A caliphate is an institution or public office under the leadership of an Islamic steward with the title of caliph, a person considered a political–religious successor to the Islamic prophet Muhammad and a leader of the entire Muslim world (ummah). Historically, the caliphates were polities based on Islam which developed into multi-ethnic trans-national empires.
During the medieval period, three major caliphates succeeded each other: the Rashidun Caliphate (632–661), the Umayyad Caliphate (661–750), and the Abbasid Caliphate (750–1517). In the fourth major caliphate, the Ottoman Caliphate, the rulers of the Ottoman Empire claimed caliphal authority from 1517 until the Ottoman Caliphate was formally abolished as part of the 1924 secularisation of Turkey. The Sharif of Mecca then claimed the title, but this caliphate fell quickly after its conquest by the Sultanate of Nejd (the predecessor of modern-day Saudi Arabia), leaving the claim in dormancy. Throughout the history of Islam, a few other Muslim states, almost all of which were hereditary monarchies, have claimed to be caliphates.
Not all Muslim states have had caliphates. The Sunni branch of Islam stipulates that, as a head of state, a caliph should be elected by Muslims or their representatives. Shia Muslims believe a caliph should be an imam chosen by God from the Ahl al-Bayt (the 'Household of the Prophet'). Some caliphates in history have been led by Shia Muslims, like the Fatimid Caliphate (909–1171). From the late 20th century towards the early 21st century, in the wake of the invasion of Afghanistan by the USSR, the war on terror and the Arab Spring, various Islamist groups have claimed the caliphate, although these claims have usually been widely rejected among Muslims; the most notable example of this being the Islamic State led by Abu Bakr al-Baghdadi which declared a caliphate in its territory in Iraq and Syria in 2014.
Etymology
Before the advent of Islam, Arabian monarchs traditionally used the title malik 'king', or another from the same Semitic root. The term caliph () derives from the Arabic word khalīfah (خليفة, pronunciationⓘ), meaning 'successor', 'steward', or 'deputy', and has traditionally been considered a shortening of Khalīfah rasūl Allāh 'successor of the messenger of God'. However, studies of pre-Islamic texts suggest that the original meaning of the phrase was 'successor selected by God'.
History
Rashidun Caliphate (632–661)
Succession to Muhammad
In the immediate aftermath of the death of Muhammad, a gathering of the Ansar (natives of Medina) took place in the saqifa (courtyard) of the Banu Sa'ida clan. The meeting was thought to have convened so the Ansar could decide on a new leader of the Muslim community among themselves, with the intentional exclusion of the Muhajirun (migrants from Mecca), though this later became the subject of debate.
Nevertheless, Abu Bakr and Umar, both prominent companions of Muhammad, upon learning of the meeting became concerned of a potential coup and hastened to the gathering. Upon arriving, Abu Bakr addressed the assembled men with a warning that an attempt to elect a leader outside of Muhammad's own tribe, the Quraysh, would likely result in dissension as only they can command the necessary respect among the community. He then took Umar and another companion, Abu Ubayda ibn al-Jarrah, by the hand and offered them to the Ansar as potential choices. He was countered with the suggestion that the Quraysh and the Ansar choose a leader each from among themselves, who would then rule jointly. The group grew heated upon hearing this proposal and began to argue among themselves. Umar hastily took Abu Bakr's hand and swore his allegiance to the latter, an example followed by the gathered men.
Abu Bakr was near-universally accepted as head of the Muslim community (under the title of caliph) as a result of Saqifah, though he did face contention as a result of the rushed nature of the event. Several companions, most prominent among them being Ali ibn Abi Talib, initially refused to acknowledge his authority. Ali may have been reasonably expected to assume leadership, being both cousin and son-in-law to Muhammad. The theologian Ibrahim al-Nakha'i stated that Ali also had support among the Ansar for his succession, explained by the genealogical links he shared with them. Whether his candidacy for the succession was raised during Saqifah is unknown, though it is not unlikely. Abu Bakr later sent Umar to confront Ali to gain his allegiance, resulting in an altercation which may have involved violence. However, after six months, the group made peace with Abu Bakr and Ali offered him his fealty.
