Which states did Bismarck engineer wars against, and in what approximate period?

• A. Denmark, Austria, and France from 1862 to 1890.
• B. Russia, Prussia, and Britain from 1840 to 1860.
• C. Sweden and Norway from 1800 to 1810.
• D. Poland and Hungary from 1900 to 1910.

Answer: (A)

The idea being tested is how Bismarck used a deliberate series of wars to achieve German unification. He steered conflicts with Denmark, Austria, and France, in that order, to secure territorial gains, exclude Austria from a unified Germany, and rally the southern German states to join the empire. The Danish War (1864) opened Schleswig-Holstein, the Austro-Prussian War (1866) set up a Prussian-led North German Confederation and pushed Austria out of central German affairs, and the Franco-Prussian War (1870–71) completed unification by bringing the southern states into the new German Empire. The timeframe around these campaigns is best captured by a rough window from the early 1860s to the early 1870s, which fits the provided option. The other pairings involve different powers or eras that don’t match the actual sequence of Bismarck’s unification wars.
