Explanation:

The conquistadores, such as Cortes and Pizarro "eventually lost control and were replaced with formal rule by the Spanish crown (Spanish government)."

Herman Cortes is known for being the Governor of New Spain between 1521 to 1524, with Cristobal de Tapia becoming Governor one New Spain in between. At some point, he had issues with the Governor of Cuba, Diego Velázquez de Cuéllar, which led to the recall of his expedition at the last moment.

He was later succeeded by the trio of Alonso de Estrada, Rodrigo de Albornoz, and Alonso de Zuazo.
