Archduke Franz Ferdinand was heir to the throne of Austria. On 28 June 1914, he and his wife were shot dead by Serb nationalist, Gavrilo Princip. With German support, Austria attempted to use the assassinations as a chance to crush Serbia. When Russia prepared to defend Serbia, Germany too became involved in the conflict. In turn, the alliance with Russia brought France into the conflict. Germany declared war on them both on 1 August 1914.
