Tus

Tus is an ancient city of Khurasan in northeastern Iran, near modern Mashhad. The Abbasid caliph Harun al-Rashid died there in 809, and the imam Ali al-Rida was buried in 818 beside him at nearby Sanabad; the shrine that grew around his tomb gave Mashhad its name. The poet Ferdowsi, born in a village near Tus, died and was buried there, and the theologian al-Ghazali was born in its district and died there in 1111. Other figures associated with the city include Nasir al-Din al-Tusi, Shaykh Tusi and Jabir ibn Hayyan. The Mongols sacked Tus in 1220.
