Caliphate
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. 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, the Umayyad Caliphate, and the Abbasid Caliphate. 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, 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, however, believe a caliph should be an imam chosen by God from the Ahl al-Bayt. Some caliphates in history have been led by Shia Muslims, like the Fatimid Caliphate. 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 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 'king', or another from the same Semitic root. The term caliph derives from the Arabic word , meaning 'successor', 'steward', or 'deputy', and has traditionally been considered a shortening of '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 took place in the saqifa 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, 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 own allegiance to the latter, an example followed by the gathered men.

Abu Bakr was near-universally accepted as head of the Muslim community 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. Uthman was killed by members of a disaffected group. Ali then took control but was not universally accepted as caliph by the governors of Egypt and later by some of his own guard. He faced two major rebellions and was assassinated by Abd-al-Rahman ibn Muljam, a Khawarij. Ali's tumultuous rule 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 minority sect of Islam and reject the legitimacy of the first three caliphs. The followers of all four Rāshidun Caliphs became the majority Sunni sect.Under the Rāshidun, each region of the caliphate had its own governor. Muāwiyah, a relative of Uthman and governor 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, 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. The Persians, taking advantage of this, infiltrated the two armies and attacked the other army causing chaos and internal hatred between the companions at 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 elected as 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, named after the great-grandfather of Uthman and Mu'awiyah, Umayya ibn Abd Shams.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 into the Muslim world. At its greatest extent, the Umayyad Caliphate covered approximately 5 million square miles, 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. At the command of Yazid son of Muawiya, an army led by Umar ibn Saad, a commander by the name of Shimr Ibn Thil-Jawshan killed Ali's son Hussein 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 was constrained to hand over most of the royal functions to Muhammad ibn Ra'iq.
