The 8th century is the period from 701 (DCCI) through 800 (DCCC) in accordance with the Julian Calendar. The coast of North Africa and the Iberian Peninsula quickly came under Islamic Arab domination. The westward expansion of the Umayyad Empire was famously halted at the siege of Constantinople by the Byzantine Empire and the Battle of Tours by the Franks. The tide of Arab conquest came to an end in the middle of the 8th century.
The 700s decade ran from January 1, 700, to December 31, 709.
Jaʿfar ibn Muḥammad al-Ṣādiq, commonly known as Ja'far al-Ṣādiq, was an 8th-century Muslim scholar. He was the 6th Imam and founder of the Ja'fari school of jurisprudence according to Twelver and Isma'ili Shi'ites. The traditions recorded from al-Sadiq are said to be more numerous than all hadiths recorded from all other Shia imams combined. He is also important to Sunnis as a teacher to the Sunni scholars Abu Hanifah and Malik ibn Anas and as a transmitter of Sunni hadith. Ja'far al-Sadiq also figures prominently in the initiatic chains of many Sufi orders. Despite the fact that a wide range of works in religious as well as scientific disciplines were attributed to him, no works penned by Ja'far himself remain extant.
Abu Muhammad Ismāʿīl ibn Jaʿfar al-Mubārak was the eldest son of Imam Ja'far al-Sadiq. He is also known as Isma'il Al-Ãraj ibn Ja'far. Following Ja'far's death, the Shia community split between those who believed the Imamate was passed to Musa ibn Ja'far, who would become the Twelver Shia, and those who believed that the Imamate passed to Isma'il ibn Ja'far, who would become the Isma'ili branch named after Isma'il.
Abu Muhammad Abdallah ibn al-Husayn, better known by his regnal name Al-Mahdi Billah, 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 faith.
This is a timeline of major events in the Muslim world from 701 AD to 800 AD.
The Musta‘lī are a branch of Isma'ilism named for their acceptance of al-Musta'li as the legitimate nineteenth Fatimid caliph and legitimate successor to his father, al-Mustansir Billah. In contrast, the Nizari—the other living branch of Ismailism, presently led by Aga Khan IV—believe the nineteenth caliph was al-Musta'li's elder brother, Nizar. Isma'ilism is a branch of Shia Islam.
