Codex Holmiensis C 37 contains the oldest manuscript of the Danish Code of Jutland (Danish: Jyske Lov), a civil code enacted under Valdemar II of Denmark. The code covered Funen, Jutland, and Schleswig. Prior to the adoption of the Jutlandic, Zealandic and the Scanian laws, there had been no uniformity of laws throughout settlements in Denmark. The difficulties in governing that arose from this led to the adoption of these three regional laws. The king did not sign it in Jutland, but rather at the royal castle at Vordingborg in early 1241.
The Code was succeeded by Christian V's Danish Code of 1683; however in certain parts of Schleswig parts of the Code were used until the arrival of Bürgerliches Gesetzbuch in 1900.
