 Clausewitz did not focus solely on wars between countries with well-defined armies.The era of the French Revolution and Napoleon was full of revolutions, rebellions, and violence by "non-state actors", such as the wars in the French Vendée and in Spain.Clausewitz wrote a series of “Lectures on Small War” and studied the rebellion in the Vendée (1793–1796) and the Tyrolean uprising of 1809.
