Ifriqiya in the context of "Muhammad al-Qaim Bi-Amrillah"

The Arab Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Arab Muslim rule until conquered in turn by the Normans in the 11th century.

Although Sicily had been raided by the Muslim Arabs since the mid-7th century, these raids did not threaten Byzantine control over the island, which remained a largely peaceful backwater. The opportunity for the Aghlabid emirs of Ifriqiya (present-day Tunisia) came in 827, when the commander of the island's fleet, Euphemius, rose in revolt against the Byzantine Emperor Michael II. Defeated by loyalist forces and driven from the island, Euphemius sought the aid of the Aghlabids, an Arab dynasty. The latter regarded this as an opportunity for expansion and for diverting the energies of their own fractious military establishment and alleviating the criticism of the Islamic scholars by championing jihad, and dispatched an army to aid him. Following the Arab landing on the island, Euphemius was quickly sidelined. An initial assault on the island's capital, Syracuse, failed, but the Muslims were able to weather the subsequent Byzantine counter-attack and hold on to a few fortresses. With the aid of reinforcements from Ifriqiya and Umayyad al-Andalus, in 831 they took Palermo, which became the capital of the new Arab-Muslim province.

The Umayyad Caliphate or Umayyad Empire (US: /uːˈmaɪæd/; Arabic: ٱلْخِلَافَة ٱلْأُمَوِيَّة, romanized: al-Khilāfa al-Umawiyya) was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty from 661 to 750. It succeeded the Rashidun Caliphate, of which the third caliph, Uthman ibn Affan, was also a member of the clan. The Umayyad family established dynastic, hereditary rule with Mu'awiya ibn Abi Sufyan, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power was eventually claimed by Marwan ibn al-Hakam, from another branch of the clan. Syria remained the Umayyads' core power base thereafter, with Damascus as their capital.

The Umayyads continued the Muslim conquests, conquering Ifriqiya, Transoxiana, Sind, the Maghreb and Hispania (al-Andalus). At its greatest extent, the Umayyad Caliphate covered 11,100,000 km (4,300,000 sq mi), making it one of the largest empires in history in terms of area. The dynasty was toppled by the Abbasids in 750. Survivors of the dynasty established themselves in Córdoba which, in the form of an emirate and then a caliphate, became a world center of science, medicine, philosophy and invention during the Islamic Golden Age.

The Fatimid Caliphate (/ˈfætɪmɪd/; Arabic: الخلافة الفاطمیّة, romanized: al-Khilāfa al-Fāṭimiyya), also known as the Fatimid Empire, was a caliphate extant from the tenth to the twelfth centuries CE under the rule of the Fatimids, an Isma'ili Shi'a dynasty. Spanning a large area of North Africa and West Asia, it ranged from the western Mediterranean in the west to the Red Sea in the east. The Fatimids traced their ancestry to the Islamic prophet Muhammad's daughter Fatima and her husband Ali, the first Shi'a imam. The Fatimids were acknowledged as the rightful imams by different Isma'ili communities as well as by denominations in many other Muslim lands and adjacent regions. Originating during the Abbasid Caliphate, the Fatimids initially conquered Ifriqiya (roughly present-day Tunisia and north-eastern Algeria). They extended their rule across the Mediterranean coast and ultimately made Egypt the center of the caliphate. At its height, the caliphate included—in addition to Egypt—varying areas of the Maghreb, Sicily, the Levant, and the Hejaz.

Between 902 and 909, the foundation of the Fatimid state was realized under the leadership of da'i (missionary) Abu Abdallah, whose conquest of Aghlabid Ifriqiya with the help of Kutama forces paved the way for the establishment of the Caliphate. After the conquest, Abdallah al-Mahdi Billah was retrieved from Sijilmasa and then accepted as the Imam of the movement, becoming the first Caliph and founder of the dynasty in 909. In 921, the city of al-Mahdiyya was established as the capital. In 948, they shifted their capital to al-Mansuriyya, near Kairouan. In 969, during the reign of al-Mu'izz, they conquered Egypt, and in 973, the caliphate was moved to the newly founded Fatimid capital of Cairo. Egypt became the political, cultural, and religious centre of the empire and it developed a new and "indigenous Arabic culture". After its initial conquests, the caliphate often allowed a degree of religious tolerance towards non-Shi'a sects of Islam, as well as to Jews and Christians. However, its leaders made little headway in persuading the Egyptian population to adopt its religious beliefs.

