In the final days of
World War I, when it became clear that Germany was facing defeat, the
revolution of 1918–1919 broke out and brought down the
German Empire and all of Germany's royal houses. The revolution began in late October 1918 when
rebellious sailors at Kiel set up a
workers' and soldiers' council and in early November spread the revolt across the rest of Germany. Emperor
Wilhelm II fled to Holland on 10 November, and councils quickly took power from the existing military, royal and civil authorities with little resistance or bloodshed. The revolution followed the same pattern when it reached the Thuringian states on 8 November. Workers' and soldiers' councils took control in all seven states, and by 23 November the last of the ruling monarchs (Prince
Günther Victor, for
Schwarzburg-Sondershausen) had abdicated. The revolution in the Thuringian states unfolded for the most part without violence and often within the framework of the states' existing constitutions. Typical of the sequence of events is the
Free State of Saxe-Altenburg, where a workers' and soldiers' council took control on 9 November. Four days later,
Duke Ernst II abdicated under pressure from both the council in
Altenburg and the events in Germany as a whole. The state ministry (government) was then expanded to include a representative of the moderate left
Social Democratic Party (SPD), and it scheduled an election for a new
Landtag (state parliament) under universal and equal voting rights. The SPD won an absolute majority of the seats, and the
Landtag went on to pass an interim republican constitution for the new Free State of Saxe-Altenburg in April 1919. The following month it ratified the preliminary agreement on the unification of the
Thuringian states that it had helped work out with the other states, and on 1 May 1920 Saxe-Altenburg ceased to exist when it became part of the new State of Thuringia. In
Saxe-Coburg and Gotha, the revolution led to the Duchy breaking apart. In the
Coburg region, the revolution played out quietly, much as it did in Saxe-Altenburg and the other Thuringian states, but in
Gotha events were more turbulent. It was the only region within the Thuringian states where the radical left
Independent Social Democratic Party (USPD) won a majority of the seats when it elected a new
Landtag. The USPD favored the establishment of a
council (soviet) republic, whereas the SPD, which dominated in Coburg, wanted a parliamentary republic. The election campaign in
Gotha was overshadowed by the occupation of the city by
Freikorps units that supported the SPD-led government in Berlin. They were sent in to disarm workers in Gotha who were seen as a potential threat to the
Weimar National Assembly, which was meeting nearby. The occupation led to eight days of street fighting between the
Freikorps and workers before the troops withdrew. In spite of the USPD's dominance, Gotha's
Landtag rejected a draft constitution that established a council republic and instead opted for a parliamentary republic. During the right-wing
Kapp Putsch in Berlin in March 1920, striking workers in Gotha armed themselves and set up a 40-member executive council (). The government sent a
Reichswehr unit to the city and serious clashes broke out, with 127 deaths counted before the fighting ended on 19 March. On 10 April the Berlin government implemented a
Reichsexekution against Saxe-Gotha to resolve its government crisis. A state of emergency was imposed, a Reich commissioner took control in the Free State, the
Landtag was dissolved and a new election held in which the USPD, although still the largest party, lost its absolute majority. Gotha went on to become part of the new state of Thuringia when it was formed on 1 May 1920. In Coburg, the people voted in a referendum against joining Thuringia and instead merged into
Bavaria on 1 July 1920. The two former Reuss principalities merged into the
People's State of Reuss in April 1919 before joining Thuringia in 1920. == Founding ==
