Beginning in 1963, Pahlavi implemented a number of reforms aimed at modernizing Iranian society, in what is known as the White Revolution. In light of his continued vocal opposition to the modernization campaign after being arrested twice, Khomeini was exiled from Iran in 1964. However, as major ideological tensions persisted between Pahlavi and Khomeini, anti-government demonstrations began in October 1977, eventually developing into a campaign of civil resistance that included elements of secularism and Islamism.
