Aghlabid dynasty in the context of "Mu'tazilism"

Maltese (Maltese: Malti, also L-Ilsien Malti or Lingwa Maltija) is a Central Semitic language derived from late medieval Sicilian Arabic with Romance superstrata. It is the only Semitic language written in the Latin script. It is spoken by the Maltese people and is a national language of Malta, and is the only official Semitic and Afroasiatic language of the European Union. According to John L. Hayes, it descended from a North African dialect of Colloquial Arabic which was introduced to Malta when the Aghlabids captured it in 869/870 CE. It is also said to have descended from Siculo-Arabic, which developed as a Maghrebi Arabic dialect in the Emirate of Sicily between 831 and 1091. As a result of the Norman invasion of Malta and the subsequent re-Christianisation of the islands, Maltese evolved independently of Classical Arabic in a gradual process of Latinisation. It is therefore exceptional as a variety of historical Arabic that has no diglossic relationship with Classical or Modern Standard Arabic. Maltese is thus classified separately from the 30 varieties constituting the modern Arabic macrolanguage. Maltese is also distinguished from Arabic and other Semitic languages since its morphology has been deeply influenced by Romance languages, namely Italian and Sicilian.

The original Arabic base comprises around one-third of the Maltese vocabulary, especially words that denote basic ideas and the function words, but about half of the vocabulary is derived from standard Italian and Sicilian; and English words make up between 6% and 20% of the vocabulary. A 2016 study shows that, in terms of basic everyday language, speakers of Maltese are able to understand less than a third of what is said to them in Tunisian Arabic and Libyan Arabic, which are Maghrebi Arabic dialects related to Siculo-Arabic, whereas speakers of Tunisian Arabic and Libyan Arabic are able to understand about 40% of what is said to them in Maltese. This reported level of asymmetric intelligibility is considerably lower than the mutual intelligibility found between mainstream varieties of Arabic.

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.

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.

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.
