The country that was created by the Congress of Vienna to serve as a buffer between more powerful nations was the Kingdom of the United Netherlands.
The correct answer is the Kingdom of the United Netherlands. The Congress of Vienna, which took place from 1814 to 1815, was an international conference held following the defeat of Napoleon Bonaparte. Its main goal was to reestablish stability in Europe. As part of their efforts to maintain a balance of power, the representatives at the Congress created the Kingdom of the United Netherlands. This new country was intended to serve as a buffer between the more powerful nations of France and Prussia, thus preventing any one nation from becoming too dominant.
