Known as Persia until 1935, Iran became an Islamic republic in 1979 after the ruling monarchy was overthrown and Shah Mohammad Reza PAHLAVI was forced into exile. Conservative clerical forces established a theocratic system of government with ultimate political authority vested in a learned religious scholar referred to commonly as the Supreme Leader who, according to the constitution, is accountable only to the Assembly of Experts. US-Iranian relations have been strained since a group of Iranian students seized the US Embassy in Tehran on 4 November 1979 and held it until 20 January 1981. During 1980-88, Iran fought a bloody, indecisive war with Iraq that eventually expanded into the Persian Gulf and led to clashes between US Navy and Iranian military forces between 1987 and 1988. Iran has been designated a state sponsor of terrorism for its activities in Lebanon and elsewhere in the world and remains subject to US, UN, and EU economic sanctions and export controls because of its continued involvement in terrorism and its nuclear weapons ambitions. Following the election of reformer Hojjat ol-Eslam Mohammad KHATAMI as president in 1997 and similarly a reformer Majles (parliament) in 2000, a campaign to foster political reform in response to popular dissatisfaction was initiated. The movement floundered as conservative politicians, through the control of unelected institutions, prevented reform measures from being enacted and increased repressive measures. Starting with nationwide municipal elections in 2003 and continuing through Majles elections in 2004, conservatives reestablished control over Iran's elected government institutions, which culminated with the August 2005 inauguration of hardliner Mahmud AHMADI-NEJAD as president.

Among the ideas imported into Iran from the West was the notion that women should participate in the public sphere. The Pahlavi government encouraged women to get as much education as possible and to participate in the labor force at all levels. After 1936, when Reza Shah banned the chador, veiling came to be perceived among the minority of elite and secular middle-class women as a symbol of oppression. Before the Revolution, Iranian society was already polarized between the traditionally minded majority and a minority of involved women who were dedicated to improving the status of women. As early as 1932, Iranian women held a meeting of the Oriental Feminine Congress in Tehran at which they called for the right of women to vote, compulsory education for both boys and girls, equal salaries for men and women, and an end to polygyny. In 1963 women were given the right to vote and to hold public office. Source: Iran: A Country Study
