Altan Debter

The Altan Debter (Persian: آلتان دبتر, from Mongolian Cyrillic: Алтан дэвтэр Altan devter, Mongolian script: ᠠᠯᠲᠠᠨ ᠳᠡᠪᠲᠡᠷAltan debter, the Golden Book) is an early, now lost history of the Mongols. Rashid-al-Din Hamadani had access to it when writing his Chronicles, Jami al-Tawarikh. Some believe that The Secret History of the Mongols is based on it, though the historian David Morgan argues that the two sources, though in agreement on broad facts and events, are "clearly quite independent of each other." It also inspired the still-extant Shengwu qinzheng lu.
