Assassin's Creed Shadows, the latest installment in this sprawling franchise, might seem chronologically misplaced. Set in feudal Japan, it sits in the middle of the series' historical timeline. That's because Assassin's Creed doesn't follow a strict chronological order; it leaps through time, exploring pivotal historical events from the Peloponnesian War in Ancient Greece to the brink of World War I.
With 14 mainline games and counting, the timeline is undeniably complex. IGN has meticulously pieced together the centuries-spanning narrative, outlining the overarching story and how each game fits within the larger tapestry. The result is this chronologically ordered timeline, highlighting key events in the Assassin's Creed universe.
The Isu Era: 75,000 BCE
Before we delve into the historical timeline, a bit of lore is necessary. Eons ago, a highly advanced civilization of god-like beings, known as the Isu, ruled Earth. They created humanity to serve as their slaves, maintaining control through powerful artifacts called the Apples of Eden. Humanity, naturally resistant to enslavement, rebelled. Eve and Adam stole an Apple of Eden, sparking a decade-long war that ended abruptly with a devastating solar flare, wiping out the Isu and leaving humanity to inherit the Earth.
