The 1919 Ceasefire of Copenhagen was the treaty that de-facto ended the Weltkrieg, although it did not formally conclude until the Peace with Honour in 1921. It provided for the return of occupied Entente and Central Powers territory with the exception of Qingdao, the repatriation of prisoners, and Entente diplomatic recognition of the Central Powers' gains from its former members.


After the fall of France, Britain had clung to the belief that a decisive naval victory could break Germany and reverse the tide of the war. After the Second Battle of Jutland ended in a miserable stalemate, popular will to continue the war vanished. Germany's offer of a white peace was grimly accepted, and diplomatic feelers were put out to find a willing neutral territory to sign a ceasefire in. Denmark was deemed the most convenient, and in December the representatives of the two alliances arrived by boat in Copenhagen and met in Rosenborg Castle. During the first round of negotiations, Japan claimed their "13 Demands" with China superseded Germany's lease of territory on the Shandong Peninsula and refused to evacuate it. When the British failed to support their claim, the delegation walked out. Nonetheless, the ceasefire was signed by the remaining two powers on the morning of Christmas Eve, bringing an end to half a decade of bloodshed.
