I want to know the answer to the following question:
How much of the land did Prussia control?
All the background I'm provided with is that "The Confederation was dissolved after the Austro-Prussian War and replaced by a North German Federation under Prussian hegemony; this war left Prussia dominant in Germany, and German nationalism would compel the remaining independent states to ally with Prussia in the Franco-Prussian War of 1870–71, and then to accede to the crowning of King Wilhelm of Prussia as German Emperor.". Is that enough to answer the question?
