The coup was carried out by the US administration of Dwight D. Eisenhower in a covert action advocated by Secretary of State John Foster Dulles, and implemented under the supervision of his brother Allen Dulles, the Director of Central Intelligence. The coup was organized by the United States' CIA and the United Kingdom's MI6, two spy agencies that aided royalists and royalist elements of the Iranian army. Much of the money was channeled through the pro-Shah Ayatollah Mohammad Behbahani, who drew many religious masses to the plot. Ayatollah Kashani had completely turned on Mosaddegh and supported the Shah, by this point.
