メキシコ皇帝
In December 1861, Emperor Napoleon III invaded Mexico on a pretext that Mexico had refused to pay its foreign debt, though in retrospect, Emperor Napoleon III wanted to expand his empire in Latin-America and this became known as the Second French intervention in Mexico. After a successful French invasion of Mexico, Napoléon III installed his Austrian cousin, Maximilian I of Mexico of the House of Habsburg, as Emperor of Mexico in 1864.
