The Kingdom of Lithuania was an attempt to establish an independent constitutional Lithuanian monarchy in February 1918. It was created towards the end of World War I when Lithuanian-speaking lands were under military occupation by the German Empire. The state was officially dissolved in November 1918.

The Supreme Commander of All German Forces in the East, also known by its German abbreviation as Ober Ost, was both a high-ranking position in the armed forces of the German Empire as well as the name given to the occupied territories on the German section of the Eastern Front of World War I, with the exception of Poland. It encompassed the former Russian governorates of Courland, Grodno, Vilna, Kovno and Suwałki. It was governed in succession by Paul von Hindenburg and Prince Leopold of Bavaria. It was abandoned after the end of World War I.
