The Netherlands, Great Britain, and France sign the Triple Alliance

The Triple Alliance of 1717 was a significant diplomatic pact between the Netherlands, Great Britain, and France, established to maintain the balance of power in Europe following the turbulence of the War of the Spanish Succession (1701–1714). This alliance was primarily directed against the expansionist ambitions of Spain under Philip V, particularly concerning Spanish territorial claims in Italy. The three nations, though historically adversaries at various points, came together to counter Spain’s attempts to upset the precarious European equilibrium by reclaiming territories like Sardinia and Sicily. This coalition sought to preserve the provisions of the Treaty of Utrecht (1713) by ensuring that no single power could dominate European politics. While the Triple Alliance succeeded in restraining Spain temporarily, it also demonstrated the pragmatism of 18th-century diplomacy, where erstwhile rivals collaborated to serve mutual interests.
