Iran country profile


Iran became an Islamic republic in 1979, when the monarchy was overthrown and clerics assumed political control under supreme leader Ayatollah Khomeini.

The Iranian revolution put an end to the rule of the Shah, who had alienated powerful religious, political and popular forces with a programme of modernisation and Westernisation, coupled with heavy repression of dissent.

Persia, as Iran was known before 1935, was one of the greatest empires of the ancient world, and the country has long maintained a distinct cultural identity within the Islamic world by retaining its own language and adhering to the Shia interpretation of Islam.

Supreme Leader: Ayatollah Ali Khamenei

The Supreme Leader - the highest power in the land - appoints the heads of the judiciary, military and media. He also confirms the election of the president.

Ayatollah Ali Khamenei was appointed for life in June 1989, succeeding Ayatollah Khomeini, the founder of the Islamic republic. He previously served two consecutive terms as president in the 1980s.

Iran has been led by a highly conservative clerical elite since the revolution in 1979.

Rouhani, who is regarded as a moderate, reformist figure, spearheaded the 2015 nuclear deal with world powers. He was elected in 2013.
