Liutprand was the king of the Lombards from 712 to 744 and is chiefly remembered for his multiple phases of law-giving, in fifteen separate sessions from 713 to 735 inclusive, and his long reign, which brought him into a series of conflicts, mostly successful, with most of Italy. He is often regarded as the most successful Lombard monarch, notable for the Donation of Sutri in 728, which was the first accolade of sovereign territory to the Papacy.

Paul the Deacon, also known as Paulus Diaconus, Warnefridus, Barnefridus, or Winfridus, and sometimes suffixed Cassinensis, was a Benedictine monk, scribe, and historian of the Lombards.
