USA HISTORY

Detailed explanation-1: -Spanish conquistador Hernán Cortés (c. 1485-1547) is best known for conquering the Aztecs and claiming Mexico on behalf of Spain. Cortés (full name Don Hernán Cortés de Monroy y Pizarro Altamirano, Marquis of the Valley of Oaxaca) first served as a soldier in an expedition of Cuba led by Diego Velázquez in 1511.

Detailed explanation-2: -Between 1519 and 1521 Hernán Cortés and a small band of men brought down the Aztec empire in Mexico, and between 1532 and 1533 Francisco Pizarro and his followers toppled the Inca empire in Peru.

Detailed explanation-3: -The Spanish were able to defeat the Aztec and the Inca not only because they had horses, dogs, guns, and swords, but also because they brought with them germs that made many native Americans sick. Diseases like smallpox and measles were unknown among the natives; therefore, they had no immunity to them.

Detailed explanation-4: -Having learned of political strife in the Aztec empire, Cortés led his force into the Mexican interior. On the way to Tenochtitlán, he clashed with local Indians, but many of these people, including the nation of Tlaxcala, became his allies after learning of his plan to conquer their hated Aztec rulers.
