So the Spanish arrived in Mexico in 1519 and in Peru in 1532, benefiting in both cases from total chaos due to disease. And after conquering the Inca and the Aztecs, they created an empire with two administrative divisions. The Viceroyalty of New Spain, founded in 1521, and the Viceroyalty of Peru, founded in 1542. In some ways, the Aztec and Inca empires were perfect for Spanish conquest. Their administrative structures were similar, there was a similar link between secular and religious power, albeit different religions.
