War of Roussillon, also called War of the Pyrenees or War of the Convention, (1793-1795). Conflict between the Spain of Charles IV and the First French Republic. Neither France nor Spain could continue the war, the treasury situation did not allow it.

Domingo Iriarte and Barthelemy sign the Peace in Basel on 22 July 1795. Engraving by Algarra. Historia del Levantamiento, guerra y revolucion de Espana by the Conde de Toreno. Madrid, 1851.
