Cuius Regio explores the operational military aspects of this pivotal period in European history and focuses on the maneuvers and battles that shook Europe for three decades.
The Thirty Years War unfolded in four main phases: the Bohemian Revolt from 1618 to 1625, the Danish intervention from 1625 to 1630, the Swedish intervention from 1630 to 1635, and the French intervention from 1635 to 1648. It concluded with the Peace of Westphalia in 1648, which finally established a new status quo in Europe, the concept of the sovereignty of states, and shifted the focus of continental politics from southern Europe to the northern states.
