History of Friedrich II of Prussia — Volume 21

This volume chronicles the later decades of Frederick II's reign, detailing postwar reconstruction, fiscal experiments including a Helvetius-designed excise and the popular discontent it provoked, cultural encounters with figures such as D'Alembert and Voltaire, architectural projects like the Neue Palais at Sanssouci, and diplomatic crises surrounding Poland's anarchy and partition, Russo-Turkish conflicts, and interviews with Emperor Joseph. It also treats military, legal, and domestic episodes—reviews, the Bavarian War, the Miller Arnold lawsuit—and blends narrative passages with essays and miscellanies that illuminate administrative reforms, foreign-policy maneuvers, and the monarch's character in his later life.
