Introduction
Set (as king) is recorded in Manetho's king-list as the usurper who took Egypt's throne after murdering his brother, the king Osiris.

The Usurper's Reign
Set's kingship in Manetho's tradition represents the interruption of rightful succession that Horus's eventual victory resolves, mirroring in historiographic form the same dynamic recorded mythologically in the Egyptian Pantheon project's account of the long contest between Horus and Set. The king-list treats this as a specific, if turbulent, chapter of Egypt's earliest royal history rather than purely religious narrative.
This article records a specific literary or theological role — a king-list entry, a court tale, or a royal legitimation narrative — rather than the deity's or ruler's fuller religious identity, which (where applicable) is covered in the separate Egyptian Pantheon project.
