The Convention of Mantua was an agreement signed by Eugène de Beauharnais and Heinrich Graf von Bellegarde on 24 April 1814 that returned the territories of the Napoleonic Kingdom of Italy to provisional Austrian rule. Napoleon created himself King of Italy on 17 March 1805, and he was crowned with the Iron Crown of Lombardy in Milan on 26 May 1805. He made his stepson, Eugène de Beauharnais, Viceroy on 5 June 1805, and later his heir presumptive to the Italian crown.
