Saxon paganism, sometimes known as Continental Saxon paganism or Saxon heathenism, refers to the religion of the Saxons before their Christianization in the wake of the Saxon Wars (772–804) of Charlemagne. Distinct from its closely related Anglo-Saxon counterpart, Saxon paganism was a polytheistic belief system and part of the larger Continental Germanic mythology, with a focus on the sacredness of pillar-like objects (such as Irminsul) and sacred groves, many of which were destroyed.
After Christianization, monasteries repurposed Saxon beliefs and values in new Christian literature, such as the Old Saxon epic poem Heliand, and used the region as a barrier between Christendom and the Slavic and Norse pagans to the north and east. Reportedly, paganism continued among the Saxons until the 12th century.
