The Barrier Treaties (Dutch: Barrièretraktaat/Barrièreverdrag; French: traités de la Barrière) were a series of agreements signed and ratified between 1709 and 1715 that created a buffer zone between the Dutch Republic and France by allowing the Dutch to occupy a number of fortresses in the Habsburg Netherlands, ruled by the Spanish or the Austrians. The treaties were cancelled by Austria in 1781.
