Caliph is the term or title for the Islamic leader of the Ummah, or community of Islam. It is a romanized version of the Arabic word خليفة or Khalīfah () which means "successor" or "representative". Some of the early leaders of the Muslim community following the prophet Muhammad's (570–632) death called themselves "Khalifat Allah", meaning representative of God, but the alternative title of "Khalifat rasul Allah", meaning the successor to the prophet of God, eventually became the standard title. Some academics prefer to transliterate the term as Khalīf.
Caliphs were often also referred to as Amīr al-Mu'minīn (أمير المؤمنين) "Commander of the Faithful", or, more colloquially, leader of the Muslims. This title has been shortened and romanized to "emir". It is also found as a personal name in some countries (Amir or Aamir).
(Caliph, Khalīfah, also became the term used to designate the head of a Sufi order.)
After the first four Sunni caliphs (Abu Bakr, Umar ibn al-Khattab, Uthman ibn Affan, and Ali ibn Abi Talib), the title was claimed by the Umayyads, the Abbasids, and the Ottomans, as well as by other, competing lineages in Spain, Northern Africa, and Egypt. Most historical Muslim rulers simply titled themselves sultans or amirs, and gave token obedience to a caliph who often had very little real authority. The title has been defunct since the Republic of Turkey abolished the Ottoman caliphate in 1924.
Fred M. Donner, in his book The Early Islamic Conquests (1981), argues that the standard Arabian practice at the time was for the prominent men of a kinship group, or tribe, to gather after a leader's death and choose a leader from amongst themselves. There was no specified procedure for this shura, or consultation. Candidates were usually from the same lineage as the deceased leader, but they were not necessarily his sons. Capable men who would lead well were preferred over an ineffectual direct heir.
This is also the argument advanced by Sunni Muslims, who believe that Muhammad's lieutenant Abu Bakr was chosen by the community and that this was the proper procedure. They further argue that a caliph is ideally chosen by election or community consensus, even though the caliphate soon became a hereditary office, or the prize of the strongest general.
Shi'a Muslims disagree. They believe that Muhammad had given many indications that he considered , his cousin and son-in-law, as his chosen successor. They say that Abū Bakr seized power by force and trickery. All caliphs other than were usurpers. and his descendents are believed to have been the only proper Muslim leaders, or imams. This matter is covered in much greater detail in the article Succession to Muhammad, and in the article on Shi'a Islam.
A third branch of Islam, the Ibadi, believes that the caliphate rightly belongs to the greatest spiritual leader among Muslims, regardless of his lineage. They are currently an extremely small sect, found mainly in Oman.
Who should succeed Muhammad was not the only issue that faced the early Muslims; they also had to clarify the extent of the leader's powers. Muhammad, during his lifetime, was not only the Muslim leader, but the Muslim prophet and the Muslim judge. All law and spiritual practice proceeded from Muhammad. Was his successor to have the same status?
None of the early caliphs claimed to receive divine revelations, as did Muhammad; none of them claimed to be a nabī, "a prophet" or a "rasul" or divine messenger. Muhammad's revelations were soon codified and written down as the Qur'an, which was accepted as a supreme authority, limiting what a caliph could legitimately command.
However, there is some evidence that the early caliphs did believe that they had authority to rule in matters not specified in the Qur'an. They believed themselves to be the spiritual and temporal leaders of Islam, and insisted that implicit obedience to the caliph in all things was the hallmark of the good Muslim. The modern scholars Patricia Crone and Martin Hinds, in their book God's Caliph, outline the evidence for an early, expansive view of the caliph's importance and authority. They argue that this view of the caliphate was eventually nullified (in Sunni Islam, at least) by the rising power of the ulema, or Islamic scholars, clerics, and religious specialists. The ulema insisted on their right to determine what was legal and orthodox. The proper Muslim leader, in the ulema's opinion, was the leader who enforced the rulings of the ulema, rather than making rulings of his own. Conflict between caliph and ulema was a recurring theme in early Islamic history, and ended in the victory of the ulema. The caliph was henceforth limited to temporal rule. He would be considered a righteous caliph if he were guided by the ulema. Crone and Hinds argue that Shi'a Muslims, with their expansive view of the powers of the imamate, have preserved some of the beliefs of early Islam. Crone and Hinds' thesis is not accepted by all scholars.
Most Sunni Muslims now believe that the caliph has always been a merely temporal ruler, and that the ulema has always been responsible for adjudicating orthodoxy and Islamic law (shari'a). The first four caliphs are called the Rashidun, the Rightly Guided Caliphs, because they are believe to have followed the Qur'an and the way or sunnah of Muhammad in all things. This formulation itself presumes the Sunni ulema's view of history.
One of 's challengers was , a relative of Uthman. After 's death, managed to overcome all other claimants to the Caliphate. He is remembered by history as , the founder of the Umayyad dynasty. Under , the caliphate became a hereditary office.
However, the Umayyad dynasty was not universally supported within Islam itself. Some Muslims supported prominent early Muslims like az-Zubayr; others felt that only members of Muhammad's clan, the Banū Hashim, or his own lineage, the descendants of , should rule. There were numerous rebellions against the Umayyads, as well as splits within the Umayyad ranks (notably, the rivalry between Yaman and Qays). Eventually, supporters of the Banu Hisham and Alid claims united to bring down the Umayyads in 750. However, the , "the Party of ", were again disappointed when the Abbasid dynasty took power, as the Abbasids were descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib and not from . Following this disappointment, the finally split from the majority Sunni Muslims and formed what are today the several denominations.
