Charlemagne launched his first major campaign into Saxony, capturing the fortress of Eresburg and destroying the Irminsul, a prominent Saxon cult object/site, signaling an intent to conquer and Christianize the region.
Charlemagne convened leading secular and ecclesiastical figures at Paderborn during the Saxon conflict, pairing military pressure with ecclesiast organization-building (including churches/mission infrastructure) to consolidate Frankish control.
Charlemagne campaigned deeper into Saxon territory, reaching the Elbe River and receiving submissions/hostages; these advances extended Frankish influence while provoking repeated rebellions.
A Saxon uprising led by Widukind defeated a Frankish detachment at the Battle of Süntel, killing key Frankish commanders and escalating Charlemagne’s reprisals.
A harsh capitulary commonly known as the Capitulatio de partibus Saxoniae set severe penalties to enforce Christianization and Frankish order in Saxony; scholars debate its precise dating (often placed around 782 or 785).
After suppressing the 782 revolt, Charlemagne ordered the execution of 4,500 Saxons at Verden (often called the Massacre of Verden), an episode recorded in Frankish annals and emblematic of the war’s brutality.
In 783, Charlemagne defeated Saxon forces in a series of engagements, including fighting near Detmold (Theotmalli) and the Battle on the Hase near modern Osnabrück, helping reassert Frankish momentum after earlier setbacks.
Saxon leader Widukind submitted and accepted Christian baptism (traditionally associated with Attigny), a major political turning point even though resistance continued in other areas.
Despite Widukind’s submission, a major renewed revolt broke out in 793, showing that Christianization and Frankish governance remained contested, especially under burdens like tithe obligations and coercive policies.
At Aachen, Charlemagne promulgated the Capitulare Saxonicum (dated 5 Kalends of November = 28 October 797), replacing many death penalties with fines and aiming to stabilize Saxony through a more integrative legal approach.
Frankish allies, the Obotrites, defeated the Nordalbingian Saxons at Bornhöved (Sventanafeld) in 798, a major blow to northern Saxon resistance and a step toward ending the long conflict.
The Lex Saxonum (commonly dated to 802) codified Saxon customary law within the Frankish realm, reflecting a shift from emergency rule toward longer-term legal integration.
In 804, Charlemagne ended the last major resistance by deporting large numbers of Nordalbingian Saxons and redistributing their lands (notably to loyal Obotrite allies), conventionally marking the end of the Saxon Wars.
