This book comprises English translations of Nizhādnāmah-i Afghān (Afghan Genealogy) and Taẕakkur al-Inqilāb (Memoir of the Revolution), the culminating works of Fayż Muḥammad Kātib Hazārah's monumental history of Afghanistan, Sirāj al-tawārīkh (The History of Afghanistan). Nizhādnāmah-i Afghān, a detailed guide to all the ethnic and religious communities in Afghanistan in the first third of the 20th century, is the first locally-produced ethnography by a modern Afghan scholar. The Taẕakkur al-Inqilāb is Fayz Muhammad's journalistic record of seven of the nine months of Amīr Ḥabīb Allāh Kalakānī's reign in 1929. Together with The History of Afghanistan these works offer an incomparable resource for the history of Afghanistan from the mid-18th to the mid-20th centuries.
