List of Governors of the Duchy of Milan

The Governor of Milan ruled the Duchy of Milan as a representative of the King of Spain (1535–1706) and the Archduke of Austria (1706–1796) and (1799–1800). The first governor was appointed after the death of the last duke of the House of Sforza, Francesco II.

Milan fell to the Austrian army on September 26, 1706 during the War of the Spanish Succession. The Austrian rule was confirmed by the Treaty of Rastatt.

The Austrians abandoned Milan after the Battle of Marengo and the duchy was incorporated again in the Cisalpine Republic, which became the Italian Republic in 1802 and the Kingdom of Italy in 1805. In 1814 the Austrians retook Milan and, joined to the former Republic of Venice, it was formed into a new kingdom, the Kingdom of Lombardy-Venetia, ruled by Austrian-appointed viceroys.
