Jabir ibn Hayyan, known in the Latin West as Geber, is the name attached to the founding corpus of Arabic chemical writing, which shaped Islamic science and medieval alchemy. Tradition places him at the early Abbasid court; modern scholarship dates the corpus later and doubts a single author.

Malik-Shah I (1055-1092) was the third Seljuk sultan, under whom the empire reached its greatest extent and its administrative and cultural height. His reign produced the Jalali solar calendar, and it ended with the deaths of both his vizier Nizam al-Mulk and himself within weeks.

The Mihna (833–849 CE) was an inquisition begun by Caliph al-Ma'mun to enforce the Mu'tazilite doctrine that the Quran was created. Its failure, symbolized by Ahmad ibn Hanbal's resistance, established the independence of religious scholarship from political authority.
