The Collapse of the Imperial German Army occurred in the latter half of 1918 and led to the German Revolution of 1918–1919, the Armistice and the eventual end of the war following the signing of the Treaty of Versailles. Dissatisfaction, desertions, mass surrenders and mutinies had spread amongst the Imperial Germany Army following the defeat of the Spring Offensive. However it was only with the Kiel mutiny that a more determined initiative towards revolution emerged.
