What were 2 effects of the Spanish Conquest of The Aztec and Inca empires?

The Spanish Conquest of the Aztec and Inca empires led to the significant loss of life among indigenous populations due to warfare and the introduction of diseases like smallpox. Additionally, it resulted in the collapse of these powerful civilizations and the establishment of Spanish colonial rule, which facilitated the extraction of wealth, particularly silver, and the spread of Christianity throughout the Americas. This conquest also initiated a long-lasting cultural exchange and transformation, often to the detriment of indigenous traditions and social structures.
