Caliphs in the context of "List of Fatimid caliphs"

The Mamluk Sultanate (Arabic: سلطنة المماليك, romanized: Salṭanat al-Mamālīk), also known as Mamluk Egypt or the Mamluk Empire, was a state that ruled Egypt, the Levant and the Hejaz from the mid-13th to early 16th centuries, with Cairo as its capital. It was ruled by a military caste of mamluks (freed slave soldiers) headed by a sultan. The sultanate was established with the overthrow of the Ayyubid dynasty in Egypt in 1250 and was conquered by the Ottoman Empire in 1517. Mamluk history is generally divided into the Turkic or Bahri period (1250–1382) and the Circassian or Burji period (1382–1517), called after the predominant ethnicity or corps of the ruling Mamluks during these respective eras.

The first rulers of the sultanate hailed from the mamluk regiments of the Ayyubid sultan as-Salih Ayyub (r. 1240–1249), usurping power from his successor in 1250. The Mamluks under Sultan Qutuz and Baybars routed the Mongols in 1260, halting their southward expansion. They then conquered or gained suzerainty over the Ayyubids' Syrian principalities. Baybars also installed a surviving branch of the Abbasid dynasty in Cairo, who officially remained as caliphs and granted symbolic prestige to the sultanate. By the end of the 13th century, through the efforts of sultans Baybars, Qalawun (r. 1279–1290) and al-Ashraf Khalil (r. 1290–1293), the Mamluks had conquered the Crusader states, expanded into Makuria (Nubia), Cyrenaica, the Hejaz, and southern Anatolia. The sultanate then experienced a long period of stability and prosperity during the third reign of al-Nasir Muhammad (r. 1293–1294, 1299–1309, 1310–1341), before giving way to the internal strife characterizing the succession of his sons, when real power was held by senior emirs.

The Ottoman Caliphate (Ottoman Turkish: خلافت مقامى, romanized: hilâfet makamı, lit. 'office of the caliphate') was the claim of the heads of the Turkish Ottoman dynasty, rulers of the Ottoman Empire, to be the caliphs of Islam during the late medieval and early modern era.

Ottoman rulers first assumed the style of caliph in the 14th century, though did at that point not claim religious authority beyond their own borders. After the conquest of Mamluk Egypt by Sultan Selim I in 1517 and the abolition of the Mamluk-controlled Abbasid Caliphate, Selim and his successors ruled one of the strongest states in the world and gained control of Mecca, Medina and Jerusalem, the religious and cultural centers of Islam. The claim to be caliphs transitioned into a claim to universal caliphal authority, similar to that held by the Abbasid Caliphate prior to the sack of Baghdad in 1258. Further Ottoman victories, the dynasty's geopolitical dominance in the 16th–17th centuries, and the lack of rival claimants strengthened the Ottoman claim to be the leaders of the Muslim world.

The Rashidun (Arabic: الراشدون, romanized: al-Rāshidūn, lit. 'the rightly-guided') are the first four caliphs (lit. 'successors') who led the Muslim community following the death of Muhammad: Abu Bakr (r. 632–634), Umar (r. 634–644), Uthman (r. 644–656), and Ali (r. 656–661).

The reign of these caliphs, called the Rashidun Caliphate (632–661), is considered in Sunni Islam to have been 'rightly guided' (Arabic: rāshid), meaning that it constitutes a model (Sunnah) to be followed and emulated from a religious point of view.

Masjid al-Haram (Arabic: المسجد الحرام, romanized: al-Masjid al-Ḥarām, lit. 'The Sacred Mosque'), also known as the Sacred Mosque or the Great Mosque of Mecca, is considered to be the most significant mosque in Islam. It encloses the vicinity of the Kaaba in Mecca, in the western region of Saudi Arabia. It is among the pilgrimage sites associated with the Hajj, which every Muslim must perform at least once in their lives if able. It is also the main site for the performance of ʿUmrah, the lesser pilgrimage that can be undertaken any time of the year. The rites of both pilgrimages include circumambulating the Kaaba within the mosque. The Great Mosque contains other important sites, such as the Black Stone, the Zamzam Well, Maqam Ibrahim, and the hills of Safa and Marwa.

As of 2025, the Great Mosque is both the largest mosque in the world, and the most expensive building in the world. It has undergone major renovations and expansions through the years. It has passed through the control of various caliphs, sultans and kings, and is now under the control of the King of Saudi Arabia who is titled the Custodian of the Two Holy Mosques.

The Abbasid civil war of 865–866, sometimes known as the Fifth Fitna, was an armed conflict during the "Anarchy at Samarra" between the rival caliphs al-Musta'in and al-Mu'tazz, fought to determine who would gain control over the Abbasid Caliphate. The war, which lasted for about a year, largely revolved around a prolonged siege of Baghdad and ended with al-Mu'tazz as sole caliph. Al-Musta'in was abandoned by his supporters and forced to abdicate; in spite of a guarantee that his life would be spared, he was executed shortly afterward.

The outcome of the war was a major victory for the Turkic military establishment, which had been responsible for al-Mu'tazz's rise to power, and allowed the Turks to maintain their effective power over the government and military of the caliphate. The partisans of al-Musta'in, namely the Tahirid family, the Arab military factions, and the citizens of Baghdad, continued to be excluded from the politics of the central government after their surrender, although they were allowed to keep the positions they had before the war. Central Iraq, where most of the fighting took place, was devastated by the activities of both sides.

The succession to Muhammad in 632 led the Muslims to be split into two camps, the Sunnis, who believed that the caliphs of the Islamic community should be chosen by a council, as in Saqifa, while a second group, the Shia, who believed that Muhammad had named his successor to be Ali ibn Abi Talib, his cousin and son-in-law.

Today there are differences in religious practice and jurisprudence, traditions, and customs between Shia and Sunni Muslims. Although all Muslim groups consider the Quran to be divine, Sunni and Shia have different opinions on interpretations (hadith) of the Quran.
