In 1519, Spain invaded Mexico, and in 1521, the capital of the Aztecs, Tenochtitlan, was conquered by the main enemies of Spain and the Aztecs, Tlaxcaltecs. But Spain did not completely conquer the Aztecs, but was completed only two centuries later, with two main reasons for the Spanish victory.

The Aztecs sacrificed many people every year because they believed that the universe would continue to operate because of the constant sacrifices of living persons, most of them from prisoners of war. But in time of peace, the Aztecs resorted to a formal "worship war" and became prisoners of war. Thus Tlaxcalteca was willing to join the Spanish army against the Aztecs.

Another important factor is that the Spaniards brought all sorts of plagues and infectious diseases to the Americas, plague, flu, plague, measles, hundreds of thousands of indigenous people were infected, these epidemics could cause about eight million indigenous people to die.

The Mexican War of Independence began in 1810, until the Liberation Army entered Mexico City in 1821, and the entire War of Independence was initiated by Miguel Hidalgo I Costa, who overthrew the Spanish rule on October 1, 1810, but the September uprising was planned due to the leakage of traitors, so early in the town of Dolores on September 16, after the successful establishment of the First Republic, with Guadalupe Victoria as its first president.
