Abu Nasr Baha al-Din Sabur ibn Ardashir (Arabic: ابونصر بهاء الدين شاپور بن اردشیر; also spelled Shapur) was a Persian statesman who served as the vizier of the Buyids of Iraq five times between 990/1 to 1000.
[1] His first tenure was of brief duration, being arrested a year later, and escaping to the Batihah marshlands after his release,[2] where he possessed estates and some sort of power base, that often served as a refuge in his career.
[1] Sabur was re-appointed to the vizierate on 10 October 992, jointly with Ibn Salihan, until they both resigned their office following a mutiny of the Dailamite soldiery in 993/4.
[3] Their successor, Abu'l-Qasim Ali ibn Ahmad al-Abarquhi, did not last long in the office, fleeing in turn to Batihah, so that Sabur was appointed vizier again in the same year.
[1][5] He is best remembered for his patronage of scholars and poets, as well as the foundation of a college (dar al-ilm) in the Bayn al-Surayn quarter of Baghdad, with a library of 10,000 books.
