The "Concerto da Europa," or "Concert of Europe," refers to a diplomatic system established in the early 19th century among the major European powers. It aimed to maintain peace and stability following the upheaval of the Napoleonic Wars. Key participants included Austria, Britain, Prussia, Russia, and later France, who collaborated to manage international relations and prevent conflicts through regular meetings and agreements. This system was characterized by a balance of power, where no single nation would dominate Europe. The "Concerto da Europa" played a significant role in shaping European politics until the outbreak of World War I, when the complex alliances and rivalries ultimately led to widespread conflict.
