Friedrich Ebert (4 February 1871 – 28 February 1925) was a German politician of the Social Democratic Party of Germany (SPD).

When Ebert was elected as the leader of the SPD after the death of August Bebel, the party members of the SPD were deeply divided because of the party's support for World War I. Ebert supported the Burgfrieden and tried to isolate the war opponents in the party. After the war and the end of the monarchy he served as the first President of Germany from 1919 until his death in office. Before being elected as President, he briefly served as Chancellor during the last months of the German Empire. After he was announced as the new President, the government intervened together with the army and right wing Freikorps against the leftist uprisings, which resulted in the death of several left politicians and ended the partnership of the SPD in government with the Independent Social Democratic Party of Germany (USPD).

After that he changed his politics to a “policy of compensating“ between the left and the right, between the workers and the enterprises. For that he followed a policy of brittle coalitions. This resulted in some problems, for example the SPD agreed during the crisis of 1923 to an extension of the work time without extra payment for the workers, but the conservative parties did not agree to also introduce taxes for the rich as a compensation. His death, which resulted in the monarchist Paul von Hindenburg as his Presidential successor, is seen as an important break in the Weimar Republic, which ended less than a decade later.

Born in Heidelberg as the son of a tailor, he himself was trained as a saddlemaker. He became involved in politics as a trade unionist and Social Democrat, and soon became a leader of the "moderate" wing of the Social Democratic Party, becoming Secretary General in 1905, and party chairman in 1913. In 1912 he was elected as a Member of the Reichstag (parliament of Germany) for the constituency of Elberfeld - Barmen (now part of Wuppertal).

In August 1914, Ebert led the party to vote almost unanimously in favor of war loans, accepting that the war was a necessary patriotic, defensive measure, especially against the autocratic regime of the Czar in Russia. The party's stance, under the leadership of Ebert and other "moderates" like Philipp Scheidemann, in favor of the war with the aim of a compromise peace, eventually led to a split, with those radically opposed to the war leaving the SPD in early 1917 to form the USPD. For similar reasons several left wing members of parliament had already distanced themselves from the party in 1916. Later they called themselves "Spartacists".

When it became clear that the war was lost, a new government was formed by Prince Maximilian of Baden which included Ebert and other members of the SPD in October 1918. Following the outbreak of the German Revolution, Prince Max resigned on 9 November, and handed his office over to Ebert. Prince Max also declared that the Kaiser had abdicated. Ebert favored retaining the monarchy under a different ruler ("If the Kaiser does not abdicate, the social revolution is inevitable. But I do not want it, I even hate it like sin" he had said to Max von Baden on 7 November). On the same day, however, Scheidemann proclaimed the German Republic, in response to the unrest in Berlin and in order to counter a declaration of the "Free Socialist Republic" by Karl Liebknecht later that day. Ebert reproached him: "You have no right to proclaim the Republic!" By this he meant that the decision was to be made by an elected national assembly, even if that decision might be the restoration of the monarchy.

Scheidemann's proclamation ended the German monarchy, and an entirely Socialist provisional government based on workers' councils took power under Ebert's leadership.

Ebert led the new government for the next several months. He used the army under the command of Minister of Defense Gustav Noske and also Freikorps (paramilitary organizations of ex-soldiers) to suppress a Spartacist uprising against the establishment of a parliamentary democracy. Spartacist leaders Rosa Luxemburg and Karl Liebknecht were murdered by members of the Freikorps. When the Constituent Assembly met in Weimar in February, 1919, Ebert was chosen to be the first president of the German Republic.

In 1920, the German workers protected his government from the right wing Kapp Putsch of some Freikorps elements by means of a nationwide general strike. The armed forces Reichswehr remained neutral and did not defend the republic. Nevertheless the government used the army and parts of the Freikorps in order to suppress a communist led rebellion in Germany's main industrial area, the Ruhr district in north west Germany. Thousands of people were killed.

Participants in the Kapp Putsch were treated leniently. The judiciary in the Weimar Republic was "blind in the right eye". Some of the Freikorps already used the swastika as their symbol of resistance against the "red pack" at the time, and many of them as well as right wing members of the Reichswehr would later become influential National Socialists.

Vicious attacks by Ebert's right wing adversaries, including slander and ridicule, were often condoned or even supported by the judiciary when the president turned to the courts. The constant necessity to defend himself against those attacks also undermined his health.
Ebert died on 28 February 1925, aged 54 from untreated appendicitis.

