Coat of arms of Schleswig

The coat of arms of Schleswig or Southern Jutland (Danish: Sønderjylland or Slesvig) depicts two blue lions in a golden shield. It is the heraldic symbol of the former Duchy of Schleswig, originally a Danish province but later disputed between Danes and Germans. The region has been divided between Germany and Denmark since 1920 and the symbol consequently appears in official heraldry in both countries. It is derived from the national coat of arms of Denmark and has been dated to the middle of the 13th century, first known from the arms of Erik Abelsøn, Duke of Schleswig. Throughout the ages, the design has featured both crowned and uncrowned lions, the lions have occasionally been accompanied by hearts and usage between lions and leopards has shifted. The far most common version was to omit both crowns and hearts and this version has been used exclusively for several centuries.

The blazon in heraldic terms is: Or, two lions passant in pale Azure armed Or langued Gules.

The unmodified arms of Schleswig is represented in the coat of arms of Denmark's royal family. The symbol has been located in the top-right corner since 1819 as specified by royal decree. The current version was specified by royal decree on July 5, 1972.

A modified form of the symbol was used by the South Jutland County from 1980 until the county was dissolved effective January 1, 2007. The county originally wished to use the historic arms, but official authorisation was withheld to avoid confusion with both the royal coat of arms and the arms of the German Bundesland Schleswig-Holstein. This modified version showed the two lions jointly holding a Danish pennant. This was inspired by the medieval seal of Eric of Pomerania in which the three lions jointy hold the Danish flag.
