After Emperor Frederick III died during the "Year of the Three Emperors," Wilhelm II became German Emperor and King of Prussia, beginning a reign marked by more personal, interventionist monarchy.
Wilhelm II forced the resignation of Otto von Bismarck, ending the founding chancellor’s dominance and opening a new phase of policymaking in which the emperor sought greater direct influence over government.
Germany and Britain agreed on spheres of influence in East Africa; Britain ceded Heligoland to Germany. The deal mattered for imperial policy and naval strategy in the North Sea.
Wilhelm II sent a congratulatory telegram to Transvaal President Paul Kruger after the Jameson Raid failed. The message caused public outrage in Britain and worsened diplomatic relations.
The 1898 Navy Law (associated with Tirpitz’s program) authorized a major fleet expansion, anchoring Wilhelm II’s Weltpolitik and intensifying strategic rivalry—especially with Britain.
The 1900 Navy Law substantially increased planned battleship and cruiser strength, accelerating naval construction and deepening the political-economic commitment to a battle fleet.
At Bremerhaven, Wilhelm II delivered the "Hun Speech" to troops departing for China during the Boxer Rebellion. The speech became emblematic of militarized imperial rhetoric and attracted international attention.
Chief of staff Alfred von Schlieffen first proposed the operational concept later known as the Schlieffen Plan, shaping German strategic planning for a two-front war and becoming central to debates about civil-military decision-making in 1914.
Wilhelm II’s visit and speech in Tangier challenged French influence in Morocco and tested the Entente Cordiale. The episode helped harden diplomatic blocs that later confronted each other in World War I.
Wilhelm II and Nicholas II signed a secret mutual-defense treaty at Björkö without full ministerial coordination. The agreement was quickly repudiated and never took effect, illustrating Wilhelm’s personal diplomacy risks.
Publication of Wilhelm II’s interview in The Daily Telegraph caused a major political scandal in Germany and harmed the emperor’s reputation, intensifying criticism of his impulsive public diplomacy.
After Bülow’s resignation, Theobald von Bethmann Hollweg became chancellor under Wilhelm II. His tenure encompassed escalating international crises and the opening years of World War I.
Germany sent the gunboat Panther to Agadir, intensifying confrontation with France and alarming Britain. The crisis further strained diplomacy and contributed to the prewar atmosphere in European politics.
Chancellor Bethmann Hollweg authorized a memorandum (drafted by Kurt Riezler) setting out expansive German war aims early in World War I—an important document for understanding imperial policy debates during the conflict.
The British liner RMS Lusitania was torpedoed by a German U-boat, killing nearly 1,200 people and inflaming international opinion—especially in the United States—adding pressure on German imperial decision-making over submarine warfare.
Although abdication was announced in Germany on 1918-11-09, Wilhelm II formally affirmed in writing his renunciation of the Prussian and imperial thrones while in exile at Amerongen, ending Hohenzollern rule.
