 appealed to Pope Honorius III to have his oath repealed, a request the Pope granted. In 1226, Valdemar attacked the nobles of Holstein, and initially, had success.

On July 22, 1227 the two armies clashed at Bornhöved in Holstein in the second Battle of Bornhöved. The battle ended in a decisive victory for Adolphus IV of Holstein. During the battle the troops from Dithmarschen abandoned the Danish army and joined Adolphus' army. In the following peace, Valdemar II relinquished his conquests in Holstein for good and Holstein was permanently secured to the house of Schauenburg.

King Valdemar II, who had retained the former imperial March north of the Eider, in 1232 erected Schleswig as a duchy for his second son, Abel. Holstein on the other hand, after the death of Adolphus IV in 1261, was split up into several countships by his sons and again by his grandsons (1290): the lines of Holstein-Kiel (1261–1390), Holstein-Pinneberg and Schaumburg (1290–1640) south of the Elbe, Holstein-Plön (1290–1350), Holstein-Rendsburg (1290–1459), and at times also Holstein-Itzehoe (1261–1290) and Holstein-Segeberg (1273–1315), and again 1397–1403), all named after the comital residential cities.

14th century
The connection between Schleswig and Holstein became closer during the 14th century as the ruling class and accompanying colonists intensely populated the Duchy Schleswig. Local lords of Schleswig had already early paid attention to keep Schleswig independent from the Kingdom of Denmark and to strengthen ties to Holstein within the Holy Roman Empire. This tradition of autonomy showed itself in future politics for centuries to come.

The rivalry, sometimes leading into war between the kings of Denmark and the Abelian dukes of Schleswig was expensive, and Denmark had to finance it through extensive loans. The Dukes of Schleswig were allied with the Counts of Holstein, who happened to become the main creditors of the Danish Crown, too, in the reign of the utterly incompetent king Christopher II of Denmark.

 King Valdemar II, who had retained the former imperial March north of the Eider, in 1232 erected Schleswig as a duchy for his second son, Abel.
