Kingdom of Lombardy–Venetia in the context of "Kingdom of Italy (Napoleonic)"

Veneto, officially the Region of Veneto, is one of the 20 regions of Italy, located in the north-east of the country. It is the 4th most populous region in Italy, with a population of 4,851,851 as of 2025. Venice is the region's capital while Verona is the largest city.

Veneto was part of the Roman Empire until the 5th century AD. Later, after a feudal period, it was part of the Republic of Venice until 1797. Venice ruled for centuries over one of the largest and richest maritime republics and trade empires in the world. After the Napoleonic Wars and the Congress of Vienna, the former Republic was combined with Lombardy and re-annexed to the Austrian Empire as the Kingdom of Lombardy–Venetia, until that was merged with the Kingdom of Italy in 1866, as a result of the Third Italian War of Independence and of a plebiscite.

Maximilian I (Spanish: Fernando Maximiliano José María de Habsburgo-Lorena; German: Ferdinand Maximilian Josef Maria von Habsburg-Lothringen; 6 July 1832 – 19 June 1867) was an Austrian archduke who became emperor of the Second Mexican Empire from 10 April 1864 until his execution by the Mexican Republic on 19 June 1867.

A member of the House of Habsburg-Lorraine, Maximilian was the younger brother of Emperor Franz Joseph I of Austria. Before becoming Emperor of Mexico, he was commander-in-chief of the small Imperial Austrian Navy and briefly the Austrian viceroy of Lombardy–Venetia, but was removed by the emperor. Two years before his dismissal, he briefly met with French emperor Napoleon III in Paris, where he was approached by conservative Mexican monarchists seeking a European royal to rule Mexico. Initially Maximilian was not interested, but following his dismissal as viceroy, the Mexican monarchists' plan was far more appealing to him.

The Third Italian War of Independence (Italian: Terza guerra d'indipendenza italiana) was a war between the Kingdom of Italy and the Austrian Empire fought between June and August 1866. The conflict paralleled the Austro-Prussian War and resulted in Austria giving the region of Venetia (present-day Veneto, Friuli and the city of Mantua, the last remnant of the Quadrilatero) to the Second French Empire (acting as intermediary in negotiations), which formally gave it to Italy. Italy's acquisition of this wealthy and populous territory, annexed with a plebiscite, represented a major step in the Unification of Italy.

Charlotte of Mexico (French: Marie Charlotte Amélie Augustine Victoire Clémentine Léopoldine; Spanish: María Carlota Amelia Augusta Victoria Clementina Leopoldina; 7 June 1840 – 19 January 1927), known by the Spanish version of her name, Carlota, was by birth a princess of Belgium and member of the House of Wettin in the branch of Saxe-Coburg and Gotha (as such, she was also styled Princess of Saxe-Coburg and Gotha and Duchess in Saxony). As the wife of Archduke Maximilian of Austria, Viceroy of Lombardy–Venetia and later Emperor of Mexico, she became Archduchess of Austria (in 1857) and Empress of Mexico (in 1864). She was the daughter, granddaughter, sister, sister in-law, cousin and wife of reigning or deposed sovereigns throughout Europe and Mexico.

From the beginning of her marriage, she feuded with Empress Elisabeth in Vienna, and was glad when her husband was posted to Italy as Viceroy of Lombardy–Venetia. At this time, he was selected by the Emperor Napoleon III as a figurehead for his proposed French empire in Mexico, and Charlotte overcame her husband's doubts about the plan. Maximilian and Charlotte duly arrived in Mexico City in 1864, but their reign lasted little more than three years. She assisted her husband, who let her rule as regent during his absences from Mexico City, for which reason she is considered the first woman to rule in the Americas. When Napoleon III ordered the withdrawal of French military aid intended to support Maximilian, the situation of the Mexican imperial couple became untenable.

Milan was ruled by dukes from the 14th century to 1814, after which it was incorporated into the Kingdom of Lombardy–Venetia by the Congress of Vienna.

The Austro-Prussian War (German: Preußisch-Österreichischer Krieg) was fought in 1866 between the Austrian Empire and the Kingdom of Prussia, with each also being aided by various allies within the German Confederation. Prussia had also allied with the Kingdom of Italy, linking this conflict to the Third Independence War of Italian unification. The Austro-Prussian War was part of the wider rivalry between Austria and Prussia, and resulted in Prussian dominance over the German states, having confirmed Prussia's superior military organization and technology compared to Austria at the time.

The major result of the war was a shift in power among the German states away from Austrian and towards Prussian hegemony. It resulted in the abolition of the German Confederation and its partial replacement by the unification of all of the northern German states in the North German Confederation that excluded Austria and the other southern German states, a Kleindeutsches Reich. The war also resulted in the Italian annexations of the Austrian realm of Venetia.
