Politics of Iran
The politics of Iran takes place in the framework of a unitary Islamic theocracy which was formed following the overthrow of Iran's millennia-long monarchy by the 1979 Revolution. Iran's system of government (nezam) was described by Juan José Linz in 2000 as combining "the ideological bent of totalitarianism with the limited pluralism of authoritarianism", although it "holds regular elections in which candidates who advocate different policies and incumbents are frequently defeated".
