メキシコ皇帝
Apart from the core Habsburg dominions, including the triple crowns of Austria, Hungary and Bohemia, several junior branches of the House of Habsburg-Lorraine reigned in the Italian duchies of Tuscany (until 1860), Parma (until 1847) and Modena (until 1859). Another member of the house, Archduke Maximilian of Austria, was Emperor of Mexico (1863–67).
