In which century is Assassin's Creed Valhalla primarily set?

Assassin's Creed Valhalla is primarily set in the 9th century.

The game follows Eivor, a Viking raider who leaves Norway and settles in England. Its main historical period begins in 872 CE and covers the Viking expansion and conflicts among Anglo-Saxon kingdoms during the late ninth century.

The story includes historical figures such as Alfred the Great, king of Wessex. It also moves between Norway and England, with additional mythological sequences that draw on Norse traditions. Despite those fantasy elements, the principal historical setting remains the ninth century.

The date is sometimes confused with the eleventh century because the Viking Age continued into that period and because other Viking-themed media use later settings. Valhalla's specific campaign begins in the late 800s, making the ninth century the correct broad time period.
