Final answer:
The question seems to confuse Frederick William II with Frederick the Great (Frederick II) and also refers to events related to the unification of Germany, involving Wilhelm I and Otto von Bismarck. Frederick the Great was located in Prussia, while the unification events took place in various locations including the Palace of Versailles.
Step-by-step explanation:
The question refers to a historical figure known as Frederick William II, often confused with Frederick the Great (Frederick II). It is important to note that Frederick the Great reigned as the King of Prussia from 1740 until 1786, while Frederick William II was his nephew and successor, reigning from 1786 until 1797. However, if the question intimates the unification of Germany and related events, this pertains to a later period, particularly involving Wilhelm I and Otto von Bismarck.
Frederick the Great's location, in a broad historical context, was in Prussia, which was a German kingdom that included parts of what is now Germany, Poland, and Lithuania. He is associated with the Sanssouci Palace in Potsdam, near Berlin, where he resided and is buried. In contrast, Wilhelm I was proclaimed Emperor in a ceremony at the Palace of Versailles after the Franco-Prussian War, marking a significant moment in German history. The unification of Germany was a process influenced by the efforts of the Zollverein, the Frankfurt Assembly, and the policies of Prime Minister Otto von Bismarck.
