Thirty two legal and administrative documents from a private archive of a family from north-eastern Afghanistan, datable between AH 138 and AH 160 (AD 755-777). The history of Eastern Iran (Khurasan) in the Abbasid period has so far been based on literary sources, which, regrettably, tell us practically nothing of its administration, and the documentary material in Arabic has related almost entirely to papyri from Egypt. The lacuna has now, however, been dramatically filled by the discovery of the documents published in this volume, apparently from a private archive of landowners in north-eastern Afghanistan in the later 8th century AD. They appear to complement the more or less contemporary corpus of Bactrian documents in the Khalili Collection published by Nicholas Sims-Williams, which mention many of the persons and place-names in the Arabic documents. Together the two collections are of prime importance for the history of daily life in early Islamic Khurasan.
