Introduction

Al-Kamil fit-Tarikh (The Complete History) is a twelve-volume universal chronicle compiled by the eminent Mosuli historian and litterateur Izz al-Din Ibn al-Athir — full name Ali ibn Muhammad ibn Muhammad al-Jazari al-Shaybani (555–630 AH / 1160–1233 CE). Born in Jazira ibn Umar in what is now southeastern Turkey, Ibn al-Athir came from a distinguished scholarly family; his elder brother was the celebrated literary critic and anthologist Majd al-Din, and another brother, Diya' al-Din, was a leading figure in Arabic rhetoric. Izz al-Din himself served the Zengid rulers of Mosul and later travelled widely, meeting Saladin and observing firsthand the turbulent events of the Crusader wars and the Mongol advance.

The work spans from the creation of the world to the year 628 AH (1231 CE), providing a year-by-year account of the major events of Islamic history. Ibn al-Athir explicitly positioned Al-Kamil as a synthesis and improvement on al-Tabari's Tarikh — incorporating al-Tabari's material while extending the coverage by three centuries, adding information from regional and dynastic chronicles unavailable to al-Tabari, and presenting the narrative in a more fluent, connected style. Where al-Tabari reproduced competing isnads in full, Ibn al-Athir typically selects the most reliable account and presents it directly, making the text more accessible to general readers while sacrificing some of the source-critical granularity of the earlier work.

As a historian who lived through the Third Crusade, the fall of Jerusalem to Saladin in 583 AH, and the opening phase of the Mongol invasions, Ibn al-Athir's eyewitness and near-contemporary sections carry exceptional value. His account of the Crusader states, the Zengid and Ayyubid dynasties, and the early Mongol campaigns under Genghis Khan and his commanders is considered among the most important contemporary Arabic sources for these events. He describes the Mongol devastation of Transoxiana and Khurasan in terms of profound grief, calling it a catastrophe unparalleled since the creation of man.

Ibn al-Athir's methodology combined the annalistic year-by-year format inherited from al-Tabari with a concern for narrative coherence and geographical breadth. He drew on sources from across the Islamic world — Iraqi, Syrian, Egyptian, and Persian chronicles — and made a deliberate effort to include the histories of regions and dynasties that earlier Baghdad-centred historians had treated marginally. His coverage of the Fatimid caliphate, the Seljuk empire, the Spanish Umayyads, and the various Turkish principalities reflects this wider scope.

Al-Kamil fit-Tarikh became one of the most copied and consulted historical works in the Islamic world. Ibn Khaldun, al-Maqrizi, and generations of Ottoman and Safavid historians drew on it extensively. The standard modern edition (Dar al-Kitab al-Arabi, Beirut) runs to thirteen volumes. Readers using Islam.wiki will find chapters organised by year (AH), with each section covering the major political, military, and scholarly events of that year alongside brief obituaries of notable scholars who died in it — a format that makes the work an invaluable reference for dating events and locating individuals within the flow of Islamic history.
