Capitulatio de partibus Saxoniae
Capitulatio de partibus Saxoniae (Latin, variously translated as 'Ordinances concerning Saxony' or the 'Saxon Capitularies' or 'Capitulary of Paderborn') was a legal code issued by Charlemagne and promulgated amongst the Saxons during the Saxon Wars. Traditionally dated to Charlemagne's 782 campaign, and occasionally to 785, the much later date of 795 is also considered possible.
