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.
Letters of Gediminas
The second letter was written on January 25, 1323 to the German cities of Lübeck, Sund, Bremen, Magdeburg, Cologne and other cities in the Holy Roman Empire. Gediminas explained that the Grand Duchy of Lithuania was very tolerant to the Christians, but remained pagan and did not accept Christianity only because of brutal Teutonic Knights. He told about the first letter sent to the pope and his intentions to baptize in the Catholic rite. Gediminas invited knights, squires, merchants, doctors, smiths, wheelwrights, cobblers, skinners, millers, and others to come to the Grand Duchy and practice their trade and faith without any restrictions. The peasants were promised tax exemption for ten years. The merchants were also exempt from any tariffs or taxes. This letter is best known because Vilnius, capital of Lithuania, was mentioned in written sources for the first time. Therefore, 1323 is considered to be the official founding year of Vilnius. Gediminas is considered to be the city's founder even though the city existed years before Gediminas' reign. Also, Vilnius is unambiguously mentioned as the capital city. His invitation notably included German Jews as well as Christians, and its issuance is closely linked to the establishment of the Jewish community in Lithuania.
