The Enmannsche Kaisergeschichte ('Enmann's History of the Emperors') is a modern term for a hypothetical Latin historical work, written in the 4th century, but now lost.
In 1884, German scholar Alexander Enmann made a comparison of several late Roman historical works and found many similarities, which could not be explained by a direct literary relationship between the extant works (Eine verlorene Geschichte der roemischen Kaiser und das Buch De viris illustribus urbis Romae).
[2] Although the majority of scholars agreed with Enmann's hypothesis,[3] some, especially Willem den Boer [de], questioned the existence of the Kaisergeschichte.
In 2023, historians Justin A. Stover and George Woudhuysen argued that there was a stronger explanation for the similarities in several Roman historical works from the late fourth and fifth centuries.
Stover and Woudhuysen contended that the Historia written by Sextus Aurelius Victor, was used as source material by contemporary historians, who widely praised it.
