"Much of the land once ruled by Nader Shah today forms the Islamic Republic of Iran, established in 1979 following the popular revolution that forced the abdication of the shah, Reza Pahlavi. His fall and exile saw the return of Ayatollah Ruhollah Khomeini, who oversaw the creation of a Shi'a-dominated theocracy that fused a populist socio-economic programme with fundamentalist Islamism. Virulent hatred of 'The Great Satan' America and the West (as demonstrated by the 1979-81 US embassy hostage crisis in Tehran and the death-penalty fatwa issued in 1989 against British author Salman Rushdie for his supposedly blasphemous work, The Satanic Verses), and anti-Zionism, provided the glue that held together the Republic. Whilst adhering to some democratic forms, Khomeini established a rigid theocratic leadership which ruthlessly stamped out opposition, establishing a vice-like grip over political activity that has never been relinquished. The Supreme Leader, an ayatollah, backed by the elite Revolutionary Guard and a vicious secret police, controls all policy and outranks the elected president and assembly."
