🔸 Carl von Clausewitz's wife, Marie, was instrumental in getting "On War" published after his death - she spent 23 years editing and organizing his manuscripts, ultimately publishing the work in 1832. 🔸 Author Hew Strachan spent over 30 years studying Clausewitz's works before writing this biography, establishing himself as one of the world's foremost authorities on the military theorist. 🔸 "On War" gained significant influence during World War I, nearly 100 years after its publication, when military leaders across Europe began seriously studying and applying its principles. 🔸 The famous quote "War is the continuation of politics by other means" was actually a simplified version of what Clausewitz wrote - his original text was more nuanced and complex. 🔸 Despite being considered one of the most important military treatises ever written, "On War" was left unfinished - only the first chapter was fully completed to Clausewitz's satisfaction before his death from cholera in 1831.
