Cause → Event → Consequence
France, under Louis XIV, launched the War of Devolution in May 1667, occupying the Spanish Netherlands and Franche-Comté. This alarmed England and the Dutch Republic, who had previously been at war with each other, and prompted them to seek a common diplomatic front to check French expansion in the Low Countries.
In May 1668, England, the Dutch Republic, and Sweden concluded the Triple Alliance, comprising a defensive pact, an undertaking to compel a Franco-Spanish peace, and secret clauses providing for mediation and, if necessary, military enforcement. Spain and Emperor Leopold, though not signatories, were closely involved in shaping the negotiations.
The alliance was brief; both Sweden and England sided with France when the Franco-Dutch War began in 1672. Nevertheless, it established a precedent for Anglo-Dutch cooperation against France and is considered a direct forerunner of the Grand Alliance that fought the Nine Years' War (1688–1697) and the War of the Spanish Succession (1701–1714).
Political Outcome
A short-lived defensive alliance that checked French expansion temporarily and prefigured broader anti-French coalitions later in the century.
France freely expanded into the Spanish Netherlands and Franche-Comté with limited coordinated opposition.
England and the Dutch Republic recognized France as a shared threat, laying groundwork for enduring anti-French coalition diplomacy.
