49 BCE marks the start of Assassin’s Creed Origins’ main historical storyline.
Assassin’s Creed Origins begins in Ptolemaic Egypt in 49 BCE, when Bayek of Siwa returns home and becomes entangled in a conspiracy involving powerful figures. The story follows Bayek and Aya as they investigate enemies whose organization eventually develops into the Hidden Ones, the predecessor of the Assassin Brotherhood.
The date places the game during the final decades of the Ptolemaic Kingdom. Cleopatra VII, Julius Caesar, and Ptolemy XIII are among the historical figures connected to the narrative. The game moves across regions including Siwa, Alexandria, Memphis, and Cyrene.
The date is often confused with 44 BCE, the year Julius Caesar was assassinated in Rome. Origins starts earlier, during the Roman intervention in the Egyptian succession conflict. Its historical campaign covers several years rather than depicting only one calendar year.
