On War (Vom Kriege‪)‬

Vom Kriege (On War) is a book on war and military strategy by
Prussian general Carl von Clausewitz, written mostly after the Napoleonic wars,
between 1816 and 1830, and published posthumously by his wife in 1832. It has
been translated into English several times as On War. On
War is actually an unfinished work; Clausewitz had set about revising his
accumulated manuscripts in 1827, but did not live to finish the task. His wife
eventually compiled all the work and the final two chapters Clausewitz never
finished.

On War is one of the first books on modern military strategy. This is
mainly due to Clausewitz' integration of politics and social and economic issues
as some of the most important factors in deciding the outcomes of a war. It is
one of the most important treatises on strategy ever written, and is prescribed
at various military academies to this day.
