In the early 16th century, Hernán Cortés led a group of Spanish conquistadors on a mission to conquer the Aztec empire, which at the time controlled much of what is now Mexico.
Cortés and his men arrived in the Aztec capital of Tenochtitlán in 1519, and they were initially welcomed by the Aztec ruler, Moctezuma II. However, tensions soon arose between the two groups, and Cortés began to plot against the Aztecs.
Over the next few years, Cortés and his men worked to gain the trust of the Aztecs while also secretly building up their military strength. They also formed alliances with other indigenous groups who were resentful of Aztec rule, and these allies proved to be crucial in the eventual conquest of the Aztecs.
In 1521, Cortés launched a full-scale attack on Tenochtitlán, aided by a smallpox outbreak that had decimated the Aztec population. The Aztecs put up a fierce resistance, but they were ultimately no match for the well-armed and -trained Spanish conquistadors. The Aztec empire fell, and Cortés and his men took control of the region.
The conquest of the Aztecs had far-reaching consequences, both for the Aztecs and for the history of the Americas. It marked the beginning of Spanish colonial rule in the region, and it had a profound impact on the indigenous people, who were subjected to exploitation and abuse under the new regime. The conquest of the Aztecs also set the stage for the colonization of other parts of the Americas, as other European powers followed in the footsteps of the Spanish.
