Assassin's Creed Shadows marks the latest addition to the expansive Assassin's Creed series, setting its scene in the rich backdrop of feudal Japan. This choice places it squarely in the middle of the franchise's historical timeline, which famously jumps through time rather than progressing linearly. From the ancient Peloponnesian War in Greece to the dawn of the First World War, each installment delves into pivotal moments in history.
With a total of 14 mainline games and counting, the Assassin's Creed universe has woven an increasingly intricate tapestry of events and narratives. To help fans navigate this complexity, IGN has meticulously analyzed every piece of lore to construct a comprehensive timeline. This timeline not only chronicles key events in chronological order but also ties together the overarching narrative and the connections between each game.

Before diving into the historical timeline, it's essential to understand the foundational lore. In the distant past, a highly advanced civilization known as the Isu ruled the Earth.

However, humans, led by Adam and Eve, rebelled after stealing an Apple, sparking a decade-long war. This conflict ended abruptly when a solar flare devastated the Isu, leaving humanity to rise from the ashes.
