The date of the text is uncertain, but its administrative language is certainly Carolingian. It is most probably of the 9th century. It has been connected with Charlemagne's codification program of 802–803, which also produced the Lex Thuringorum, Lex Frisionum and Lex Saxonum. If so, this suggests that the Ewa should also be associated with a land or people beyond the Rhine. Collectively, these four codes have been called karolingischen Stammesrechte ("Carolingian tribal laws"). Étienne Baluze thought the Ewa was the "forty-six articles concerning matters of necessity to God's church and the Christian people" issued at Aachen in 813 according to the Chronicle of Moissac. This thesis, however, is untenable.
