Facts and Events
Giuseppe Gonzaga (March 20, 1690 – August 16, 1746) was the last Duke of Guastalla.
He was the second son of Vincenzo Gonzaga, Duke of Guastalla and Maria Vittoria Gonzaga, and was mentally handicapped.
Giuseppe would probably never have married, but when he became Duke a marriage was arranged in 1731 with the sixteen year-old Eleonore von Holstein (1715–1760), daughter of Duke Leopold of Schleswig-Holstein-Sonderburg-Wiesenburg. The marriage remained childless.
During the War of Polish Succession the Duchy was occupied by the French for four years, between 1734 and 1738.
