Shia are a minority in Saudi Arabia, probably constituting about 5 percent of the total population, their number being estimated from a low of 200,000 to as many as 400,000. Shia are concentrated primarily in the Eastern Province, where they constituted perhaps 33 percent of the population, being concentrated in the oases of Qatif and Al Ahsa. Saudi Shia belong to the sect of the Twelvers, the same sect to which the Shia of Iran and Bahrain belong. The Twelvers believe that the leadership of the Muslim community rightfully belongs to the descendants of Ali, the son-in-law of the Prophet, through Ali's son Husayn (see Early Development of Islam , this ch.). There were twelve such rightful rulers, known as Imams, the last of whom, according to the Twelvers, did not die but went into hiding in the ninth century, to return in the fullness of time as the messiah (mahdi) to create the just and perfect Muslim society.

From a theological perspective, relations between the Shia and the Wahhabi Sunnis are inherently strained because the Wahhabis consider the rituals of the Shia to be the epitome of shirk (polytheism literally "association"), especially the Ashura mourning celebrations, the passion play reenacting Husayn's death at Karbala, and popular votive rituals carried out at shrines and graves. In the late 1920s, the Ikhwan (Abd al Aziz ibn Abd ar Rahman Al Saud's fighting force of converted Wahhabi beduin Muslims) were particularly hostile to the Shia and demanded that Abd al Aziz forcibly convert them. In response, Abd al Aziz sent Wahhabi missionaries to the Eastern Province, but he did not carry through with attempts at forced conversion. Government policy has been to allow Shia their own mosques and to exempt Shia from Hanbali inheritance practices. Nevertheless, Shia have been forbidden all but the most modest displays on their principal festivals, which are often occasions of sectarian strife in the gulf region, with its mixed Sunni-Shia populations.

Shia came to occupy the lowest rung of the socioeconomic ladder in the newly formed Saudi state. They were excluded from the upper levels of the civil bureaucracy and rarely recruited by the military or the police none was recruited by the national guard. The discovery of oil brought them employment, if not much of a share in the contracting and subcontracting wealth that the petroleum industry generated. Shia have formed the bulk of the skilled and semiskilled workers employed by Saudi Aramco. Members of the older generation of Shia were sufficiently content with their lot as Aramco employees not to participate in the labor disturbances of the 1950s and 1960s.

In 1979 Shia opposition to the royal family was encouraged by the example of Ayatollah Sayyid Ruhollah Musavi Khomeini's revolutionary ideology from Iran and by the Sunni Islamist (sometimes seen as fundamentalist) groups' attack on the Grand Mosque in Mecca in November. During the months that followed, conservative ulama and Ikhwan groups in the Eastern Province, as well as Shia, began to make theia88 eir criticisms of government heard. On November 28, 1979, as the Mecca incident continued, the Shia of Qatif and two other towns in the Eastern Province tried to observe Ashura publicly. When the national guard intervened, rioting ensued, resulting in a number of deaths. Two months later, another riot in Al Qatif by Shia was quelled by the national guard, but more deaths occurred. Among the criticisms expressed by Shia were the close ties of the Al Saud with and their dependency on the West, corruption, and deviance from the sharia. The criticisms were similar to those levied by Juhaiman al Utaiba in his pamphlets circulated the year before his seizure of the Grand Mosque. Some Shia were specifically concerned with the economic disparities between Sunnis and Shia, particularly since their population is concentrated in the Eastern Province, which is the source of the oil wealth controlled by the Sunni Al Saud of Najd. During the riots that occurred in the Eastern Province in 1979, demands were raised to halt oil supplies and to redistribute the oil wealth so that the Shia would receive a more equitable share.

After order was restored, there was a massive influx of government assistance to the region. Included were many large projects to upgrade the region's infrastructure. In the late 1970s, the Al Jubayl project, slated to become one of the region's largest employers, was headed by a Shia. In 1992, however, there were reports of repression of Shia political activity in the kingdom. An Amnesty International report published in 1990 stated that more than 700 political prisoners had been detained without charge or trial since 1983, and that most of the prisoners were Shia (see Prison Conditions , ch. 5).