Uthman ibn Affan (Arabic: عُثْمَان بْن عَفَّان, romanized: ʿUthmān ibn ʿAffān) (c. 573 or 576 – 17 June 656) was the third caliph of the Rashidun Caliphate, ruling from 644 until his assassination in 656. Uthman, a second cousin, son-in-law, and senior companion of the Islamic prophet Muhammad, played a major role in early Islamic history. During his reign as caliph, he was known for ordering the official compilation of the standardized version of the Quran, known as Uthman's Quran, that is still being used today.

Before his predecessor, caliph Umar (r. 634–644) died in office, he appointed a committee of trustees to elect a successor. Uthman, who was then aged 68–71 years, was elected to succeed him and became the oldest person to hold such a high position. During his premiership, the Caliphate expanded further into Persia and reached as far as the provinces of Khorasan and Transoxiana in the East as well as Ifriqiya and the Iberian Peninsula in the West. Uthman instituted centralized reforms in order to create a more cohesive administrative structure and fostered rapid economic growth.

The Berber Revolt or the Kharijite Revolt of 740–743 AD (122–125 AH in the Islamic calendar) took place during the reign of the Umayyad Caliph Hisham ibn Abd al-Malik and marked the first successful secession from the Arab caliphate (ruled from Damascus). Fired up by Kharijite puritan preachers, the Berber revolt against their Umayyad Arab rulers began in Tangier in 740, and was led initially by Maysara al-Matghari. The revolt soon spread through the rest of the Maghreb and across the straits to al-Andalus.

Although the Berbers managed to end Umayyad rule in the western Maghreb following the battles of Badgoura and of the Nobles, the Umayyads scrambled and managed to prevent the core of Ifriqiya (Tunisia, eastern Algeria and western Libya) and al-Andalus (Spain and Portugal) from falling into rebel hands, notably securing victory in the decisive battle of al-Asnam. However, the rest of the Maghreb was never brought back under Umayyad rule. After failing to capture the Umayyad provincial capital of Kairouan, the Berber rebel armies dissolved, and the western Maghreb fragmented into a series of small statelets, ruled by tribal chieftains and Kharijite imams.

The island of Sicily (Arabic: صِقِلِّيَة, romanized: Ṣiqilliya) was under Islamic rule from the late ninth to the late eleventh centuries. It became a prosperous and influential commercial power in the Mediterranean, with its capital of Palermo (بَلَرْم, Balarm) serving as a major cultural and political center of the Muslim world.

Sicily was a peripheral part of the Byzantine Empire when Muslim forces from Ifriqiya (roughly present-day Tunisia) began launching raids in 652. During the reign of the Aghlabid dynasty of Ifriqiya, a prolonged series of conflicts from 827 to 902 resulted in the gradual conquest of the entire island, with only the stronghold of Rometta, in the far northeast, holding out until 965. The Fatimid Caliphate replaced Aghlabid rule after 909. From 948 onwards, the island was governed by the Kalbid dynasty, who ruled as autonomous emirs while formally acknowledging Fatimid authority.

The Aghlabid dynasty (Arabic: الأغالبة) was an Arab dynasty centered in Ifriqiya (roughly present-day Tunisia) from 800 to 909 that conquered parts of Sicily, Southern Italy, and possibly Sardinia, nominally as vassals of the Abbasid Caliphate. The Aghlabids were from the tribe of Banu Tamim and adhered to the Mu'tazilite rationalist doctrine within Hanafi Sunni Islam, which they imposed as the state doctrine of Ifriqiya. They ruled until 909 when they were conquered by the new power of the Fatimids.

Roger II or Roger the Great (Italian: Ruggero II, Sicilian: Ruggeru II, Greek: Ρογέριος; 22 December 1095 – 26 February 1154) was King of Sicily and Africa, son of Roger I of Sicily and successor to his brother Simon. He began his rule as Count of Sicily in 1105, became Duke of Apulia and Calabria in 1127, then King of Sicily in 1130 and King of Africa in 1148.

Al-Walid ibn Abd al-Malik ibn Marwan (c. 674 – 23 February 715), commonly known as al-Walid I, was the sixth Umayyad caliph, ruling from October 705 until his death in 715. He was the eldest son of his predecessor, Caliph Abd al-Malik (r. 685–705). As a prince, he led annual raids against the Byzantines from 695 to 698 and built or restored fortifications along the Syrian Desert route to Mecca. He became heir apparent in c. 705, after the death of the designated successor, Abd al-Malik's brother Abd al-Aziz ibn Marwan.

