Convention of Mantua: Kingdom of Italy returned to Austrian rule

Background. The Napoleonic Kingdom of Italy was a client state of the French Empire, established in 1805 with Napoleon as King and Eugène de Beauharnais as Viceroy. Following Napoleon's defeat by the Sixth Coalition and his abdication in April 1814, Eugène attempted to preserve his position but faced military pressure from Austrian forces. The Convention of Mantua formalized the transition of authority from the Napoleonic administration to provisional Austrian control.

Terms and Execution. Signed on 24 April 1814, the Convention permitted the Austrian commander Bellegarde to cross the River Mincio and occupy Milan. Consequently, northern Italy returned to Austrian rule on 27 April. The agreement facilitated the disbandment of specific Italian military divisions, including those of Severoli and Lechi, following the signing. This provisional arrangement preceded the formal annexation by the Austrian Empire later in 1814.

Immediate Aftermath. Following the Convention, Count Heinrich von Bellegarde assumed powers in Lombardy on 25 May. The Treaty of Paris was signed on 30 May, leading to the annexation of the remaining kingdom territories by the Austrian Empire as the Kingdom of Lombardy–Venetia. Mantua, having returned to Austria in 1814, became a fortress city within this new administrative structure.
