The Islamic Revolution destroyed the structures on which the shah's internal security policies depended. Mohammad Reza Shah had not tolerated dissent, had reacted strongly when challenged, and had relied on an elaborate internal security police force to enforce his absolute authority. Over the years, Khomeini had vigorously condemned the shah's secret police operations and continually called on Iranians to rise against a perceived tyrannical ruler. By the late 1970s, the shah's internal security organizations were in disgrace because of their abuses. In early 1979, the revolutionary regime dismantled existing security organizations and called on loyal citizens to protect the Revolution. Yet, like the shah, the revolutionary regime faced clear opposition to its authority.
