A gunpowder revolution occurred in the 17th century and changed social and political structures.

Test against mainstream historiography of gunpowder warfare and the 'Military Revolution' (Roberts, Parker, etc.). True: historians widely describe a gunpowder-driven military revolution that substantially falls in the 17th century (e.g. Roberts's 1560–1660) and credit it with major social and political change (e.g. growth of standing armies, centralised states, fiscal-military states, decline of feudal or noble military power). Mostly true: the transformation is real and gunpowder-driven, but is usually dated as spanning roughly the 15th to 17th centuries rather than just the 17th, which is a minor dating slip. Mixed: the social and political effects are well supported, but the timing is mainly placed outside the 17th century, or historians are deeply divided over whether there was a 'revolution' at all. Mostly false: gunpowder's main transformative effects are firmly dated well before the 17th century, or its causal role in social and political change is largely rejected. False: there is no historical basis for gunpowder bringing about meaningful social or political change.

   “The Military Revolution is the theory that a series of radical changes in military strategy and tactics during the 16th and 17th centuries resulted in major lasting changes in governments and society.”

2. E2 Military Revolution Wikipedia · 22 September 2004 Own record

   “The concept of a military revolution during this time has received a mixed reception among historians.”

3. E3 Is there still life in the Military Revolution? Davis Kedrosky (Substack blog) · 6 September 2023

   “Army sizes did expand as a result of interstate warfare in (but not exclusively in) the 'Roberts century' 1560-1660, and this growth was a primary impetus for the development of the fiscal state”

4. E4 Periodizing the Military Revolution Debate Mil-Historicus (blog) · 4 November 2014

   “Simon Adams and David Parrott lead those who disagree with Roberts’ thesis of the military revolution as a cause for the increased centralization of European governments.”

E1 describes the Military Revolution as radical military change in the 16th and 17th centuries producing lasting changes in government and society. E3 finds that army growth from interstate warfare in Roberts's 1560–1660 period was a primary impetus for the fiscal state. E2 and E4 show the concept has a mixed reception, with some historians rejecting the causal link to state centralisation. The core claim has support, but the transformation is dated across the 16th and 17th centuries rather than the 17th alone, and the thesis is contested.