Under al-Walid, his father's efforts to centralize government, impose a more Arabic and Islamic character on the state, and expand its borders were continued. He heavily depended on al-Hajjaj ibn Yusuf, his father's powerful viceroy over the eastern half of the caliphate. During his reign, armies commissioned by al-Hajjaj conquered Sind and Transoxiana in the east, while the troops of Musa ibn Nusayr, the governor of Ifriqiya, conquered the Maghreb and Hispania in the west, bringing the caliphate to its largest territorial extent. War spoils from the conquests enabled al-Walid to finance impressive public works, including his greatest architectural achievement, the Great Mosque of Damascus, as well as the al-Aqsa Mosque in Jerusalem, the expansions of the Prophet's Mosque in Medina and the Great Mosque of Sana'a, and the building of the historical city of Anjar. He was the first caliph to institute programs for social welfare, aiding the poor and handicapped among the Muslim Arabs of Syria, who held him in high esteem.

The Fatimid dynasty (Arabic: الفاطميون, romanized: al-Fāṭimiyyūn) was an Arab dynasty that ruled the Fatimid Caliphate, between 909 and 1171 CE. Descended from Fatima and Ali, and adhering to Isma'ili Shi'ism, they held the Isma'ili imamate, and were regarded as the rightful leaders of the Muslim community. The line of Nizari Isma'ili imams, represented today by the Aga Khans, claims descent from a branch of the Fatimids. The Alavi Bohras, predominantly based in Vadodara, also claim descent from the Fatimids.

The Fatimid dynasty emerged as the leaders of the clandestine early Isma'ili missionary movement (da'wa) in the ninth century CE, ostensibly acting on behalf of a hidden imam, implied at the time to be Muhammad ibn Isma'il. The Isma'ili da'wa spread widely across the Islamic world, then ruled by the Abbasid Caliphate. In 899, the future first Fatimid caliph, Abdallah, proclaimed himself to be the expected imam, causing a rift in the Isma'ili da'wa as the Qarmatians, who did not recognize his imamate, split off. In the meantime, Isma'ili agents had managed to conquer large parts of Yemen and Ifriqiya, as well as launch uprisings in Syria and Iraq. Fleeing Abbasid persecution to Ifriqiya, Abdallah proclaimed himself openly and established the Fatimid Caliphate in 909. From there, the Fatimid imam–caliphs extended their rule over most of the Maghreb as well as Sicily, before conquering Egypt in 969. Founding Cairo as their new capital, for the next two centuries, the Fatimids would be based in Egypt and identified with the country. At their height, the Fatimids claimed control or suzerainty over much of North Africa, Sicily, Egypt, the Levant, the Hejaz, Yemen, and Multan.

Abu Abdallah al-Husayn ibn Ahmad ibn Muhammad ibn Zakariyya, better known as Abu Abdallah al-Shi'i (Arabic: ابو عبد الله الشيعي, romanized: Abū ʿAbd Allāh ash-Shīʿī), was an Isma'ili missionary (dāʿī) active in Yemen and North Africa. He was successful in converting and unifying a large part of the Kutama Berber tribe, leading them on the conquest of Ifriqiya from 902 to 909 and the overthrowing of the Aghlabid dynasty. This ultimately led to the establishment of the Fatimid Caliphate in Ifriqiya under the Imam–caliph Abdullah al-Mahdi Billah. However, Abdullah al-Mahdi Billah quickly fell out with Abu Abdallah and had Abu Abdallah executed on 18 February 911.

The Kutama (Berber: Ikutamen; Arabic: كتامة) were a Berber tribe in northern Algeria classified among the Berber confederation of the Bavares. The Kutama are attested much earlier, in the form Koidamousii by the Greek geographer Ptolemy.

The Kutama played a pivotal role in establishing the Fatimid Caliphate (909–1171), forming the bulk of the Fatimid army which eventually overthrew the Aghlabids who controlled Ifriqiya, and which then went on to conquer Egypt, Sudan, Hijaz and the southern Levant in 969–975. The Kutama remained one of the mainstays of the Fatimid army until well into the 11th century.

Abū Muḥammad ʿAbd Allāh ibn al-Ḥusayn (Arabic: أبو محمد عبد الله بن الحسين; 31 July 874 – 4 March 934), better known by his regnal name al-Mahdī biʾllāh (Arabic: المهدي بالله, "The Rightly Guided by God"), was the founder of the Isma'ili Fatimid Caliphate, the only major Shi'a caliphate in Islamic history, and the eleventh Imam of the Isma'ili branch of Shi'ism.

