Charlemagne never existed, is a fictional character

Phantom time hypothesis is a theory developed by Heribert Illig which suggests that the Early Middle Ages (614–911 CE) never occurred, meaning that all artifacts attributed to this time period were from other times, and all historical figures were outright fabrications.

One consequence of Illig's hypothesis is that Charlemagne never existed but is a fictional character. The vast majority of historians believe this theory to be complete fiction, as all cited evidence can be considered circumstantial.
