The Isted Lion (Danish: Istedløven, German: Flensburger Löwe or Idstedt Löwe) is a Danish war monument originally intended as a monument of the Danish victory over Schleswig-Holstein in the Battle of Isted (July 25, 1850) — at its time the largest battle in Scandinavian history. Others perceived it more as a memorial for the Danish dead in the battle.
Originally erected in Flensburg, Schleswig, it was moved to Berlin by Prussian authorities and remained there until 1945. It was returned to Denmark as a gift from the United States Army and is currently located at Søren Kierkegaards Plads in Copenhagen. A number of politicians have suggested that it be returned to Germany but the issue remains controversial.
Following the Danish victory over Schleswig-Holstein in the First War of Schleswig (1848–51), Danish sculptor Herman Wilhelm Bissen was commissioned to create a monument to the ordinary Danish soldier, likely the first example of a Tomb of the Unknown Soldier. This monument Landsoldaten (the Foot Soldier) was unveiled in Fredericia in 1858.
