Evaluate the responsibility of William Kaiser for First World War.

Responsibility of Kaiser Wilhelm II for the Outbreak of World War I (1914):

German Emperor Kaiser Wilhelm II (1888–1918) bore cardinal personal responsibility for plunging Europe into the catastrophic First World War due to his aggressive militaristic policies:

• 1. Abandonment of Bismarck's Cautious Realpolitik: Dismissed Chancellor Otto von Bismarck in 1890, ended the Reinsurance Treaty with Russia, driving Russia directly into the Franco-Russian Alliance.
• 2. Aggressive 'Weltpolitik' (World Imperialism): Pursued aggressive naval expansion (building dreadnought battleships to challenge the British Royal Navy) and demanded Germany's "Place in the Sun", triggering an intense European arms race.
• 3. Precipitating International Crises: Provoked the First Moroccan Crisis (Tangier, 1905) and Second Moroccan Crisis (Agadir, 1911), inflaming British and French hostility.
• 4. The "Blank Cheque" to Austria-Hungary (July 1914): Following the assassination of Archduke Franz Ferdinand at Sarajevo, Wilhelm II gave unconditional military support (Blank Cheque) to Austria to invade Serbia, escalating a local Balkan dispute into a global world war.
