Final answer:
The 'balance of power' concept was to prevent any one nation from dominating others in Europe, especially in the wake of the Napoleonic Wars, and it was central to the diplomatic efforts at the Congress of Vienna.
Step-by-step explanation:
The idea behind the "balance of power" concept in European diplomacy during the French Revolution was to prevent any one country from becoming too dominant and thereby threatening the others. This balance of power approach arose in response to the Napoleonic Wars, as European leaders, such as the Austrian foreign minister Klemens von Metternich, aimed to contain France and establish an equilibrium that prevents one nation from dominating others. The restoration of balance in Europe involved redrawing political boundaries, creating stronger states around France to check its power, and ensuring an equitable distribution of military and political power among the European powers.
During the Congress of Vienna in 1814-1815, the Quadruple Alliance, including Metternich, aimed to maintain European peace and stability by restoring monarchies and preventing the spread of democratic principles that arose from the revolution. The Congress System, or the Concert of Europe, emerged as a conservative international political network intended to suppress future revolutionary movements and maintain a status quo that would ensure lasting conservative order.
