In 1866, the Prussian economy was rapidly growing, partly as a result of the German customs union, the {{lang|de|[[Zollverein]]}}, which gave Prussia an advantage in the war. Prussia could equip its armies with [[breech-loading rifles]] and later with new [[Krupp]] breech-loading [[artillery]] but the Austrian economy was suffering from the effects of the [[Hungarian Revolution of 1848]] and the [[Second Italian War of Independence]], so the state was heavily in debt. Historian [[Christopher Clark]] wrote that there is little to suggest that Prussia had an overwhelming economic and industrial advantage over Austria and wrote that a larger portion of the Prussian population was engaged in agriculture than in the Austrian population and that Austrian industry could produce the most sophisticated weapons in the war (rifled artillery). The Austro-Prussian War ended quickly and was fought mainly with existing weapons and munitions, which reduced the influence of economic and industrial power relative to politics and military culture.<ref>{{Cite book |last=Clark |first=Christopher |author-link=Christopher Clark |title=Iron Kingdom: The Rise and Downfall of Prussia |date=2008 |publisher=[[Harvard University Press]]}}{{page needed|date=August 2020}}</ref>
