Germany's Blank Cheque to Austria-Hungary

Germany’s offer of unconditional support to its Austro-Hungarian ally in July 1914 remains one of the most controversial decisions in modern history. Historians have interpreted the blank cheque in several, often contradictory, ways – either as a German attempt to escalate a regional crisis into a wider European war or as a move to localise war in the Balkans. Most historians agree that the blank cheque marked a victory for the war party in Vienna.
