While written laws like the lex salica governed everyday life, the Carolingians also issued decrees from time to time, called capitularies. Capitularies are legal documents, so named because they are divided into chapters or articles called ‘capitula.’ Capitularies were issued by the king, and describe and explain legal obligations of the king’s subjects. It is through capitularies that the flavor of royal rule can be known. “While the decisive influence of Charlemagne on the institutions of the Frankish monarchy is well known, what is more obscure… is the manner in which Charlemagne wielded this influence. This was done chiefly through the capitularies… by which the Carolingian monarchs issued legislative and administrative provisions.”1.Ganshof, Carolingians, “The impact of Charlemagne on the institutions of the Frankish realm,” p.143.
There are about 100 capitularies that have come down to modern times. Of these, maybe twenty-five have been translated into English, primarily by King and Loyn & Percival. I find Loyn & Percival’s translations a little clearer to read, although King provides more background on each capitulary.
