Final Answer:
The Congress of Vienna D) The monarchies of Europe prior to the French Revolution were restored.
Step-by-step explanation:
The Congress of Vienna, held from 1814 to 1815, aimed to restore stability and order in Europe after the upheavals caused by the Napoleonic Wars. The correct option is D, as the primary accomplishment of the Congress of Vienna was the restoration of the monarchies that existed in Europe before the French Revolution. This was done in an effort to roll back the revolutionary changes brought about by Napoleon and to reestablish the balance of power among European nations.
The Congress of Vienna sought to restore the traditional monarchies that had been overthrown or disrupted during the French Revolution and the Napoleonic era. The major European powers, including Austria, Prussia, Russia, and the United Kingdom, were instrumental in this restoration. The idea was to reinstate legitimate monarchs to their thrones to maintain stability and prevent further revolutionary upheavals. This decision had a significant impact on the political landscape of Europe in the early 19th century.
The other options (A, B, and C) are not accurate. Napoleon was not installed as the leader of France at the Congress of Vienna (Option A). Also, the shift from absolute monarchies to limited monarchies did not occur universally across Europe (Option B). Additionally, Germany was not established as a limited monarchy at the Congress of Vienna (Option C).
In summary, the Congress of Vienna achieved the restoration of pre-revolutionary monarchies in Europe, making Option D the correct answer.
