El Tratado de Nápoles. El encierro del príncipe JuanCasimiro y la leva de polacos de Medina de las Torres (1638-1642)

Abstract

Throughout the seventeenth century, the Vasa of Poland and the Habsburg family established a series of contacts which would link to the Catholic Monarchy with the events in Eastern Europe. This article addresses a specific event of these relationships: the closure by the French of Prince Casimir on his way to Spain, and subse-quent negotiations between his half-brother, King Ladislaus IV, and the viceroy of Naples, the Duke of Medina de las Torres, to raise an army of punishment to free the prince. In this negotiation between Naples, Madrid, Vienna and Warsaw, the catholic king diplomacy interacted with leading personalities of the Polish court.
