The stately quadrille is the name given to set of constantly shifting alliances between the great powers of Europe during the 18th century. The ultimate objective was to maintain the balance of power in Europe to stop any one alliance or country becoming too strong. It takes its name from the quadrille, a dance in which the participants constantly swap partners.
The quadrille was a popular dance of the 18th century. Because of its similarity to the way in which Great Powers swapped partners, the term was swiftly applied to describe it.
European balance of power
The European balance of power is a tenet in international relations that no single power should be allowed to achieve hegemony over a substantial part of Europe. During much of the Modern Age, the balance was achieved by having a small number of ever-changing alliances contending for power, which culminated in the World Wars of the early 20th century. By 1945, European-led global dominance and rivalry had ended and the doctrine of European balance of power was replaced by a worldwide balance of power involving the United States and the Soviet Union as the modern superpowers.
