The 1979 Islamic Revolution in Iran is seen by some scholars as a success of Islamic fundamentalism. Some scholars argue that Saudi Arabia is also largely governed by fundamentalist principles (see Wahhabi movement) but Johannes J.G. Jansen disagrees, arguing that it is more akin to a traditional Muslim state, where a power separation exists between "princes" ("umarā") and "scholars" ("ulama"). In contrast, Jansen argues Khomeini came to power advocating a system of Islamic government where the highest authority is the hands of the "ulamā" (see "Wilayat al Faqih").
