The monarchy was overthrown in 1979 by the Iranian Revolution. In the same year a referendum was held by Ruhollah Khomeini, that asked whether there should be an 'Islamic Republic' or not. The 1979 referendum (in favor of an Islamic Republic) got 98% support of those who voted. The constitution was modeled on the 1958 constitution of the French Fifth Republic by the Assembly of Experts for Constitution (who were elected by direct popular vote) and Khomeini made himself the new Supreme Leader of Iran. The constitution received above 99% support in another 1979 referendum. After Khomeini's death, the Assembly of Experts (which is made of Islamic scholars elected by direct vote) appointed Ali Khamenei as the new Supreme Leader. The constitution was also amended through a referendum in 1989 with 97% support a few months before Ayatollah Ruhollah Khomeini died increasing the powers of Supreme Leader. Iran holds regular national elections by universal suffrage for all citizens (regardless of race, religion, or sex, who are of voting age) for electing the President, members of Parliament, Assembly of Experts, City and Village Councils where political parties support candidates.
