Military History

Understanding how the military instrument of power has been used is a core part of RUSI’s mission and legacy with profound lessons and implications for today’s decisions and tomorrow’s policies.

A core part of RUSI’s work and mission is its appreciation and acknowledgement of military history as an integral element of our values, the Institute’s own history, and our legacy. In establishing RUSI, the founders explicitly accepted and acknowledged how an understanding and analysis of military history was essential in shaping contemporary policy and decision-making. This is as true today, as it was in 1831.

This topic page draws together journal articles, commentary and seminars on warfare and the armed forces from a historical perspective. We also showcase resources from the RUSI Library of Military History and recent winners of the Duke of Wellington Medal for Military History and Trench Gascoigne Essay Prize. The themes, subjects and spread of analysis that we cover under the umbrella of military history is unavoidably and unapologetically wide.
