By the Numbers
Cause → Event → Consequence
The War of the Spanish Succession placed a branch of the French House of Bourbon on the Spanish throne. Post-war settlements required that the two Bourbon crowns remain separate, yet the shared dynastic identity created conditions for structured cooperation between the two kingdoms.
France and Spain concluded three successive treaties known collectively as the Pacte de Famille, signed in 1733, 1743, and 1761. Each agreement established a formal military and diplomatic alliance between the Bourbon monarchies, obligating mutual support without merging the two thrones.
The pacts enabled coordinated Franco-Spanish military action across multiple eighteenth-century conflicts. The alliance persisted for decades before being dissolved by the upheaval of the French Revolutionary Wars, which overthrew the French Bourbon monarchy and ended the dynastic basis for the compacts.
Political Outcome
Three successive treaties formalized a Bourbon family alliance between France and Spain, providing for mutual military and diplomatic cooperation until the French Revolutionary Wars broke the arrangement.