He was born as Saʿīd ibn al-Ḥusayn (سعيد بن الحسين) in Askar Mukram to a family that led the secret Isma'ili missionary network (da'wa), propagating on behalf of the hidden imam, Muhammad ibn Isma'il, who would return as the prophesied Islamic messiah (mahdi). Orphaned at a young age, he moved to Salamiya, the family's base of operations, where he was adopted by his uncle. In the mid-890s Sa'id succeeded to the leadership of the expanding da'wa, which had expanded and gained adherents across the then Muslim world. However, his claims of not merely being a trustee of the hidden imam, but of him and his ancestors holding the imamate itself, led in 899 to a schism in the Isma'ili movement: those who did not recognise his claims split off to become the Qarmatians. The schism was followed by uprisings of pro-Isma'ili Bedouin in Syria in 902–903, launched without his consent by over-eager supporters, who aimed to force him to come forward as the mahdi. The Bedouin uprising was suppressed by the Abbasids, but drew the attention of the Abbasid Caliphate's authorities to him, forcing him to abandon Salamiya, and flee first to Ramla, then Fustat in Egypt, and finally Sijilmasa in what is now Morocco. There he remained, living as a merchant, until one of his missionaries, Abu Abdallah al-Shi'i, at the head of the Kutama Berbers overthrew the Aghlabid dynasty of Ifriqiya in 909.

Abu Tamim Ma'ad al-Mu'izz li-Din Allah (Arabic: أبو تميم معد المعزّ لدين الله, romanized: Abū Tamīm Maʿad al-Muʿizz li-Dīn Allāh, lit. 'Glorifier of the Religion of God'; 26 September 932 – 19 December 975) was the fourth Fatimid caliph and the 14th Ismaili imam, reigning from 953 to 975. It was during his caliphate that the center of power of the Fatimid dynasty was moved from Ifriqiya (modern Tunisia) to Egypt. The Fatimids founded the city of Cairo (al-Qāhirah, "the Victorious") in 969 as the new capital of the Fatimid Caliphate in Egypt during his reign. The Al-Mu'izz Street in Cairo is named after him, it is considrered to be the most important historical street in Cairo and it includes monumental buildings from the Fatimid era as well as the later Ayyubid, Memluk and Ottoman eras.

The Fatimid conquest of Egypt took place in 969 when the troops of the Fatimid Caliphate under the general Jawhar captured Egypt, then ruled by the autonomous Ikhshidid dynasty in the name of the Abbasid Caliphate.

The Fatimids launched repeated invasions of Egypt soon after coming to power in Ifriqiya (modern Tunisia and eastern Algeria) in 909, but failed against the still-strong Abbasid Caliphate. By the 960s, however, while the Fatimids had consolidated their rule and grown stronger, the Abbasid Caliphate had collapsed, and the Ikhshidid regime was facing prolonged crisis: foreign raids and a severe famine were compounded by the death in 968 of the strongman Abu al-Misk Kafur. The resulting power vacuum led to open infighting among the various factions in Fustat, the capital of Egypt. The atmosphere of crisis was deepened by the simultaneous advances of the Byzantine Empire against the Muslim states of the Eastern Mediterranean. Meanwhile, Fatimid agents operated openly in Egypt, and the local elites increasingly came to accept and even welcome the prospect of a Fatimid takeover in hopes of ending the instability and insecurity.

The Umayyad Caliphate or the Umayyad Empire (US: /uːˈmaɪæd/; Arabic: ٱلْخِلَافَة ٱلْأُمَوِيَّة, romanized: al-Khilāfa al-Umawiyya) was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty from 661 to 750. It succeeded the Rashidun Caliphate, of which the third caliph, Uthman ibn Affan, was also a member of the Umayyad clan. The Umayyad family established a dynasty with hereditary rule under Mu'awiya ibn Abi Sufyan, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power was eventually claimed by Marwan ibn al-Hakam, who came from another branch of the clan. Syria remained the Umayyads' core power base thereafter, with Damascus as their capital.

The Umayyads continued the Muslim conquests, conquering Ifriqiya, Transoxiana, Sind, the Maghreb and Hispania (al-Andalus). At its greatest extent, the Umayyad Caliphate covered an area of 11,100,000 km (4,300,000 sq mi), making it one of the largest empires in history in terms of size. The dynasty was overthrown by the Abbasids in 750. Survivors of the dynasty established an emirate and then a caliphate in Córdoba, with Cordoba becoming a major center of science, medicine, philosophy and invention during the Islamic Golden Age.
