The correct answer is option A) "Frederick II took Silesia". In the Austro-Prussian War or Seven Weeks' War, the leader of Prussia King Frederick the Great resulted victorious over Austria. This changed the map of Europe because the kingdom of Prussia gained control of extensive new lands in Silesia, including highly industrialized and densely populated areas.
Even though the revolutions did not succeed, the forces of liberalism and nationalism triumphed after 1850 because of the ideas of several individuals and artists such as Karl Marx and Gustave Flaubert. Another reason is that the people were made aware of the corrupt and deceitful actions of Napoleon III.<span />
