About Charlotte of Belgium
Charlotte of Belgium (7 June 1840 – 19 January 1927), also known by the Spanish version of her name, Carlota of Mexico, 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 numerous 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. On her own initiative, Charlotte decided to go personally to Europe in order to attempt a final approach to Paris and the Vatican. She landed in France in August 1866, but suffered the successive refusals of both Napoleon III and Pope Pius IX. In Rome, the failure of her mission appeared to compromise her mental health to the point that an alienist doctor advocated the confinement of Charlotte in Miramare Castle. It was during her stay under house arrest that Maximilian was deposed and executed under Benito Juárez in June 1867. Unaware that she was a widow, Charlotte was brought back to Belgium and confined successively in the Pavilion of Tervuren (in 1867 and again during 1869–1879), the Palace of Laeken (during 1867–1869) and finally at Bouchout Castle in Meise (from 1879), where she remained for the next 48 years in a deleterious mental state, giving rise to much speculation ever since, before dying in 1927 aged 86. Her first name pays homage to the late Princess Charlotte of Wales, her father's first wife. As the wife of Archduke Maximilian of Austria, Viceroy of Lombardy–Venetia and later Emperor of Mexico, she became Archduchess of Austria and Empress of Mexico.
