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.
He made his stepson, Eugène de Beauharnais, Viceroy on 5 June 1805, and later his heir presumptive to the Italian crown.
The Agreement of Schiarino-Rizzino [it] was agreed on 16 April outside Mantua, which enabled Eugène to keep control of his territory.
Eugène signed the Convention of Mantua on 24 April, allowing the Austrian commander, Bellegarde, to cross the River Minco and occupy Milan, and northern Italy returned to Austrian rule on 27 April.
Austrian control of Lombardy and Venetia was confirmed by the Congress of Vienna, and the territories were joined as the Kingdom of Lombardy–Venetia on 7 April 1815.
