Your timeline is a little off. You should start with 1953 when the newly formed CIA and the brits overthrew the government there and installed our puppet and he created the secret police there.

In 1951, under Prime Minister
Mohammad Mosaddegh, the Iranian parliament voted to nationalize the British-owned oil industry, leading to the
Abadan Crisis. Despite British pressure, including an economic blockade, nationalization continued. Mosaddegh was removed from power in 1952 but was quickly re-appointed by the Shah, due to a popular uprising in support of the premier. He forced the Shah into a brief exile in August 1953 after a failed military coup by
Imperial Guard Colonel
Nematollah Nassiri.
On 19 August, a successful
coup was headed by retired army general
Fazlollah Zahedi, aided by the US (
CIA) and the British (
MI6), known as Operation Ajax and Operation Boot to the respective agencies.The coup—with a
black propaganda campaign against Mosaddegh—forced Mosaddegh from office. Mosaddegh was arrested and tried for treason. Found guilty, Mosaddegh had his sentence reduced to house arrest on his family estate while his foreign minister,
Hossein Fatemi, was executed.
Zahedi succeeded him as prime minister and suppressed opposition to the Shah, specifically from the
National Front and the communist
Tudeh Party.
From that time until the revolution, Iran was ruled as an autocracy under the Shah, with strong American support. Iran initiated economic, social, agrarian, and administrative reforms to modernize the country, which became known as the
White Revolution. Many Islamic leaders criticized these initiatives, and the land reform had mixed results. By 1978, the Shah had become wildly unpopular among the Iranian people. Daily demonstrations destabilized the region, and the Shah established
martial law to curb opposition. When hundreds of thousands of protestors persisted, security forces opened fire on the crowds in an incident that became known as
Black Friday