Rashidun caliphs
Abu Bakr nominated Umar as his successor on his deathbed. Umar, the second caliph, was killed by a Persian slave called Abu Lu'lu'a Firuz. His successor, Uthman, was elected by a council of electors (majlis). Uthman was killed by members of a disaffected group. Ali then took control but was not universally accepted as caliph. He faced two major rebellions and was assassinated following a tumultuous rule that lasted only five years. This period is known as the Fitna, or the first Islamic civil war. The followers of Ali later became the Shi'a ("shiaat Ali", partisans of Ali.) minority sect of Islam and reject the legitimacy of the first three caliphs. Those who accepted all four Rāshidun Caliphs (Abu Bakr, Umar, Uthman and Ali) became the majority Sunni sect.
Under the Rāshidun, each region (Sultanate, Wilayah, or Emirate) of the caliphate had its own governor (Sultan, Wāli or Emir). Muāwiyah, a relative of Uthman and governor (wali) of Syria, succeeded Ali as caliph. Muāwiyah transformed the caliphate into a hereditary office, thus founding the Umayyad dynasty.
In areas which were previously under Sasanian Empire or Byzantine rule, the caliphs lowered taxes, provided greater local autonomy (to their delegated governors), greater religious freedom for Jews and some indigenous Christians, and brought peace to peoples demoralised and disaffected by the casualties and heavy taxation that had resulted from the decades of Byzantine–Persian warfare.
Ali's caliphate, Hasan and the rise of the Umayyads
Ali's reign was plagued by turmoil and internal strife, culminating in the Battle of Siffin. The battle lasted several months, resulting in a stalemate. To avoid further bloodshed, Ali agreed to negotiate with Mu'awiyah. This caused a faction of approximately 4,000 people, who would come to be known as the Kharijites, to abandon the fight. After defeating the Kharijites at the Battle of Nahrawan, Ali was later assassinated by the Kharijite Ibn Muljam. Ali's son Hasan was proclaimed the next caliph, but abdicated in favour of Mu'awiyah a few months later to avoid any conflict within the Muslims. Mu'awiyah became the sixth caliph, establishing the Umayyad dynasty.
Umayyad Caliphate (661–750)
Beginning with the Umayyads, the title of the caliph became hereditary. Under the Umayyads, the caliphate grew rapidly in territory, incorporating the Caucasus, Transoxiana, Sindh, the Maghreb and most of the Iberian Peninsula (Al-Andalus) into the Muslim world. At its greatest extent, the Umayyad Caliphate covered approximately 5 million square miles (approximately 13 million square kilometres), making it larger than the earlier Roman Empire or contemporary Tang China.
Geographically, the empire was divided into several provinces, the borders of which changed a number of times during the Umayyad reign. Each province had a governor appointed by the caliph. However, for a variety of reasons, including that they were not elected by Shura and suggestions of impious behaviour, the Umayyad dynasty was not universally supported within the Muslim community. Some supported prominent early Muslims like Zubayr ibn al-Awwam; others felt that only members of Muhammad's clan, the Banu Hashim, or his own lineage, the descendants of Ali, should rule.
There were multiple rebellions against the Umayyads, as well as splits within the Umayyad ranks (notably, the Qays–Yaman rivalry). At the command of Yazid I, an army led by Umar ibn Sa'd and Shimr ibn Dhi 'l-Jawshan killed Ali's son Husayn ibn Ali and his family at the Battle of Karbala in 680, solidifying the Shia-Sunni split. Eventually, supporters of the Banu Hashim and the supporters of the lineage of Ali united to bring down the Umayyads in 750. However, the Shi‘at ‘Alī, "the Party of Ali", 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 Ali.
Abbasid Caliphate (750–1517)
Abbasid caliphs at Baghdad
In 750, the Umayyad dynasty was overthrown by another family of Meccan origin, the Abbasids. Their time represented a scientific, cultural and religious flowering. Islamic art and music also flourished significantly during their reign. Their major city and capital Baghdad began to flourish as a center of knowledge, culture and trade. This period of cultural fruition ended in 1258 with the sack of Baghdad by the Mongols under Hulagu Khan. The Abbasid Caliphate had, however, lost its effective power outside Iraq already by c. 920. By 945, the loss of power became official when the Buyids conquered Baghdad and all of Iraq. The empire fell apart and its parts were ruled for the next century by local dynasties.
