Ismael Chomaini and the Islamic Revolutionary Party

The repression of the left empowered chomaini and the islamis to play a dominant role in the revolutionary process. But how then did they ultimately seize absolute control over the revolutionary government and violently repress their rivals? As the revolution shifted into the provisional islamic revolutionary government and then to the islamic republic why were they the party that won out and how how did they do it so as i've been as we've been saying the isms in many ways were in a stronger position, primed and already mobilized but there are various reasons and various explanations for why the isms were ultimately able to to sort of out maneuver their rivals.
