Friedrich Ebert in the context of "German Revolution of 1918–1919"

The German revolution of 1918–1919, also known as the November Revolution (German: Novemberrevolution), was an uprising started by workers and soldiers in the final days of World War I. It quickly and almost bloodlessly brought down the German Empire. In its more violent second stage, the supporters of a parliamentary republic were victorious over those who wanted a Soviet-style council republic. The defeat of the forces of the far left cleared the way for the establishment of the Weimar Republic. The key factors leading to the revolution were the extreme burdens suffered by the German people during the war, the economic and psychological impacts of the Empire's defeat, and the social tensions between the general populace and the aristocratic and bourgeois elite.

The revolution began in late October 1918 with a sailors' mutiny at Kiel. Within a week, workers' and soldiers' councils were in control of government and military institutions across most of the Reich. On 9 November, Germany was declared a republic. By the end of the month, all of the ruling monarchs, including Emperor Wilhelm II, had been forced to abdicate. On 10 November, the Council of the People's Deputies was formed by members of Germany's two main socialist parties. Under the de facto leadership of Friedrich Ebert of the moderate Majority Social Democratic Party (MSPD), the Council acted as a provisional government that held the powers of the emperor, chancellor and legislature. It kept most of the old imperial officer corps, administration and judiciary in place so that it could use their expertise to address the crises of the moment.

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 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.

The Council of the People's Deputies (German: Rat der Volksbeauftragten, sometimes translated as "Council of People's Representatives" or "Council of People's Commissars") was the provisional government of Germany during the first part of the German Revolution, from 10 November 1918 to 13 February 1919. Formed initially by three members each from Germany's two main socialist parties, it shaped the transition from the Empire to the Weimar Republic.

The Council took over the functions of head of government (chancellor Friedrich Ebert served as chairman of the Council) and issued decrees in place of legislation (Reichstag). In its first days, it introduced a number of important social reforms such as the eight-hour workday and universal suffrage that for the first time gave women the right to vote.

The Majority Social Democratic Party of Germany (German: Mehrheitssozialdemokratische Partei Deutschlands, MSPD) was the name officially used by the Social Democratic Party of Germany (SPD) between April 1917 and September 1922. The name differentiated it from the Independent Social Democratic Party (Unabhängige Sozialdemokratische Partei Deutschlands, USPD), which split from the SPD as a result of the party majority's support of the government during the First World War.

Governments led by the MSPD steered Germany through the German Revolution of 1918–1919 and the first years of the Weimar Republic. They followed a moderate course towards a parliamentary system and often used military force against the radical left groups that wanted a soviet style government. The MSPD introduced important social reforms such as the eight-hour workday and early forms of unemployment and health insurance. The party won more votes than any other in the first two national elections.

The president of Germany (German: Reichspräsident, lit. 'president of the Reich') was the head of state under the Weimar Constitution, which was officially in force from 1919 to 1945, encompassing the periods of the Weimar Republic and Nazi Germany.

The Weimar constitution created a semi-presidential system in which power was divided between president, cabinet and parliament. The president was directly elected under universal adult suffrage for a seven-year term, although Germany's first president, Friedrich Ebert, was elected by the Weimar National Assembly rather than the people. The intention of the framers of the constitution was that the president would rule in conjunction with the Reichstag (legislature) and that his extensive emergency powers would be exercised only in extraordinary circumstances. The political instability of the Weimar period and an increasingly severe factionalism in the legislature, however, led to the president occupying a position of considerable power, legislating by decree and appointing and dismissing governments at will.
