Shiites (shēˈĪtz) [key] [Arab., shiat Ali, = the party of Ali], the second largest branch of Islam, Shiites currently account for 10%–15% of all Muslims. Shiite Islam originated as a political movement supporting Ali (cousin and son-in-law of Muhammad, the Prophet of Islam) as the rightful leader of the Islamic state. The legitimacy of this claim, as initially envisioned by Ali's supporters, was based on Muhammad's alleged designation of Ali as his successor, Ali's righteousness, and tribal customs, given his close relation to the Prophet. Ali's right passed with his death in 661 to his son Hasan, who chose not to claim it, and after Hasan's death, to Husein, Ali's younger son. The evolution into a religious formulation is believed to have been initiated with the martyrdom of Husein in 680 at Karbala (today in Iraq), a traumatic event still observed with fervor in today's Shiite world on the 10th of the month of Muharram of the Muslim lunar year.
The Shiite focus on the person of the Imam made the community susceptible to division on the issue of succession. The early Shiites, a recognized, if often persecuted, opposition to the central government, soon divided into several factions. The majority of the Shiites today are Twelve-Imam Shiites (notably in Iran, Iraq, Lebanon, Saudi Arabia, Bahrain, India, and Pakistan). Others are Zaydis (in Yemen), and the Ismailis (in India, Pakistan, Syria, and Yemen). The central belief of Twelve-Imam Shiites is the occultation (or disappearance from view) of the 12th Imam. The 12th Imam is considered to be the only legitimate and just ruler, and therefore no political action taken in his absence can be fruitful. While this position has provided Shiite clerics with the means to survive an often hostile environment, the need for an alternative formulation capable of framing political militancy has fostered activist movements within the Shiite tradition, occasionally leading to dissidence (see Babism).
The religious authority of the Shiite clerics is derived from their role as deputies of the absent 12th Imam; they are as such the recipients of the khums religious tax, a source of substantial economic autonomy. Shiite clerics are often refered to as mullahs and mujtahids. The most prominent clerical position is that of marja al-taqlid. The Shiite clergy does not, however, have a formal hierarchy. The honorific ayat Allah or ayatollah [Arab., = sign of God] is a modern title that does not correspond to any established religious function.
In Iran, the Safavid adoption of a Shiite state religion led to the expansion of clerical involvement in public life, under the tutelage of the political elite. The threat of European colonialism in the 19th cent. presented the opportunity for Shiite activist thought to gain impetus. The attempt of the Pahlevi monarchy in the 20th cent. to curtail the influence of the clerics further strengthened clerical political militancy. Benefiting from a ubiquitous clerical network, and enjoying a credibility unblemished by the corruption within the autocratic regime, Ruhollah Khomeini served as the culmination of the reintegration of activism into the Shiite mainstream. With the Iranian revolution in 1979, the Shiite activist formulation progressed toward stressing the nonsectarian pan-Islamic character of its ideology. Islam, it suggests, should be lived as a tool for the empowerment of the oppressed, not merely as a set of devotional practices; hence the Iranian support for the Palestinian, Afghan, and Lebanese causes.
