In 1815 the Napoleonic wars having ended with the caging of the great soldier, Spain proposed to the Holy Alliance of European monarchs a joint European effort to restore her dominion over the revolted colonies in South America. But Napoleon had done his work too well to allow of any alliance, however "holy," to reassert the divine right of kings. Whilst he had been overthrowing the thrones of Europe, both in North and South America free nations had won recognition with the blood of their people. The United States, still nationally an infant, but sturdy withal, promulgated the Monroe doctrine as a veto on any European war of revenge against the South American Republics. Great Britain was more sympathetic to America than to the Holy Alliance. The momentarily re-established Kings and Emperors of Europe had therefore to hold their hand. It was a significant year, creating at once a free Latin America and a tradition that Latin America should look to Anglo-Saxon America for protection. Passing north of the Isthmus of Panama, there come up for consideration another group of Latin-American States of which the racial history resembles closely that of South America. The little cluster of Central American States can hardly be taken seriously. Their ultimate fate will probably be that of Cuba--nominal independence under the close surveillance of the United States. But, farther north, Mexico claims more serious attention. Some time before Peru had received the blessings of civilisation from Pizarro, Mexico had reluctantly yielded her independence to Cortez, a Spanish leader whose task was much more severe than that of Pizarro. Whilst the mild Peruvians gave up without a struggle, the fierce Mexicans contested the issue with stubbornness and with a courage which was enterprising enough to allow them to seize the firearms of dead Spanish soldiers and use them against the invaders. The original Aztec civilisation was warlike and Spartan. Extreme severity marked the penal codes. Intemperance, the consuming canker of Indian races, was severely penalised. There were several classes of slaves, the most unhappy being prisoners of war, who were often used as sacrificial victims to the gods. Sacrificed human beings were eaten at banquets attended by both sexes. The Aztecs were constantly at war with their neighbours, and needed no better pretext for a campaign than the need to capture sacrifices for their gods.
