The sure shield of the Monroe Doctrine, it seemed to him, was thrust aside for good, the Great Powers might meddle again in America, and the blessings of an adventurous monarchy be restored there. A pretext for interference was found in certain liberties taken with the property of foreigners by the Mexican president. A joint expedition of French, British, and Spanish occupied Vera Cruz, but Napoleon's projects were too bold for his allies, and they withdrew when it became clear that he contemplated nothing less than the establishment of a Mexican empire. This he did, after much stiff fighting, making the Archduke Maximilian of Austria, Emperor of Mexico in 1864. The French forces, however, remained in effectual possession of the country, and a crowd of French speculators poured into Mexico to exploit its mines and resources.
But in April, 1865, the civil war in the United States was brought to an end by the surrender of the great southern commander, General Lee, at Appomattox Court House, and the little group of eager Europeans in possession of Mexico found themselves faced by the victorious federal government, in a thoroughly grim mood, with a large, dangerous-looking army in hand. The French imperialists were bluntly given the alternative of war with the United States or clearing out of America. In effect this was an instruction to go. This was the entanglement which prevented Napoleon III from interference between Prussia and Austria in 1866, and this was the reason why Bismarck precipitated his struggle with Austria.
While Prussia was fighting Austria, Napoleon III was trying to escape with dignity from the briars of Mexico. He invented a shabby quarrel upon financial grounds with Maximilian and withdrew the French troops. Then, by all the rules of kingship, Maximilian should have abdicated. But instead he made a fight for his empire; he was defeated by his recalcitrant subjects, caught, and shot as a public nuisance in 1867. So the peace of President Monroe was restored to the new world. There remained only one monarchy in America, the empire of Brazil, where a branch of the Portuguese royal family continued to reign until
