On 19 June, Chancellor Philipp Scheidemann resigned rather than sign the treaty and was followed by Brockdorff-Rantzau and other members of the government, leaving Germany without a cabinet or peace delegation. After being advised by Field Marshal Paul von Hindenburg that Germany was in no condition to resume the war, President Friedrich Ebert and the new Chancellor, Gustav Bauer, recommended that the Weimar National Assembly ratify the treaty. The Assembly did so by a large majority, and Clemenceau was informed nineteen minutes before the deadline expired. Germany unconditionally signed the peace treaty on 22 June. Initially, Article 231 was 
Title: Treaty of Versailles (1871)
Content:  The Treaty of Versailles of 1871 ended the Franco-Prussian War and was signed by Adolphe Thiers of the French Third Republic and Otto von Bismarck of the newly-formed German Empire on 26 February 1871. A preliminary treaty, it was used to solidify the initial armistice of 28 January between the powers. It was ratified by the Treaty of Frankfurt on 10 May of the same year which made the decline of French power obvious to the rest of the continent, and at the same time demonstrated the strength of a unified German empire. Paris's governing body, the Government of National Defense had made an armistice, effective from 28 January, by surrendering to the Germans to end the siege of Paris; Jules Favre, a prominent French politician, did so, meeting with Bismarck in Versailles to sign the armistice. Adolphe Thiers emerged by the time of a formal treaty as the new French leader as the country began reconstructing its government.

Content:  The Treaty of Versailles (Traité de Versailles; Versailler Vertrag, ) was the most important of the peace treaties that brought World War I to an end. The Treaty ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919 in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war. The other Central Powers on the German side signed separate treaties. Although the armistice, signed on 11 November 1918, ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to

The National Assembly voted in favour of signing the treaty by 237 to 138, with five abstentions (there were 421 delegates in total). This result was wired to Clemenceau just hours before the deadline. Foreign minister Hermann Müller and colonial minister Johannes Bell travelled to Versailles to sign the treaty on behalf of Germany. The treaty was signed on 28 June 1919 and ratified by the National Assembly on 9 July by a vote of 209 to 116.

Content:  In June 1919, the Allies declared that war would resume if the German government did not sign the treaty they had agreed to among themselves. The government headed by Philipp Scheidemann was unable to agree on a common position, and Scheidemann himself resigned rather than agree to sign the treaty. Gustav Bauer, the head of the new government, sent a telegram stating his intention to sign the treaty if certain articles were withdrawn, including Articles 227, 230 and 231. In response, the Allies issued an ultimatum stating that Germany would have to accept the treaty or face an invasion of Allied forces

Content:   On 29 April, the German delegation under the leadership of the Foreign Minister Ulrich Graf von Brockdorff-Rantzau arrived in Versailles. On 7 May, when faced with the conditions dictated by the victors, including the so-called "War Guilt Clause", von Brockdorff-Rantzau replied to Clemenceau, Wilson and Lloyd George: "We can sense the full force of hatred that confronts us here. ... You demand from us to confess we were the only guilty party of war; such a confession in my mouth would be a lie." Because Germany was not allowed to take part in the negotiations, the German government issued a protest against

On 28 June 1919, the fifth anniversary of the assassination of Archduke Franz Ferdinand (the immediate impetus for the war), the peace treaty was signed. The treaty had clauses ranging from war crimes, the prohibition on the merging of the Republic of German Austria with Germany without the consent of the League of Nations, freedom of navigation on major European rivers, to the returning of a Koran to the king of Hedjaz.
Title: Black Horror on the Rhine
Content:   There was political turmoil in Germany when it came to signing the Versailles Treaty. In June 1919 Philipp Scheidemann, the first democratically elected Chancellor of Germany, resigned when faced with the Allied ultimatum that it should be signed with none of the changes the German government had requested. His was succeeded as Chancellor by Gustav Bauer. The terms of the treaty meant that the counter-revolutionary Freikorps which the Weimar government had created to crush the revolutionary movement faced being disbanded. Rather than submit to this, Wolfgang Kapp gathered significant Army officers around him and launched the Kapp Putsch. The success of the Putsch would open up a possibility 
Title: Treaty of Versailles (1871)
Content:  While the French government deteriorated, Bismarck succeeded in achieving the unification of most of Germany (aside from Austria) on January 18, 1871 creating the German Empire. King Wilhelm I of Prussia was declared Kaiser of the newly created empire in the Hall of Mirrors in the Versailles Palace. The new German command structure wanted to sign a peace treaty to gain France's colonial possessions; however, Bismarck opted for an immediate truce as his primary reason for war, German unification, had already been accomplished. He was concerned that further violence would render more German casualties and draw French resentment. He was also wary of drawing attention from other European nations, fearing that they might be moved to intervene if the new German state appeared power-hungry. Both sides were eager to sign a treaty by the beginning of February 1871.

Content:  Germany were being passed through. The Treaty of Versailles was to come into force so soon as it had been ratified by Germany and by three of the principal Allied and Associated Powers; and since it had now been ratified by Germany and by France, the United Kingdom, Italy, and Japan (though not by the United States), it was only necessary that the protocols certifying these facts should be signed by the parties to the treaty, and formal peace would then exist between the Allied Powers and Germany. The Supreme Council of the Allies decided that this final ceremony should take
