Yahya ibn Khalid

Yahya ibn Khalid (Arabic: يحيى بن خالد, yaḥyā bin ḫālid) (death 806) was a member of the powerful Persian Barmakids family, son of Khalid ibn Barmak.

Caliph al-Mahdi entrusted him in 778 with the education of his son Harun, who afterwards became Caliph as Harun al-Rashid, who made him Vizier.

He had three sons, among which Jafar succeeded him as Vizier, Musa ruled Damascus, and Fadl was governor of Khurasan, then of Egypt.

In 803 his family fell into disgrace, and he was cast into prison, where he died in 806 (according to the story, because his son Jafar had an affair with Harun al-Rashid's sister, most likely because the family had too much power).
