There was no one ruler of the Iranian Revolution but there were several major members of the revolution. The main was was the cleric Ayatollah Khomeni. He was preaching against the Shah throughout the whole revolution. The Shah actually exiled him from Iran but Khomeni still managed to preach against him because he sent tapes of his preaching back into Iran.

Iran is mostly Shiites who are deviated from the mainstream straight path of Islam; they visit the graves to perform some practice that invalidates the genuine creed of Islam such as asking the dead people to benefit them, help them or protect them etc. With regard to your question, it was the Khomeini who made the new regime on Iran in 1979.
