"Inspired by the success of the Cuban, Algerian, and Vietnamese revolutions and insurgencies, Iranian opposition groups of all political stripes, from Marxists to nationalists, religious fundamentalists to Islamist modernists, were exploring the option of an armed insurgency against the king of Iran. Shah Mohammad Reza Pahlavi had been on the throne since 1941, when his father, Reza Shah Pahlavi, had abdicated. The Persian empire was 2,500 years old, but the Pahlavi dynasty was young. In 1925, with help from the British, Reza Shah, a brigadier general in the Persian Cossack army, had put an end to two centuries of Qajar dynasty. Both father and son had faced challenges as they tried to force the rapid modernization of the country. In 1963, Shah Mohammad Reza Pahlavi had launched a wide program of reforms he described as a White Revolution. Khomeini and other clerics denounced what they saw as the Westernization of Iran by a despotic ruler. They were particularly incensed about the greater rights granted to women, including the right to run for elected office and serve as judges. Spurred by the clergy, leftists, antiroyalists, and student activists also took to the streets, each for their own reasons. The shah crushed the protests, killing dozens. Opposition leaders who were not arrested went underground or scattered abroad. Khomeini went to Turkey, then Iraq, but Lebanon provided convenient proximity for Iranian dissidents, along with religious and social affinities and even entertainment: the more secular revolutionaries could train during the day and go to the beach in the afternoon or spend their evenings in the bars of Beirut."
