Yahya ibn Khalid
Yahya ibn Khalid was a member of the powerful Iranian-Assyrian Barmakids family, son of Khalid ibn Barmak. Around 765, he was appointed to Adharbayjan by the Caliph al-Mansur. Yahya's son Fadl ibn Yahya was born at Rayy, at the same time as Caliph al-Mahdi's son Harun. Al-Mahdi entrusted Yahya in 778 with Harun's education.
When al-Hadi was Caliph, Yahya dissuaded the Caliph several times from proclaiming his own son as heir instead of Harun. He eventually did so, and cast Yahya into jail, but died shortly after. When Harun became Caliph as Harun al-Rashid, he made Yahya vizier. Under his influence, the Caliph invited to Baghdad many scholars and masters from India, especially Buddhists. A catalogue of both Muslim and non-Muslim texts prepared at this time, Kitab al-Fihrist, included a list of Buddhist works. Among them was an Arabic version of the account of Buddha’s previous lives, Kitab al-Budd.
He had three sons, among which Ja'far 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.
