Treaty of Naples (1639)

Treaty of Naples was a political-military agreement between the Kingdom of Spain and the Kingdom of Poland, signed in Naples in late 1639. The Polish king Władysław IV agreed to raise an army of 17,000 men, which would consist of 12,000 cavalry and 5,000 infantry. Following transit across the imperial territory, the troops were to be employed under Spanish command in Flanders against the French. The Spanish king Felipe IV, apart from covering recruitment and maintenance cost, was to pay the Polish monarch 500,000 Neapolitan escudos. The Poles almost immediately demanded re-negotiation of the treaty, which resulted in another agreement concluded in 1641; the Spaniards were to pay more for an even smaller army. This treaty was not implemented either, and the Madrid court cancelled the deal in early 1642. The treaty remains the only bilateral Spanish-Polish military alliance agreement ever concluded between the two countries.