In the ninth century, the Abbasids created an army loyal only to their caliphate, composed predominantly of Turkic Cuman, Circassian and Georgian slave origin known as Mamluks. By 1250 the Mamluks came to power in Egypt. The Mamluk army, though often viewed negatively, both helped and hurt the caliphate. Early on, it provided the government with a stable force to address domestic and foreign problems. However, creation of this foreign army and al-Mu'tasim's transfer of the capital from Baghdad to Samarra created a division between the caliphate and the peoples they claimed to rule. In addition, the power of the Mamluks steadily grew until Ar-Radi (934–941) was constrained to hand over most of the royal functions to Muhammad ibn Ra'iq.
Under the Mamluk Sultanate of Cairo (1261–1517)
In 1261, following the Mongol conquest of Baghdad, the Mamluk rulers of Egypt tried to gain legitimacy for their rule by declaring the re-establishment of the Abbasid Caliphate in Cairo. The Abbasid caliphs in Egypt had no political power; they continued to maintain the symbols of authority, but their sway was confined to religious matters. The first Abbasid caliph of Cairo was Al-Mustansir (r. June–November 1261). The Abbasid Caliphate of Cairo lasted until the time of Al-Mutawakkil III, who ruled as caliph from 1508 to 1516, then he was deposed briefly in 1516 by his predecessor Al-Mustamsik, but was restored again to the caliphate in 1517.
The Ottoman sultan Selim I defeated the Mamluk Sultanate and made Egypt part of the Ottoman Empire in 1517. Al-Mutawakkil III was captured together with his family and transported to Constantinople as a prisoner where he had a ceremonial role. He died in 1543, following his return to Cairo.
Parallel regional caliphates in the later Abbasid era
The Abbasid dynasty lost effective power over much of the Muslim realm by the first half of the tenth century.
The Umayyad dynasty, which had survived and come to rule over Al-Andalus, reclaimed the title of caliph in 929, lasting until it was overthrown in 1031.
During the Umayyad dynasty, the Iberian Peninsula was an integral province of the Umayyad Caliphate ruling from Damascus. The Umayyads lost the position of caliph in Damascus in 750, and Abd al-Rahman I became Emir of Córdoba in 756 after six years in exile. Intent on regaining power, he defeated the existing Islamic rulers of the area who defied Umayyad rule and united various local fiefdoms into an emirate.
Rulers of the emirate used the title "emir" or "sultan" until the tenth century, when Abd al-Rahman III was faced with the threat of invasion by the Fatimid Caliphate. To aid his fight against the invading Fatimids, who claimed the caliphate in opposition to the generally recognised Abbasid caliph of Baghdad, Al-Mu'tadid, Abd al-Rahman III claimed the title of caliph himself. This helped Abd al-Rahman III gain prestige with his subjects, and the title was retained after the Fatimids were repulsed. The rule of the caliphate is considered as the heyday of Muslim presence in the Iberian Peninsula, before it fragmented into various taifas in the eleventh century. This period was characterised by a flourishing in technology, trade and culture; a number of the buildings of al-Andalus were constructed in this period.
The Almohad Caliphate (Berber languages: Imweḥḥden, from الموحدون al-Muwaḥḥidun, "the Monotheists" or "the Unifiers") was a Moroccan Berber Muslim movement founded in the 12th century.
The Almohad movement was started by Ibn Tumart among the Masmuda tribes of southern Morocco. The Almohads first established a Berber state in Tinmel in the Atlas Mountains in roughly 1120. The Almohads succeeded in overthrowing the Almoravid dynasty in governing Morocco by 1147, when Abd al-Mu'min (r. 1130–1163) conquered Marrakech and declared himself caliph. They then extended their power over all of the Maghreb by 1159. Al-Andalus followed the fate of Africa, and all Islamic Iberia was under Almohad rule by 1172.
The Almohad dominance of Iberia continued until 1212, when Muhammad al-Nasir (1199–1214) was defeated at the Battle of Las Navas de Tolosa in the Sierra Morena by an alliance of the Christian princes of Castile, Aragon, Navarre and Portugal. Nearly all of the Moorish dominions in Iberia were lost soon after, with the great Moorish cities of Córdoba and Seville falling to the Christians in 1236 and 1248, respectively.
