delay.

Mohammad Mosaddegh had spent decades warning that foreign influence and royal overreach were two sides of the same problem. When the 1949 elections for the new Majlis were manipulated, he led a sit-in at the palace gates and forced a re-run in Tehran. He won. He organized. And the coalition he built (the National Front) transformed a dispute over royalty rates into something far harder to contain.

The oil question was no longer technical. It had become a question of sovereignty.
