Final answer:
The claim that Germany adopted the Prussian anthem using the tune of "God Save the Queen" upon unification in 1871 is False; a different anthem was established.
Step-by-step explanation:
The statement that Germany adopted the Prussian national anthem, which used the same tune as "God Save the Queen" when it was unified in 1871, is False. When Germany unified in 1871, the new nation did not adopt the Prussian anthem; instead, the German Empire established its own national anthem 'Das Lied der Deutschen' (The Song of the Germans), with a melody composed by Joseph Haydn. This tune was different from that used by "God Save the Queen". The unification of Germany was a significant historical mark led by the conservative Prussian statesman Otto von Bismarck. It resulted in a powerful new country that challenged the established balance of power in Europe, leading to shifting alliances and ultimately contributing to the onset of World War I.
