Gavrilo Princip shot and killed Archduke Franz Ferdinand, and his wife Sophie, on this day in 1914. Archduke Franz Ferdinand was the heir to the Austro-Hungarian throne and Gavirilo Princip was a Bosnian Serb nationalist. The assassination triggered a series of diplomatic crises and ultimatums between Austria-Hungary and Serbia.

Unfortunately the European powers had formed complex and interconnected alliances, with the two main blocs being the Triple Entente (France, Russia, and Britain) and the Central Powers (Germany, Austria-Hungary, and Italy). The alliances created a delicate balance of power, but also meant that a localized conflict could quickly escalate into a full-scale war.

Each European power exhibited a strong sense of nationalism and sought to expand their empires and influence. This led to increased tensions and rivalries between countries. The powers had also developed intricate military plans and strategies, known as war plans, which required quick mobilization and pre-emptive strikes.

Despite efforts to resolve the crisis through diplomatic means, the failure of negotiations and the rigid alliance system meant that countries were bound to support their allies in case of war. This led to a rapid escalation of the conflict into the First World War. Sadly this hasn’t been known as the war to end all wars since 1939. Wars in Korea, Vietnam and now Ukraine suggest that despite the horror of war they just keep coming.

Dennis Wheatley wrote a brilliant book about the build up to the assassination of Archduke Franz Ferdinand. It’s called The Second Seal. I’ve posted in Reader’s Club about how his books influence my writing style. The way that his invented characters interact with real characters and events has been my inspiration for the Sir Anthony Standen Adventures. The main difference is that Sir Anthony Standen was a real character, and the brother of my 10th great-grandfather.
