Fra' Jean Parisot de Valette (4 February 1495, Parisot, Rouergue - 21 August 1568, Malta) was a French nobleman and 49th Grand Master of the Order of Malta, from 1557 to 1568. As a Knight Hospitaller, joining the order in the Langue de Provence, he fought with distinction against the Turks at Rhodes. As Grand Master, Valette became the Order's hero and most illustrious leader, commanding the resistance against the Ottomans at the Great Siege of Malta in 1565, widely regarded as one of the greatest sieges of all time. He became Grand Master of the Knights Hospitaller on 21 August 1557.
