Kingdom of Lithuania (1918)
The Kingdom of Lithuania was a short-lived constitutional monarchy created towards the end of World War I when Lithuania was under occupation by the German Empire. The Council of Lithuania declared Lithuania's independence on February 16, 1918, but the Council was unable to form a government, police, or other state institutions due to the continued presence of German troops. The Germans presented various proposals to incorporate Lithuania into the German Empire, particularly Prussia. The Lithuanians resisted this idea and hoped to preserve their independence by creating a separate constitutional monarchy. On June 4, 1918, they voted to offer the Lithuanian throne to the German noble Wilhelm, 2nd Duke of Urach. Duke Wilhelm accepted the offer in July 1918 and took the name Mindaugas II. However, he never visited Lithuania. His election stirred up controversy, divided the Council, and did not achieve the desired results. As Germany was losing the war and was engulfed in the German Revolution, Lithuania suspended its decision to invite Duke William on November 2, 1918, thereby ending his short reign.
Lithuania Minor
Lithuania declared its independence from Russia in 1918 during World War I. Some Prussian Lithuanian activists signed the Act of Tilsit, demanding unification of Lithuania Minor and Lithuania major into a single Lithuanian state, thus detaching the areas of East Prussia from Germany which were inhabited by Prussian Lithuanians. This claim was supported by the Lithuanian government. The part north of the Neman River up to Memel was separated from Germany by the Treaty of Versailles in 1920, and was called the Memel Territory. It was made a protectorate of the Entente States, in order to guarantee port rights to Lithuania and Poland. In January 1923, the Klaipėda Revolt took place and Klaipėda region was annexed to Lithuania in 1923 under violation of the Treaty of Versailles. The subsequent incorporation of the territory brought economic prosperity to Lithuania, with the region accounting for 30% of the country's economy. However, the region's economic significance declined after economic sanctions were imposed by Nazi Germany in 1933.
