Ethiopian historiography includes the ancient, medieval, early modern, and modern disciplines of recording the history of Ethiopia, including both native and foreign sources. The roots of Ethiopian historical writing can be traced back to the ancient Kingdom of Aksum (c. AD 100 – c. 940). These early texts were written in either the Ethiopian Ge'ez script or the Greek alphabet, and included a variety of mediums such as manuscripts and epigraphic inscriptions on monumental stelae and obelisks documenting contemporary events. The writing of history became an established genre in Ethiopian literature during the early Solomonic dynasty (1270–1974). In this period, written histories were usually in the form of royal biographies and dynastic chronicles, supplemented by hagiographic literature and universal histories in the form of annals. Christian mythology became a linchpin of medieval Ethiopian historiography due to works such as the Orthodox Kebra Nagast. This reinforced the genealogical traditions of Ethiopia's Solomonic dynasty rulers, which asserted that they were descendants of Solomon, the legendary King of Israel.

Ethiopian historiographic literature has been traditionally dominated by Christian theology and the chronology of the Bible. There was also considerable influence from Muslim, pagan and foreign elements from within the Horn of Africa and beyond. Diplomatic ties with Christendom were established in the Roman era under Ethiopia's first Christian king, Ezana of Axum, in the 4th century AD, and were renewed in the Late Middle Ages with embassies traveling to and from medieval Europe. Building on the legacy of ancient Greek and Roman historical writings about Ethiopia, medieval European chroniclers made attempts to describe Ethiopia, its people, and religious faith in connection to the mythical Prester John, who was viewed as a potential ally against Islamic powers. Ethiopian history and its peoples were also mentioned in works of medieval Islamic historiography and even Chinese encyclopedias, travel literature, and official histories.

The Taiping Yulan, translated as the Imperial Reader or Readings of the Taiping Era, is a massive Chinese leishu encyclopedia compiled by a team of scholars from 977 to 983. It was commissioned by the imperial court of the Song dynasty during the first era of the reign of Emperor Taizong. It is divided into 1,000 volumes and 55 sections, which consisted of about 4.7 million Chinese characters. It included citations from about 2,579 different kinds of documents spanning from books, poetry, odes, proverbs, steles to miscellaneous works. After its completion, the Emperor Taizong is said to have finished reading it within a year, going through 3 volumes per day. It is considered one of the Four Great Books of Song.

The team who compiled the Taiping Yulan includes: Tang Yue (湯悅), Zhang Wei (張洎), Xu Xuan (徐鉉), Song Bai (宋白), Xu Yongbin (徐用賓), Chen E (陳鄂), Wu Shu (吳淑), Shu Ya (舒雅), Lü Wenzhong (吕文仲), Ruan Sidao (阮思道), Hu Meng (扈蒙), Li Fang (李昉), and others.

The Huanglan or Imperial Mirror was one of the oldest Chinese encyclopedias or leishu "classified dictionary". Cao Pi, the first emperor of the Wei, ordered its compilation upon his accession to the throne in 220 and it was completed in 222. The purpose of the Huanglan was to provide the emperor and ministers of state with conveniently arranged summaries of all that was known at the time. Complete versions of the Huanglan existed until the Song dynasty (960-1279), when it became a mostly lost work, although some fragments did survive in other encyclopedias and anthologies. The Huanglan was the prototype of the classified encyclopedia and served as a model for later ones such as the (624) Tang Yiwen Leiju and the (1408) Ming Yongle dadian.
