Al-Kamil fit-Tarikh (The Complete History)

الكامل في التاريخ

A comprehensive world history continuing where at-Tabari left off, covering events up to 1231 CE including the devastating Mongol invasions. Ibn al-Athir synthesized at-Tabari's multiple-narration approach into a single coherent narrative, making the history more accessible. The work is the primary source for the history of the Crusades from the Muslim perspective and the Mongol destruction of the Abbasid Caliphate.
