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
As a result of the Great Retreat during World War I, Germany occupied the entire territory of Lithuania and Courland by the end of 1915. A new administrative entity, Ober Ost, was established. Lithuanians lost all political rights they had gained: personal freedom was restricted, and at the beginning the Lithuanian press was banned. However, the Lithuanian intelligentsia tried to take advantage of the existing geopolitical situation and began to look for opportunities to restore Lithuania's independence. On 18–22 September 1917, the Vilnius Conference elected the 20-member Council of Lithuania. The council adopted the Act of Independence of Lithuania on 16 February 1918 which proclaimed the restoration of the independent state of Lithuania governed by democratic principles, with Vilnius as its capital. The state of Lithuania which had been built within the framework of the Act lasted from 1918 until 1940.
Following the capitulation of Germany in November 1918, the first Provisional Constitution of Lithuania was adopted and the first government of Prime Minister Augustinas Voldemaras was organized. At the same time, the army and other state institutions began to be organized. Lithuania fought three wars of independence: against the Bolsheviks who proclaimed the Lithuanian Soviet Socialist Republic, against the Bermontians, and against Poland. As a result of the staged Żeligowski's Mutiny in October 1920, Poland took control of Vilnius Region and annexed it as Wilno Voivodeship in 1922. Lithuania continued to claim Vilnius as its "de jure" capital and relations with Poland remained particularly tense and hostile for the entire interwar period. In January 1923, Lithuania staged the Klaipėda Revolt and captured Klaipėda Region (Memel territory) which was detached from East Prussia by the Treaty of Versailles. The region became an autonomous region of Lithuania.