During the period of the Abassid dynasty, Abassid claims to the caliphate did not go unchallenged. The Said ibn Husayn of the Fatimid dynasty, which claimed descendancy of Muhammad through his daughter, claimed the title of Caliph in 909, creating a separate line of caliphs in North Africa. Initially covering Morocco, Algeria, Tunisia and Libya, the Fatimid caliphs extended their rule for the next 150 years, taking Egypt and Palestine, before the Abbassid dynasty was able to turn the tide, limiting Fatimid rule to Egypt. The Fatimid dynasty finally ended in 1171. The Umayyad dynasty, which had survived and come to rule over the Muslim provinces of Spain, reclaimed the title of Caliph in 929, lasting until it was overthrown in 1031.
As the Ottoman Empire grew in size and strength, Ottoman rulers beginning with Mehmed II began to claim caliphal authority. Their claim was strengthened when the Ottoman Empire defeated the Mamluk Sultanate in 1517 and took control of most Arab lands. The last Abbasid Caliph at Cairo, al-Mutawakkil III, was taken prisoner and transported to Constantinople, where he reportedly surrendered the Caliphate to Selim I.
According to Barthold, the first time the title of caliph was used as a political instead of symbolic religious title by the Ottomans was the peace treaty with Russia in 1774. The outcome of this war was disastrous for the Ottomans. Large territories , including those with large muslim populations such as Crimea were lost to the christian Russian Empire. However, the Ottomans under Abdulhamid I claimed a diplomatic victory by assigning themselves the protectors of muslims in Russia as part of the peace treaty. This was the first time the Ottoman caliph was acknowledged as having political significance outside of Ottoman borders by a European power. As a consequence of this diplomatic victory, as the Ottoman borders were shrinking, the powers of the Ottoman caliph increased. Around 1880 Sultan Abdulhamid II reasserted the title as a way of countering creeping European colonialism in Muslim lands. His claim was most fervently accepted by the Muslims of British India. By the eve of the First World War, the Ottoman state, despite its weakness vis-a-vis Europe, represented the largest and most powerful independent Islamic political entity. But the sultan also enjoyed some authority beyond the borders of his shrinking empire as caliph of Muslims in Egypt, India and Central Asia.
Though Islam is still a dominant influence in most Muslim societies and many Muslims might favor a caliphate in the abstract, tight restrictions on political activity in many Muslim countries coupled with the tremendous practical obstacles to uniting over fifty disparate nation-states under a single institution have prevented efforts to revive the caliphate from garnering much active support, even amongst devout Muslims. Popular apolitical Islamic movements such as the Tablighi Jamaat identify a lack of spirituality and decline in religious observance as the root cause of the Muslim World's problems, and claim that the caliphate cannot be successfully revived until these deficiencies are addressed. No attempts at rebuilding a power structure based on Islam were successful anywhere in the Muslim World until the Iranian Revolution in 1979, which was based on Shia principles and did not deal with the issue of a global caliphate openly, but used covert actions to attempt to destablize other governments - before the US installed democratic government - and Somalia most succesfully and install Sharia, making it easier to unite the various muslim countries into a caliphate.
Various Sunni Islamist movements have gained momentum in recent years, calling for a restoration of the caliphate. However many such movements have as yet been unable to agree on a roadmap or a coherent model of Islamic governance, and dialog on this issue amongst Muslim activists and intellectuals has yielded no clear consensus on what a modern Islamic state should look like. Islamic religious scholars and institutions have struggled to define the applicability of centuries-old doctrines within the context of a modern society, and Islamic scholarship is generally thought to have failed to keep pace with scientific, technological, and social progress. Many questions on the form a modern Islamic caliphate would take, such as whether the concept of the caliphate is compatible with the modern nation-state construct, have received minimal attention in traditional Islamic scholarly circles. Mainstream Islamic institutions in Muslim countries today have generally not made the restoration of the caliphate a top priority and have instead focused on other issues.
One transnational group, the Hizb ut-Tahrir, has tried to recruit the world's Muslims to a renewed caliphate. They have published a draft constitution at *.
The more important dynasties include:
Note on the overlap of Umayyad and Abbasid Caliphates: After the massacre of the Umayyad clan by the Abbassids, one lone prince escaped and fled to North Africa, which remained loyal to the Umayyads. This was Abd-ar-rahman I. From there, he proceeded to Spain, where he overthrew and united the provinces conquered by previous Umayyad Caliphs (in 712 and 712). From 756 to 929, this Umayyad domain in Spain was an independent emirate, until Abd-ar-rahman III reclaimed the title of Caliph for his dynasty. The Umayyad Emirs of Spain are not listed in the summary below because they did not claim the caliphate until 929. For a full listing of all the Umayyad rulers in Spain see the Umayyad article.
Many local rulers throughout Islamic history have claimed to be caliphs. Most claims were ignored outside their limited domains. In many cases, these claims were made by rebels against established authorities and died when the rebellion was crushed. Notable claimants include:
