- Saxon Wars: King Charlemagne leads a Frankish expedition from the Middle Rhine into disputed territory lost by the Franks in 695. He starts a campaign against the Saxons and seizes Eresburg, destroying the Irminsul (Saxon sacred tree) near Paderborn. Charlemagne devastates several major Saxon strongholds, and forces them to retreat beyond the Weser River. After negotiating with some Saxon nobles and obtaining hostages, he installs a number of garrisons.
