United Baltic Duchy
The United Baltic Duchy (German: Vereinigtes Baltisches Herzogtum) was a short-lived client state of the German Empire during the final stages of World War I, proclaimed by political leaders of local Baltic Germans in regions of Courland, Livonia and Estonia, but never fully realized. It was established on 5 November 1918 in Riga, while those regions were still under the military occupation of the Imperial German Army.
