Kingdom of Lombardy–Venetia
The Kingdom of Lombardy–Venetia, commonly called the Lombardo-Venetian Kingdom, was a constituent land (crown land) of the Austrian Empire from 1815 to 1866. It was created in 1815 by resolution of the Congress of Vienna in recognition of the Austrian House of Habsburg-Lorraine's rights to the former Duchy of Milan and the former Republic of Venice after the Napoleonic Kingdom of Italy, proclaimed in 1805, had collapsed.
