Wilhelm II in the context of "German revolution of 1918–1919"

The Treaty of Versailles was a peace treaty signed on 28 June 1919. As the most important treaty of World War I, it ended the state of war between Germany and most of the Allied Powers. It was signed 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 of 11 November 1918 ended the actual fighting, and agreed certain principles and conditions including the payment of reparations, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. Germany was not allowed to participate in the negotiations before signing the treaty.

The treaty required Germany to disarm, make territorial concessions, extradite alleged war criminals, agree to Kaiser Wilhelm being put on trial, recognise the independence of states whose territory had previously been part of the German Empire, and pay reparations to the Entente powers. The most critical and controversial provision in the treaty was: "The Allied and Associated Governments affirm and Germany accepts the responsibility of Germany and her allies for causing all the loss and damage to which the Allied and Associated Governments and their nationals have been subjected as a consequence of the war imposed upon them by the aggression of Germany and her allies." The other members of the Central Powers signed treaties containing similar articles. This article, Article 231, became known as the "War Guilt" clause.

The century of humiliation (simplified Chinese: 百年国耻; traditional Chinese: 百年國恥; pinyin: bǎinián guóchǐ) was a period in Chinese history beginning with the First Opium War (1839–1842), and ending in 1945 with China (then the Republic of China) emerging out of the Second World War as one of the Big Four and established as a permanent member of the United Nations Security Council, or alternatively, ending in 1949 with the founding of the People's Republic of China. The century-long period is typified by the decline, defeat and political fragmentation of the Qing dynasty and the subsequent Republic of China, which led to demoralizing foreign intervention, annexation and subjugation of China by Western powers, Russia, and Japan.

The characterization of the period as a "humiliation" arose with an atmosphere of Chinese nationalism following China's defeat in the First Sino-Japanese War of 1894–1895 and the subsequent events including the scramble for concessions in the late 1890s. Since then the idea of national humiliation became a focus of discussions among many Chinese writers and scholars, although they differed somewhat in their understandings of national humiliation; ordinary scholars and constitutionalists also had different understanding of their home country from the anti-Qing revolutionaries in the late Qing period. The idea of national humiliation was also mentioned in late Qing textbooks.

Anton Alexander von Werner (9 May 1843 – 4 January 1915) was a German painter and illustrator, best known for his depictions of the Franco-Prussian War and the Unification of Germany, typical of the Naturalist style. Member of the Akademie der Künste from 1874, Werner was a favourite of all the three German Emperors, William I, Frederick III, and Wilhelm II.

Wilhelm I (William I; William Frederick Louis; German: Wilhelm Friedrich Ludwig; 22 March 1797 – 9 March 1888) was King of Prussia from 1861 and German Emperor from 1871 until his death in 1888. A member of the House of Hohenzollern, he was the first head of state of a united Germany. He was regent of Prussia from 1858 to 1861 for his elder brother, King Frederick William IV. During the reign of his grandson Wilhelm II, he was known as Emperor Wilhelm the Great (German: Kaiser Wilhelm der Große).

The second son of Prince Frederick William and Louise of Mecklenburg-Strelitz, Wilhelm was not expected to ascend to the throne. His grandfather, King Frederick William II died the year he was born, and his father was crowned Frederick William III. Wilhelm fought with distinction during the War of the Sixth Coalition, and afterwards became a prominent figure within the Prussian Army. In 1840, his childless elder brother became King of Prussia, making him heir presumptive. Wilhelm played a major role in crushing the Revolutions of 1848 in Germany, although he was briefly forced into exile in England. Frederick William IV suffered a stroke in 1857 and was left incapacitated, and Wilhelm was formally named Prince Regent a year later. In 1861, Wilhelm ascended to the Prussian throne on his elder brother's death.

The Imperial German Navy or the Kaiserliche Marine (Imperial Navy) was the navy of the German Empire, which existed between 1871 and 1919. It grew out of the small Prussian Navy (from 1867 the North German Federal Navy), which was mainly for coast defence. Kaiser Wilhelm II greatly expanded the navy. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a naval arms race with Britain, as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy.

The German surface navy proved ineffective during the First World War; its only major engagement, the Battle of Jutland, was a draw, but it kept the surface fleet largely in port for the rest of the war. The submarine fleet was greatly expanded and threatened the British supply system during the U-boat campaign. As part of the Armistice, the Imperial Navy's main ships were ordered to be turned over to the Allies but they were instead scuttled by their own crews. All ships of the Imperial Navy bore the prefix SMS, for Seiner Majestät Schiff (His Majesty's Ship).
