German Revolution of 1918–1919 in the context of "Russian Revolution"

The Kingdom of Prussia (German: Königreich Preußen, pronounced [ˈkøːnɪkʁaɪç ˈpʁɔʏsn̩] ) was a German state that existed from 1701 to 1918. It played a significant role in the unification of Germany in 1871 and was a major constituent of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin.

The kings of Prussia were from the House of Hohenzollern. The polity of Brandenburg-Prussia, predecessor of the kingdom, became a military power under Frederick William, Elector of Brandenburg, known as "The Great Elector". As a kingdom, Prussia continued its rise to power, especially during the reign of Frederick II "the Great". Frederick the Great was instrumental in starting the Seven Years' War (1756–1763), holding his own against Austria, Russia, France and Sweden and establishing Prussia's dominant role among the German states, as well as establishing the country as a European great power through the victories of the powerful Prussian Army. Prussia made attempts to unify all the German states (excluding the German cantons in Switzerland) under its rule, and whether Austria would be included in such a unified German domain became an ongoing question. After the Napoleonic Wars led to the creation of the German Confederation, the issue of unifying the German states caused the German revolutions of 1848–1849, with representatives from all states attempting to unify under their own constitution. Attempts to create a federation remained unsuccessful and the German Confederation collapsed in 1866 when the Austro-Prussian War ensued between its two most powerful member states.

The revolutions of 1917–1923 were a revolutionary wave that included political unrest and armed revolts around the world inspired by the success of the Russian Revolution and the disorder created by the aftermath of World War I. The uprisings were mainly socialist or anti-colonial in nature. Most socialist revolts failed to create lasting socialist states. The revolutions had lasting effects in shaping the future European political landscape, with, for example, the collapse of the German Empire and the dissolution of Austria-Hungary.

World War I mobilized millions of troops, reshaped political powers and drove social turmoil. From the turmoil outright revolutions broke out, massive strikes occurred, and many soldiers mutinied. In Russia, the Tsar Nicholas II abdicated during the February Revolution. The short-lived liberal Russian Provisional Government was formed, but it was overthrown by the Bolsheviks in the October Revolution, which triggered the bloody Russian Civil War. Many French soldiers mutinied in 1917 and refused to engage the enemy. In Bulgaria, many troops mutinied, and the Bulgarian Tsar stepped down. Mass strikes and mutinies occurred in Austria-Hungary, and the Habsburg monarchy collapsed. In Germany, the November Revolution led to the end of the German Empire. Italy faced various mass strikes. Turkey experienced a successful war of independence. Ireland was partitioned and the Irish Free State was created. Across the world, various other protests and revolts occurred.

During World War I, the German Empire was one of the Central Powers. It began participation in the conflict after the declaration of war against Serbia by its ally, Austria-Hungary. German forces fought the Allies on both the eastern and western fronts, although German territory itself remained relatively safe from widespread invasion for most of the war, except for a brief period in 1914 when East Prussia was invaded. A tight blockade imposed by the Royal Navy caused severe food shortages in the cities, especially in the winter of 1916–17, known as the Turnip Winter. At the end of the war, Germany's defeat and widespread popular discontent triggered the German Revolution of 1918–1919 which overthrew the monarchy and established the Weimar Republic.

The German Emperor (German: Deutscher Kaiser, pronounced [ˈdɔʏtʃɐ ˈkaɪzɐ] ) was the official title of the head of state and hereditary ruler of the German Empire. A specifically chosen term, it was introduced with the 1 January 1871 constitution and lasted until the abdication of Wilhelm II was announced on 9 November 1918. The Holy Roman Emperor is sometimes also called "German Emperor" when the historical context is clear, as derived from the Holy Roman Empire's official name of "Holy Roman Empire of the German Nation" from 1512.

Following the revolution of 1918, the head of state was the president of the Reich (German: Reichspräsident), beginning with Friedrich Ebert.

The proclamation of the republic in Germany took place in Berlin twice on 9 November 1918, the first at the Reichstag building by Philipp Scheidemann of the Majority Social Democratic Party of Germany (MSPD) and the second a few hours later by Karl Liebknecht, the leader of the Marxist Spartacus League, at the Berlin Palace.

In the German Revolution of 1918–1919, during which Social Democrats and Spartacists were among the groups that fought to determine the country's future form of government, it was the MSPD and the ideas of the bourgeois-democratic parties that prevailed over the Spartacists and their more radical idea of a soviet-style republic. The German Empire was transformed from a monarchy into a parliamentary democratic republic with a liberal constitution. Scheidemann's speech marked the point at which the Empire could be said to have ended and the Weimar Republic born.

The Social Democratic Party of Germany (German: Sozialdemokratische Partei Deutschlands [zoˈtsi̯aːldemoˌkʁaːtɪʃə paʁˌtaɪ ˈdɔʏtʃlants], SPD [ɛspeːˈdeː] ) is a social democratic political party in Germany. It is one of the major parties of contemporary Germany. Lars Klingbeil has been the party's leader since the 2021 SPD federal Party convention together with Bärbel Bas, who joined him in June 2025. After losing the 2025 federal election, the party is part of the Merz government as the junior coalition partner. The SPD is a member of 12 of the 16 German state governments and is a leading partner in seven of them.

The SPD was founded in 1875 from a merger of smaller socialist parties, and grew rapidly after the lifting of Germany's repressive Anti-Socialist Laws in 1890 to become the largest socialist party in Western Europe until 1933. In 1891, it adopted its Marxist-influenced Erfurt Program, though in practice it was moderate and focused on building working-class organizations. In the 1912 federal election, the SPD won 34.8 percent of votes and became the largest party in the Reichstag, but was still excluded from government. After the start of the First World War in 1914, the party split between a pro-war mainstream and the anti-war Independent Social Democratic Party, some members of which later formed the Communist Party of Germany (KPD). The SPD played a leading role in the German revolution of 1918–1919 and in the foundation of the Weimar Republic. The SPD politician Friedrich Ebert served as the first president of Germany from 1919 to 1925.