Ebert‘s politics of compensating during the Weimar Republic is seen as an important archetype in the SPD. Today, the SPD associated Friedrich Ebert Foundation, Germany's largest and oldest party affiliated foundation, which, among other things, promotes students of outstanding intellectual ability and personality, is named after Ebert.

Ebert remains a somewhat controversial figure to this day. While the SPD recognizes him as one of the founders and keepers of German democracy whose death in office in February 1925 was a great loss, communists and others on the left argue that he paved the way for fascism by supporting the ultra right Freikorps and their violent suppression of "Marxist" uprisings.

The Freikorps, which consisted of World War I veterans, maintained that the German working class, supported by the SPD, was responsible for Germany's defeat in World War I. The alleged proof of this Dolchstoßlegende was found in a number of strikes during 1917 and 1918 which had partly disrupted production in the Imperial German armaments industry. The aim of the striking workers and their socialist allies was said to have been to turn Imperial Germany into a Soviet Socialist Republic. Most historians, however, say that military defeat was inevitable after the USA had joined the war against Germany. In November 1918, a delegation of members of parliament represented Germany in the ceasefire negotiations at the request of the military leadership after the generals had decided that the war could no longer be won. Critics say that thus the politicians exactly played the role that the military wanted them to play. Ebert later on even co-operated with the generals in order to prevent the country from falling into chaos, as he saw it.

Some historians have defended Ebert's actions as unfortunate but inevitable if the creation of a socialist state on the model that had been promoted by Rosa Luxemburg, Karl Liebknecht and the communist Spartacus Group was to be prevented. Leftist historians like Bernt Engelmann, on the other hand, have argued that organized communism was not yet politically relevant in Germany at the time. However, the actions of Ebert and his Minister of Defense, Gustav Noske, against the insurgents contributed to the radicalization of the workers and to increasing support for communist ideas.

Although the Weimar constitution (which Ebert signed into law in August 1919) provided for the establishment of workers' councils on different levels of society, they did not play a major part in the political life of the Weimar Republic. Ebert always regarded the institutions of parliamentary democracy as a more legitimate expression of the will of the people; workers' councils, as a product of the revolution, were only justified in exercising power for a transitional period. "All power to all the people!" was the slogan of his party, in contrast to the slogan of the far left, "All power to the (workers') councils!". In Ebert's opinion only reforms, not a revolution, could advance the causes of democracy and socialism. So he has been called a traitor by the far left, paving the way for the ascendancy of the far right and even of Hitler, whereas those who think his policies were justified claim that he saved Germany from Bolshevik excesses.

Philipp Scheidemann (26 July 1865, Kassel, Hesse - Kassel – 29 November 1939 Copenhagen) was a German Social Democratic politician, who proclaimed the Republic on 9 November 1918, and who became the second Chancellor of the Weimar Republic.

He was by trade a printer, but in 1895 took to editing socialist newspapers, first at Giessen and afterwards successively at Nuremberg, Offenbach and Kassel. Scheidemann became a Reichstag delegate from Solingen for the Social Democrats in 1903, and soon rose to be one of the principal leaders of the party. During the First World War, Scheidemann, along with Friedrich Ebert was leader of the majority faction of the party, which continued to vote for war credits, limiting his opposition to the war to urging the negotiation of a compromise peace. In June 1918, Scheidemann was elected vice president of the Reichstag. When the Social Democrats were included in the cabinet for the first time in Prince Max of Baden's government in October 1918, Scheidemann entered the government as a minister without portfolio.

Following the Kaiser's abdication on November 9, Prince Max resigned in favor of Ebert. Although the new government intended to support a constitutional monarchy, probably in the person of one of the Kaiser's grandsons, Scheidemann, concerned in the face of a possible workers' revolution in Berlin, unilaterally proclaimed the Republic from a balcony in the Reichstag building. The timing of this proclamation was probably due to the expectation of a similar proclamation of a "Workers' Republic" by the communists led by Karl Liebknecht, which indeed followed a couple hours later.

Scheidemann continued to serve as a leader in the Provisional Government which followed for the next several months, and following the meeting of the National Assembly in Weimar in February 1919, Ebert was appointed Reich President, and Scheidemann became Chancellor, in the Weimar Coalition with the German Democratic Party and the Catholic Center Party. Scheidemann resigned in June along with the DDP owing to disagreement with the Treaty of Versailles, and never again served in the government, although he remained active in politics, serving as Mayor of Kassel (1920 - 1925), and then again as a Reichstag delegate, where he exposed military opposition to the Republic. Scheidemann went into exile following the Nazi takeover in 1933, and died in Denmark shortly after the outbreak of the Second World War.
