The Order of Saint Stephen (Official: Sacro Militare Ordine di Santo Stefano Papa e Martire, "Holy Military Order of St. Stephen Pope and Martyr") is a Tuscan dynastic-military order founded in 1561. The order was created by Cosimo I de' Medici, first Grand Duke of Tuscany. The last member of the Medici dynasty to be a leader of the order was Gian Gastone de Medici in 1737. The order was permanently abolished in 1859 by the annexation of Tuscany to the Kingdom of Sardinia. The former Kingdom of Italy and the current Italian Republic also did not recognize the order as a legal entity but tolerates it as a private body.
