Caliphate

The third major Islamic caliphate (750–1258 CE), centered in Baghdad. It presided over the Islamic Golden Age, with landmark advances in science, philosophy, literature, and the arts, forging a cosmopolitan empire that blended Greek, Persian, Indian, and Arab traditions.

A major Shia Islamic caliphate (909-1171 CE) that ruled North Africa, Egypt, and parts of the Middle East. Founded by the Ismaili Shia dynasty claiming descent from Fatimah, the Fatimids established a powerful empire centered in Cairo rivaling the Abbasid and Umayyad caliphates.

The first four Caliphs of Islam (632-661 CE), known as the 'Rightly-Guided Caliphs,' who succeeded Prophet Muhammad and established the foundations of Islamic civilization through unprecedented territorial expansion, administrative innovation, and preservation of Islamic teachings.

The division between Sunni and Shia Islam, originating from disputes over leadership succession after Prophet Muhammad's death, evolved into distinct theological, legal, and political traditions that have shaped Islamic civilization.

The Umayyad Caliphate (661-750 CE) was the first major Islamic dynasty, ruling from Damascus and expanding the Islamic empire from Spain to Central Asia through unprecedented territorial growth and administrative innovation.

The Umayyad and Abbasid Caliphates represented contrasting approaches to governance, culture, and Islamic identity. While the Umayyads built a vast Arab empire, the Abbasids created a cosmopolitan Islamic civilization.

The Umayyads of Cordoba ruled Al-Andalus from 756 to 1031 CE, turning a distant province into one of medieval Europe's most sophisticated states. Founded by Abd al-Rahman I, survivor of the Abbasid massacre of his family, the dynasty produced the Caliphate of Cordoba before civil war.
