Germany got unified and rose to be a highly industrialized nation rather late (second half of the 19th century). But the unity of Germany under the leadership of Prussia came after defeating France in the Franco-Prussian War of 1870-1871, a conflict that fed many of the grievances that led to WWI and WWI.
