Since the revolution in Iran, the largest Shia country, Twelver Shia political thought has been dominated by that of Ayatollah Ruhollah Khomeini, the founder and leader of the revolution. Khomeini that in the absence of the Hidden Imam and other divinely-appointed figures (in whom ultimate political authority rests), Muslims have not only the right, but also the obligation to establish an "Islamic state". To that end they must turn to scholars of Islamic law (fiqh) who are qualified to interpret the Quran and the writings of the imams.
