The extinction of the Medici dynasty and the accession in 1737 of Francis Stephen, duke of Lorraine and husband of Maria Theresa of Austria, led to Tuscany's temporary inclusion in the territories of the Austrian crown. It became a secundogeniture of the Habsburg-Lorraine dynasty, who were deposed for the House of Bourbon-Parma in 1801. From 1801 to 1807 Florence was the capital of the Napoleonic client state Kingdom of Etruria. The Bourbon-Parma were deposed in December 1807 when Tuscany was annexed by France. Florence was the prefecture of the French département of Arno from 1808 to the fall of Napoleon in 1814. The Habsburg-Lorraine dynasty was restored on the throne of Tuscany at the Congress of Vienna but finally deposed in 1859. Tuscany became a region of the Kingdom of Italy in 1861.
